What is anequation of the line that passes through the points (-4, -1) and(6, -1)?
Answers
We are given the following two points
[tex](-4,-1)\text{and }(6,-1)[/tex]We are asked to find the equation of the line that passes through these points.
Recall that the equation of the line in slope-intercept form is given by
[tex]y=mx+b[/tex]Where m is the slope and b is the y-intercept.
The slope of the line is given by
[tex]m=\frac{y_2−y_1}{ x_2−x_1}[/tex][tex]\text{where}(x_1,y_1)=(-4,-1)\text{and}(x_2,y_2)=(6,-1)[/tex]Let us substitute the given values into the slope formula
[tex]m=\frac{-1-(-1)}{6-(-4)}=\frac{-1+1}{6+4}=\frac{0}{10}=0[/tex]So, the slope of the equation is 0
The equation of the line becomes
[tex]y=0x+b[/tex]Now let us find the y-intercept (b)
Choose any one point from the given two points
Let choose (-4, -1) and substitute it into the above equation
[tex]\begin{gathered} y=0x+b \\ -1=0(-4)+b \\ -1=0+b \\ b=-1 \end{gathered}[/tex]Therefore, the equation of the line in slope-intercept form is

how much accumulated interest should the investor expect at the end of 10 years?
Answers
Answer:
The correct option is D
The accumulated interest after 10 years is $2,125.00
Explanation:
We have the following parameters:
Principal (P) = $2,500

Time (T) = 10 years
To calculate the interest after 10 years, we use the formula:
[tex]A=\frac{PRT}{100}[/tex][tex]\begin{gathered} A=\frac{2500\times8.5\times10}{100} \\ \\ =2125 \end{gathered}[/tex]The interest is $2,125

How to use equation to represent a problem?He is thinking of two positive numbers.
If we triple the first number and double the second number, the sum is 34.
If we take half of the first number and double the second, the sum is 14.
Therefore, the equation that can be used to solve the situation is as follows:
let
x = first number
y = second number
3x + 2y = 34
1 / 2x + 2y = 14
Therefore,
3x + 2y = 34
1 / 2x + 2y = 14
5 / 2 x = 20
5x = 40
x = 40 / 5
x = 8
3(8) + 2y = 34
2y = 34 - 24
2y = 10
y = 10 / 2
y = 5

Find Point F so that angle ABC is = to angle DEF
Answers
Answer
(5, 2)
Step-by-step explanation
Point D in triangle DEF is the equivalent to point A in ABC. Similarly, E is the equivalent to B. In consequence, F is the equivalent to C.
We can obtain points D and E by translating points A and B 6 units to the right and 4 units up.
Translation 6 units to the right and 4 units up transforms the point (x, y) into (x+6, y+4). Applying this rule to point C:
C(-1, -2) → (-1+6, -2+4) → F(5, 2)

Alyssa's algebra test score was 8 points lower than Jennifer's. The total of their two tests was 180. What did each girl receive?
Answers
Based on the equation, each girl received the following Algebra test scores:
Alyssa's = 86 pointsJennifer's = 94 points.What is an equation?An equation is a mathematical expression that claims that two values are equivalent.
Equations use the equation symbol (=) to illustrate the equality of two or more expressions.
Algebraically, let Alyssa's algebra test score = x
Let Jennifer's test score = x + 8
The total of their two tests = 180
x + x + 8 = 180
2x + 8 = 180
2x = 180 - 8
2x = 172
x = 86 (172/2)
Alyssa's test score = 8 points lower
Shareable points = 172 (180 - 8)
Each received 86 points from the shareable points
Alyssa's test score = 86 points
Jennifer's test score = 94 points
Check:
86 + 94 = 180
94 = 8 points greater than 86
Thus, using an equation, we can conclude that Alyssa scored 86 points on the Alegra test, which is 8 points less than Jennifer's 94 points.

Answers
The required probability is 1/31 that the family has 5 girls if it is known that the family's first child is a girl.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Let us express every possible set of 5 children as a 5-letter word made up of the letters G or B. (G for a girl and B for a boy).
In all, 2⁵ = 32 such words are outcomes, with two options for each of the five slots.
The constraint "if it is known that the family contains at least one female" suggests that we would evaluate the reduced space of all such words, except the word (BBBBB).
This reduced event space is made up of 32-1 = 31 elements.
There is just one such term in the favorable collection of events (GGGGG).
As a result, the probability for the question is P = 1/31.

Mary has scored 78, 60, 82, 94, and 88 on her previous fice tests.
What score does she need on her next test so that her average (mean) is 80?
Let x be the next test score
Recall that the mean is given by
[tex]mean=\frac{\text{sum of test scores}}{total\text{ numbers of tests}}[/tex]We have the following information,
mean = 80
sum of test scores = 78 + 60 + 82 + 94 + 88 + x = 402 + x
total number of tests = 6
So, let us substitute these values into the above formula
[tex]\begin{gathered} mean=\frac{\text{sum of test scores}}{total\text{ numbers of tests}} \\ 80=\frac{402+x}{6} \\ 6\times80=402+x \\ 480=402+x \\ 480-402=x \\ 78=x \\ x=78 \end{gathered}[/tex]Therefore, Mary need to score 78 on her next test so that her mean is 80

Liz bought 7.396817 quarts of orange juice for a party.
What are Quarts?The liquid quart in the United States is a measure of fluid volume equal to one-fourth of a gallon, two pints, or four cups. The liquid quart is not to be confused with the dry quart (US) or the imperial quart, which are two distinct units.
Multiply the volume by the conversion ratio to transform a liter measurement into a quart measurement.
Since each liter equals 1.056688 quarts, you may use the following easy formula to convert:
quarts = liters × 1.056688
The volume in quarts is equal to the liters multiplied by 1.056688.
We have been given that Liz bought seven liters of orange juice for a party.
We have to convert 7 liters to quarts using the formula above.
7 L = (7 × 1.056688) = 7.396817 qt

Answers
Explanation:
1)
1 kilometer is equal to 1000 meters:
1 km = 1000 m
So,
1m = 1/1,000 km
To complete the table, we can use the rule of three:
a) 1,000 m?
1m - 1/1,000 km
1,000m - x
x = 1/1000 * 1,000 = 1 km
As we can see, we only have to divide the measure in meters by 1000.
b) 3,500 m = 3,500/1,000 = 3.5 km
c) 500 m = 500/1,000 = 0.5 km
d) 75 m = 75/1,000 = 3/40 km = 0.075 km
e) 1 m = 1/1000 = 0.001 km
f) x = x/1,000 = 0.001x km
2)
The relation is:

A. Find f(1/2 pie)
B. Find the all values x when f(x)=0. Use a comma to separate each value.
C. Fine the range. Write it in Interval notation.

A. [tex]f(\frac{1}{2}\pi)=2[/tex]
B. [tex]x=-2\pi, -\pi, 0, \pi, 2\pi[/tex]
C. [tex][-2, 2][/tex]
Step-by-step explanation:
A:
Since we want to find: [tex]f(\frac{1}{2}\pi)[/tex], all we do is go that that x-value on the function and then go either up or down until we find where the y-value is at that x-value, because [tex]f(\frac{1}{2}\pi)[/tex] is just another way of expressing "the y-value of the function f, at [tex]x=\frac{1}{2}\pi[/tex]
In this case it turns out that the y-value is two, which you can verify by going to that x-value and finding where the y-value is at that point.
So: [tex]f(\frac{1}{2}\pi)=2[/tex]
B.
To find all the x-values such that: [tex]f(x)=0[/tex], we just need to find where the graph crosses the x-axis, also known as an x-intercept. This is because at an x-intercept, the y-value will be equal to zero.
Looking at the graph you can see that these x-intercepts occur at: [tex]x=-2\pi, -\pi, 0, \pi, 2\pi[/tex]
in general you'll notice that all the values are actually separated by a value of pi, so the general formula for a zero in this equation is likely going to be: [tex]x=\pi n\text{ where n is an integer}[/tex], since trigonometric functions are periodic, they repeat.
C.
Looking at the graph you'll notice the value is increasing, then decreasing, then increasing... and so on.
The max value it reaches is two, and the min value it reaches is negative two.
The range of a function is the y-values that the function can output, considering all the possible inputs, or the domain.
In this case no matter the input we can only output values between -2 and 2.
In this interval notation, we use brackets, since the minimum and maximum possible values are included in the range, since the function does output 2 and -2, it doesn't just "approach" it.
So we get a range of: [tex][-2, 2][/tex]

Dividing exponents is the same as subtracting the exponents, so
[tex]\frac{m^{9}}{m^{3}} =m^{9-3}=m^{6}[/tex]
[tex]\frac{n^{5}}{n^{5}} =n^{5-5}=n^{0}=1[/tex]
So now our equation looks like
[tex]\frac{8.4m^{6}}{2.1}[/tex]
Now we can divide the numbers
8.4/2.1 = 4
So your final answer is [tex]4m^{6}[/tex]
