So Valeria has 26 signatures as her starting point, and 6 signatures a day (x) as her rate. In slope-intercept (y = mx + b) form, this would be written y = 6x + 26, with y being the total number of signatures on x day.
Christina has 53 signatures as her starting point, and 3 signatures a day (x) as her rate. In slope-intercept (y = mx + b) form, this would be written y = 3x + 53, with y being the total number of signatures on x day.
To figure out how many days would it take to have the same amount of signatures, meaning the same y values, we have to set the equations equal to each other (bc each have the same y value as the other so they basically equal each other). That would mean:
6x + 26 = 3x + 53
To simplify this, get the numbers to one side and the xs to another by subtracting 3x and 26 from both sides. This would make it:
3x = 27, in which we can divide both sides by 3 to get x = 9. So the number of days after which they would have the same amount of signatures would be 9.
Now since we know the shared x value, we just plug it into one of the equations to get the resulting y value. I’ll pick Christina’s.
y = 6(9) + 26, which is 54 + 26, which is 80. So the number of signatures they both will have when they reach the same number is 80.
Hope this helps.

Answers
Answer:
x = - 2 , x = 6
Step-by-step explanation:
x² - 4x = 12 ( subtract 12 from both sides )
x² - 4x - 12 = 0 ← in standard form
to factor, consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 4)
the factors are - 6 and + 2 , since
- 6 × 2 = - 12 and - 6 + 2 = - 4 , then
(x + 2)(x - 6) = 0 ← in factored form
equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 6 = 0 ⇒ x = 6

Answers
Mrs. Tran's son mowed more land than she and 9/28 of the land still need to be mowed.
let us convert all the fractions into equivalent fractions to make our calculations easy.
The land mowed by Mrs Tran = 1/4 x 7/7 = 7/28
The land mowed by her son = 3/7 x 4/4 = 12/28
Hence, we can clearly see that Mrs. Tran's son mowed more land than she.
The total land mowed by both of them = 7/28 + 12/28
= 19/28
The total land to be mowed = 1 - 19/28
= (28 - 19)/28
= 9/28
Hence, the land still to be mowed is 9/28.

Does the function model exponential growth or decay? f(t)= 5*7/3^t
Answers
Answer:
Read it carefully below
Step-by-step explanation:
Based on the formula you provided, the function appears to model exponential decay. In general, exponential decay occurs when the growth rate of a quantity is proportional to its current value, and the growth rate is a fixed constant less than 1.
In this case, the growth rate is given by the constant factor 7/3 (which is less than 1), and the function uses the variable t as the exponent. As t increases, the value of the function decreases exponentially.

Determine if the lines are parallel, perpendicular, neither or coinsiding..
y=-3x+7
y = 3x - 7
A Perpendicular
B neither
C Parallel
D Coinciding
Answers
Answer:
neither
Step-by-step explanation:
The slopes are neither equal nor negative reciprocal.
Answer:
B
Step-by-step explanation:
The lines are B. Neither.
To determine whether two lines are parallel, perpendicular, neither, or coinciding, we can look at their slope. The slope of a line is a measure of how steep the line is. It is calculated by taking the difference in the y-coordinates of two points on the line, and dividing it by the difference in the x-coordinates of those points.
In this case, the two lines have the equations y = -3x + 7 and y = 3x - 7. To find their slopes, we can plug in the coordinates of two points on each line, and then calculate the slope using the formula mentioned above.
For the first line, we can use the points (0, 7) and (1, 4) to calculate the slope:
Slope = (4 - 7) / (1 - 0) = -3
For the second line, we can use the points (0, -7) and (1, -4) to calculate the slope:
Slope = (-4 - (-7)) / (1 - 0) = 3
Since the slopes of the two lines are the opposite of each other (i.e. one is positive and the other is negative), the lines are not perpendicular or coinciding to each other. This means that they do intersect at a right angle, and are not parallel or coinciding. Therefore, the correct answer is B, neither.

Answer: The mean score for this class is 17.13.
Step-by-step explanation:
Add up all of the scores for the boys: 78 + 58 + 79 + 45 + 39 = 249
Add the mean score for the girls: 249 + 8 = 257
Add up the number of students in the class: 10 + 5 = 15
Divide the total score by the number of students to find the mean: 257 / 15 = 17.13
What do you understand by mean and how many methods are there to find it ?
Mean is a statistical term that refers to the average value of a set of data. There are two main methods for finding the mean:
Arithmetic mean: This is the most common method of calculating the mean. It is simply the sum of all the values in the set of data, divided by the number of values in the set.
Geometric mean: This method is used when the data set includes both positive and negative values. It is the nth root of the product of all the values in the set, where n is the number of values in the set.
There are also other methods for finding the mean, such as the harmonic mean, the weighted mean, and the trimmed mean, but these are less commonly used.
To find the mean score for the entire class, we need to add up all of the scores and divide by the total number of students. First, let's start by adding up all of the scores for the boys. We have: 78+58+79+45+39 = 249
Next, let's add the mean score for the girls, which is 8.
So the total is now: 249 + 8 = 257.
Now we need to divide this total by the number of students in the class to find the mean score. There are 10 boys and 5 girls in the class, for a total of 10 + 5 = 15 students.
Therefore, the mean score for this class is :

how do i find the equation of the line
Answers
Answer: look at explanation <3
Step-by-step explanation:
Steps to find the equation of a line from two points:
Find the slope using the slope formula
Use the slope and one of the points to solve for the y-intercept (b).
One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.
Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.

Answers
When two friends are playing a video game where the player goes on quests to earn coins with an average number of 2000 coins earned in a quest, if one plays an average of 20 quests a day and other play 5 quests a day, none of them are likely to record an average earning below 1500 coins in a day.
Therefore the answer is both Heather and Suzanne are less likely to record an average earning below 1500 coins.
Here the average number of coins earned in a quest is not dependent on the number of quests played in a day. So for both Heather and Suzanne the average earning is to be 2000, so they are less likely to earn below 1500 coins.

The option that correctly describes the given box plot is; e. approximately half of the males in the sample of customers spent at least as much time in the store as any females in the sample of customers.
How to interpret boxplot in statistics?A box plot is defined as a method for graphically showing the locality, spread and skewness groups of numerical data through their quartile.
Some of the terms in box plot is as follows;
Minimum Score; This is the lowest score, that excludes the outliers (located at the end of the left whisker).
Lower Quartile; This is twenty-five percent of scores that fall below the lower quartile value (the first quartile).
Median; This is the mid-point of the data and is shown by the line that divides the box into two parts.
Now, looking at the box plot in the given attachment, we see that the middle line on a boxplot graph is the same as the median of the data, which for the males was equivalent to the highest value for females. This tells us that approximately half of the males spent more time in the store than any females.

The ratio of a to b is 3:5. The difference between angle a and b is 36°. What is the size of angle C
No links please it’s been bugging me for 30 minutes
Answers
Answer:
The ratio of a to b is 3:5, which means that the value of a is 3/8 of the value of b. This means that if the difference between the angles a and b is 36°, then the size of angle a is 3/8 * 36° = 9°.
To find the size of angle C, we need to add the size of angle a to the size of angle b. Since the size of angle a is 9° and the difference between the sizes of angles a and b is 36°, the size of angle b is 36° + 9° = 45°.
The size of angle C is the sum of the sizes of angles a and b, so the size of angle C is 9° + 45° = 54°. Therefore, the size of angle C is 54°.

How to calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
In this case, the original is 180 and the new is 150. The percentage decrease will be:

An expression, rule, or law that specifies the relationship between two variables is known as a function in mathematics (the dependent variable). Functions abound in mathematics, and the sciences rely on them to build physical links.
If any vertical line drawn through the graph may only cross it once, it is a function. If there are any points on the graph where a vertical line might cross it twice or more, the graph is not a function.
In a spreadsheet program, a function is a programmed calculation, whereas an Excel formula is an equation that the user has developed.
The functions are
f(x) = 2.5x - 10.5
g(x) = 64(0.5x)
x = 3 to 5 results in:
f(3) = 2.5(3) - 10.5 = -3
f(4) = 2.5(4) - 10.5 = -0.5
f(5) = 2.5(5) - 10.5 = -2
x = 3 to 5 results in:
g(3) = 64(0.5³)= 8
g(4) = 64(0.5x4) = 4
g(5) = 64(0.5x 5)= 2

Answer: x = 40 degrees
Step-by-step explanation:
Quick Maths
Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
so,
180 = 60 + 80 + APQ
APQ = 180 - 60 - 80 = 40°
the triangles APQ and ABC are similar. one meaning of that is that they have the same angles.
so,
x = angle APQ = 40°
anufacturing machine has a 5% defect rate. if 4 items are chosen at random, what is the probability that at least one will have a defect?
Answers
The probability that at least one will have defect is 0.1855 if a manufacturing machine has a 5 % defect rate.
If manufacturing machine has 5% defect rate. The probability is ration of the number of favorable outcomes. Probability is the branch of math in which we calculate he number of observation and favorable outcomes of a certain event to be occur. if the manufacturing company has 5% defect rate then there is also to find the number probability of non defect rate. so,
Probability of defect (p) = 0.05
Probability of non defect (q) = 1- 0.05 = 0.95
4 items are chosen at random .
We have to calculate the probability that at least one will have a defect.
Now ,
P ( at least one will have defect ) = 1 - P ( None will have defect )
P ( none will have defect) = 1 × 1 × 0.81450625
P (none will have defect) = 0.81450625
putting the value we get,
P ( at least one will have defect) = 1 - 0.81450625
P ( at least one will have defect) = 0.18549375
P ( at least one will have defect) = 0.1855
