The vertex of the parabola is 1 to the left and up 4.
Think of the vertex as where the curve starts.
Answer:
-3 and 1
Step-by-step explanation:
Hello!
The roots of the parabola are the intersections of the graph and the x-axis (y = 0).
Since the graph's vertex is above the x-axis and opens down, the graph has two roots.
The points of intersection are:
[tex](-3,0)[/tex][tex](1,0)[/tex]Therefore, the roots of the parabola are -3 and 1.

So
7x-14= 3x+ 12
Then subtract the x value from one side and move it to the other
Example
7x-14=3x+12
-3x. -3x
Therefore you’d have
4x-14=12
then move your negative 14
4x-14=12
+14 +14
4x=26
Divide both sides by 4
X=6.5
Answer:
x=6.5
Step-by-step explanation:
7(x-2)=3(x+4)
Step 1. Distribute
7x-14=3x+12
Step 2. Combine like terms and calculate
4x=12+14
Step 3. Divide 4 on both sides

The length of a rectangle is 3 meter shorter than3 times its width.Find the length and width if the perimeter is 210 meters
Answers
Answer:
length = 78 m , width = 27 m
Step-by-step explanation:
let w represent width then length l = 3w - 3
the perimeter (P) is calculated as
P = 2l + 2w = 210 , substitute values
2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side
6w - 6 + 2w = 210
8w - 6 = 210 ( add 6 to both sides )
8w = 216 ( divide both sides by 8 )
w = 27 and l = 3(27) - 3 = 81 - 3 = 78
Then length = 78 m and width = 27 m

A bank teller s two customers. Jerry makes a $20
withdrawal, so his balance changes by -$20. Hank makes
a $5 deposit, so his balance changes by $5.
Use absolute value to show the size of each transaction. Which transaction
involves more money?
O A. Hank’s deposit involves more money, because -20 is greater than
5.
O B. Hank’s deposit involves more money, because 1-20 is greater than
151
O C. Jerry’s withdrawal involves more money, because 1-20 is greater
than 51
O D. Jerry’s withdrawal involves more money, because 1-20 is less
than 151
Answers
Jerry's withdrawal involves more money because |-20| is greater than |5|
The vertical bars represent absolute value.
======================================================
Explanation:
Absolute value is the distance a number is from 0. I recommend drawing out a number line. You should see that -20 is further from zero compared to 5.
So this is a visual representation of why Jerry is dealing with more money. You can think of the positive version of each value, which is effectively what absolute value is doing, when comparing the values.
-20 becomes 205 stays at 5We see that 20 > 5, so Jerry is dealing with more money even though he's losing it rather than gaining it.

Equation of line p is y=x+7. Equation of a is y=-x+11. Prove that the lines are perpendicular
Answers
Answer:
The Answer is provided in the explanation!
Step-by-step explanation:
The lines are perpendicular because in both of the equations, the x variables are inverses. Meaning, that y=x+7, the x is positive, and y=-x+11, the x is negative. This shows that the slopes of both equations are 1, meaning the graph will have an X shape, provide that lines are perpendicular because they have an inverse of the same slope!

Step-by-steThe graph represents the heights of two climbers on a climbing wall over a 12-minute time period.
A graph titled The Climbing Wall where the horizontal axis shows time (minutes), numbered 1 to 12, and the vertical axis shows height (feet) numbered 2 to 24. The line labeled Brynn's climb begins at 0 feet in 0 minutes, to 15 feet from 5 to 7 minutes, to 0 feet in 10 minutes. The line labeled Abby's climb begins at 4 feet in 0 minutes, to 14 feet from 4 to 6 minutes, to 22 feet in 8 minutes, to 0 feet in 12 minutes.
Which statement is true about the climbers’ heights?
Brynn was resting at a constant climbing height when Abby’s climbing height was decreasing.
Abby’s climbing height was decreasing when Brynn’s climbing height was increasing.
The heights of both climbers increased, then decreased, with no rest at a constant height.
Both climbers rested on the wall at a constant height for 2 minutes.p explanation:
Fourth option is true, because both climbers had a 2-minute rest.
correct choice is D.
What is a graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter. Each object in a graph is called a node.
The graph represents the heights of two climbers on a climbing wall over a 12-minute time period.
Consider each graph separately.
Brynn's graph: The height was increasing from the start to the 5th minute. Then Brynn was resting 2 minutes at a constant climbing height, then the height was decreasing from the 7th minute to the 10th minute.
Abby's graph: The height was increasing from the start to the 4th minute. Then Abby was resting 2 minutes at a constant climbing height, then the height was again increasing from the 6th minute to the 8th minute and then the height was decreasing from the 8th minute to the 12th minute.
First option is false, because actually Abby was resting from 4th to 6th minutes and from 4th to 5th minute Brynn was still climbing.
Second option is false, because Abby’s climbing height starts decreasing later than Brynn's climbing height starts.
Third option is false, because both Brynn and Abby has a rest.
Fourth option is true, because both climbers had a 2-minute rest.
correct choice is D.

Normal curve A has a wider distribution than Normal curve B. The distribution A must has ____________.
A. a smaller mean
B. a larger standard deviation
C. a smaller standard deviation
D. a larger mean
Answers
The distribution A must has a smaller standard deviation. So, option C is correct.
What does "normal" describe in statistics?Normal usually refers to the word "normal" in normal distribution.
The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from mean, its chances decrease.
If we've got a normal distribution, then we can convert it to a standard normal distribution and its values will give us the z score.
If we have
[tex]X \sim N(\mu, \sigma)[/tex]
(X is following a normal distribution with mean and standard deviation )
then it can be converted to a standard normal distribution as
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
Normal curve A has a wider distribution than Normal curve B.
The distribution A must has a smaller standard deviation.

< (4x + 8) + < 72° = 180°
Combine like terms:
4x + 80 = 180°
Subtract 80 from both sides:
4x + 80° - 80° = 180° - 80°
4x = 100
Divide both sides by 4 to solve for x:
4x/4 = 100/4
x = 25
To verify whether the value of x is correct, substitute its value into the equality statement:
< (4x + 8)° + < 72° = 180°
< [4(25) + 8]° + < 72° = 180°
< (100 + 8)° + < 72° = 180°
< 108° + < 72° = 180°
180° = 180° (True statement. Therefore, the correct answer is x = 25).

clara has £7. she buys some chocolate bars at 63p each and has 7p left over. how many chocolate bars did she buy?
Answers
Answer:
11 bars
Step-by-step explanation:
Clara bought 11 chocolate bars. Let x be the number of chocolate bars Clara buys.
The cost of each chocolate bar is 63p, so the total cost of x chocolate bars is 63x pence.
After buying the chocolate bars, Clara has 7p left over.
Now we can write the equation:
Total money spent on chocolate bars + Money left over = Total money Clara has initially
63x + 7 = 700 (Since £7 is equivalent to 700p)
Now, let's solve for x:
63x = 700 - 7
63x = 693
x = 693 / 63
x = 11

are 46 and 105 relatively prime
Answers
Answer:
They are relatively prime.
Step-by-step explanation:
The prime factorization of 46 is 23 * 2, and the prime factorization of 105 is
3 * 7 * 5. Since there are no common factors, they are relatively prime.
There is no common prime number. Then the numbers 46 and 105 will be relatively prime.
What is relatively prime?When two quantities have just one similar, or if there is no additional value with the same quantity as one, you cannot divide them both and obtain zero as the remainder, two numbers are considered to be relatively prime.
The numbers are 46 and 105.
Then the factor of the number 46 will be
46 = 2 × 23
Then the factor of the number 105 will be
105 = 3 × 5 × 7
There is no common prime number. Then the numbers 46 and 105 will be relatively prime.
