Answer:
2 more pieces because you can estimate 1/7 to 2 and 3/5 to 4
Step-by-step explanation:
The equation of best fit is y = (-22/5)x + 10.
What is an equation of a line?
The equation of a line is given by:
y = mx + c where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The following coordinates are given:
Pick two coordinates.
(0, 10) and (25, -100)
The equation of best fit.
y = mx + c
Now,
m = (-100 - 10) / (25 - 0)
m = -110 / 25
m = -22/5
Now,
(0, 10) = (x, y)
10 = (-22/5) x 0 + c
c = 10
Now,
y = mx + c
y = (-22/5)x + 10
Thus,
Using the coordinates the equation of best fit is y = (-22/5)x + 10.

Answer:
k=13
Step-by-step explanation:
19 + 12k = –k − 20
19+20=39=13k
k=13
Answer:
120 ft. sq
Step-by-step explanation:
You use the equation length times width to find the area. 15 x 8 = 120. This equation works for any rectangle
Answer:
18x² + 5
Step-by-step explanation:
To evaluate f(g(x)), substitute x = g(x) into f(x)
f(g(x))
= f(6x²)
= 3(6x²) + 5
= 18x² + 5
