Item 9
Write a linear function f with f(4)=−3 and f(0)=−2

y = -x/4 -2

Step-by-step explanation:

Linear function is in the form;

y = mx + b

The first point is (4,-3)

so we have;

-3 = 4x + b

The second point is (0,-2)

Thus;

-2 = 0(x) + b

b = -2

Put this in the equation above

-3 = 4x -2

-3 + 2 = 4x

4x = -1

x = -1/4

So the equation is;

y = -x/4 -2

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
