(c) Paul uses the function y = 7x + 30 to model the situation. What score does Paul’s model predict for 3 hours of homework? (d) Describe what the number 30 in Part (c) mean in the context of the situation?

(c) Paul's model predicts a score of 51 for 3 hours

(d) 30 represents the y intercept

Step-by-step explanation:

Given

Solving (c): What is y when x is 3

Substitute 3 for x in

Solving (d): What does 30 represent

An equation is represented as:

Where

Compare: to

This implies that 30 represents the y intercept

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
