Answer:
Step-by-step explanation:
Simplifying
8x + 5y = 27.15
Solving
8x + 5y = 27.15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
8x + 5y + -5y = 27.15 + -5y
Combine like terms: 5y + -5y = 0
8x + 0 = 27.15 + -5y
8x = 27.15 + -5y
Divide each side by '8'.
x = 3.39375 + -0.625y
Simplifying
x = 3.39375 + -0.625y
Answer:
Square is the correct answer
Average rate of change is 0
Interpretation: The crop yield did not change from year 5 to year 15
<em><u>Solution:</u></em>
The function that models the yield is:

The average rate of change of f(x) from x = a to x = b is given by the formula:

Find and interpret the average rate of change from year 5 to year 15


<em><u>Thus average rate of change:</u></em>


Thus Average rate of change is 0
Interpretation: The crop yield did not change from year 5 to year 15.
I think it’s A because 4*2 is 8 and if n were quadrupled it would be 2
Answer:
f(x) = 5x - 5
Step-by-step explanation:
Let the equation of the linear function is,
f(x) = mx + b
Here, m = Slope of the graph
b = y-intercept
Slope of the line passing through
and
is given by,
m = 
From the table attached,
Slope of the line passing through (2, 5) and (6, 25) will be,
m = 
m = 5
Equation of the linear function will be,
f(x) = 5x + b
Since, a point (10, 45) lies on the function,
45 = 5(10) + b
b = 45 - 50
b = -5
Equation of the linear function will be,
f(x) = 5x - 5
