Write a linear equation for the graph in point-slope form. Show your work. (2 points)
Use your equation to determine how long Grace was at birth. Show your work and explain how you can check your result using your knowledge of rate of change. (3 points)
Based on the data, how long do you predict baby Grace will be at 36 months of age? Use the rate of change to justify your answer. Does your answer make sense? Explain. (2 points)
The point-slope intercept equation is y - 20 = 3/4(x - 4).
The rate of change is 3/4.
At 0 months (at birth), Grace was 17 inches long.
At 36 months, Grace would be 44 inches long.
How to Create a Linear Equation?A linear equation of a graph can be represented in point-slope form as y - b = m(x - a), where (a, b) is a point on the graph and m is the slope.
Find the Slope (m) using two points (4, 20) and (8, 23):
Slope (m) = change in y/change in x = (23 - 20)/(8 - 4)
Slope (m) = 3/4
Substitute (a, b) = (4, 20) and m = 3/4 into y - b = m(x - a):
y - 20 = 3/4(x - 4) [point-slope intercept equation]
At birth, months would be x = 0. To find how long Grace was at birth, substitute x = 0 into y - 20 = 3/4(x - 4) to find the value of y:
y - 20 = 3/4(0 - 4)
y - 20 = 3/4(-4)
y - 20 = -3
y - 20 + 20 = -3 + 20
y = 17
This means that, at 0 months (at birth), Grace was 17 inches long.
At 36 months, substitute x = 36 into y - 20 = 3/4(x - 4) to find the how long Grace was (y):
y - 20 = 3/4(36 - 4)
y - 20 = 3/4(32)
y - 20 = 24
y - 20 + 20 = 24 + 20
y = 44
At 36 months, Grace would be 44 inches long.

Suppose f(x)=x^2+9x+8
1. Suppose F(x) is obtained by reflecting the graph over the y-axis. Find a formula for F(x).
Suppose g(x)=x^19-8x^6-x^5+7x^2+x+9.
1. Reflected over x-axis vertically
2. Reflected over y-axis horizontally
Using translation concepts, the functions are given as follows:
1. F(x) = x² - 9x + 8.
2. [tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
In item 1, the function is:
f(x) = x² + 9x + 8.
When the function is reflected over the y-axis, we have that:
F(x) = f(-x),
Hence:
F(x) = (-x)² + 9(-x) + 8.
F(x) = x² - 9x + 8.
For item 2, the function is:
[tex]g(x) = x^{19} - 8x^6 - x^5 + 7x^2 + x + 9[/tex]
When the function is reflected over the x-axis, we have that:
G(x) = -g(x).
Hence:
[tex]G(x) = -x^{19} + 8x^6 + x^5 - 7x^2 - x - 9[/tex]
When the function is reflected over the y-axis, we have that:
Hence:
G(x) = G(-x).
[tex]G(x) = -(-x)^{19} + 8(-x)^6 + (-x)^5 - 7(-x)^2 - (-x) - 9[/tex]
[tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]

The easiest thing is to convert it to an improper fraction.
-2 1/9 turns into -19/9. -4 1/9 turns into -37/9.
-19/9 - (-37/9) here you would add because you are subtracting a negative number.
-19/9 + 37/9 change it to positive and then add.

Answer: 0.24, 3/8, 0.51, 0.517, 0.59, 3/4
Step-by-step explanation:
First you will have to convert the 3/4 and 3/8 to a decimal number. By doing this 3/4 turns into 0.75 and the 3/8 becomes 0.375. After this step you then arrange the numbers for the lowest of 0.24 then the 3/8 (0.375) next 0.51 after that is 0.517 then 0.59 and final after that 3/4

45 45 50 50 55 60 70 75 75 80
80 85 85 85 85 90 95 95 95 100
a) Find the mean (or average) score, the mode, and the median score.
b) Which of these three measures of central tendency do you think is the least representative of the set of scores?
Answer:
Mean = 75
Median = 80
Mode = 85
The mode
Step-by-step explanation:
Given the data :
45 45 50 50 55 60 70 75 75 80 80 85 85 85 85 90 95 95 95 100
Rearranged data :
45, 45, 50, 50, 55, 60, 70, 75, 75, 80, 80, 85, 85, 85, 85, 90, 95, 95, 95, 100
The mean score :
ΣX / n ; n = sample size = 20
ΣX = 1500
Mean = 1500 / 20 = 75
Mode = most frequently occurring = 85 ( frequency of 4)
Median = 0.5(n + 1)th term
Median = 0.5(20 + 1)th term
Median = 0.5(21) th term
Median = 10.5th term = (10 + 11)th term / 2
Median = (80 + 80) / 2 = 160 / 2 = 80

The bakers at Healthy Bakery can make 170 bagels in 2 hours. How many
bagels can they bake in 14 hours? What was that rate per hour?
Given:
The bakers at Healthy Bakery can make 170 bagels in 2 hours.
To find:
How many bagels can they bake in 14 hours and the rate per hour.
Solution:
We have,
Number of bagels the bakers can bake in 2 hours = 170 bagels
Number of bagels the bakers can bake in 1 hours = [tex]\dfrac{170}{2}[/tex] bagels
= 85 bagels
Therefore, the average rate is 85 bagels per hour.
Number of bagels the bakers can bake in 14 hours = [tex]14\times 85[/tex] bagels
= 1190 bagels
Therefore, the bakers can bake 1190 bagels in 14 hours.

Triangle ABC is shown the measure of the interior angle at point A is 40 and the exterior angle point C is 102
Answer:
∠C (Interior) =78°
∠B (Interior) = 62°
Step-by-step explanation:
Given:
∠A (Interior) = 40°
∠C (exterior) = 102°
Computation:
∠C (Interior) = 180° - 102°
∠C (Interior) =78°
∠B (Interior) = 180° - ∠A (Interior) - ∠C (Interior)
∠B (Interior) = 180° - 78° - 40°
∠B (Interior) = 180° - 118°
∠B (Interior) = 62°

Antonio harvested 100 1/2 kg of fruits from his farm and he sold 30 2/3 kg of durian and 34 5/6 kg of mangosteen. How many kilograms of fruits were not sold?
Answer:
the number of kilograms of fruits that are not sold is 35
Step-by-step explanation:
The computation of the number of kilograms of fruits that are not sold is as follows:
The equation would be
100 1 ÷ 2 - 30 2 ÷ 3 - 34 5 ÷ 6
100 3 ÷ 6 - 30 4 ÷ 6 - 34 5 ÷ 6
99 9 ÷ 6 - 30 4 ÷ 6 - 34 5 ÷ 6
69 5 ÷ 6 - 34 5 ÷ 6
35
