Answer:

here (edit I made a mistake)

Step-by-step explanation:

9) y=\frac{3}{5} x +5

10) y = x - 3

11)  y=-\frac{3}{5} x - 3

12) y=\frac{5}{4} x + 2

these are the slop int forms, my bad...

sorry

Multiplies to -1120 adds to 3
TEA [102]
With these, always write out the multiples first.

Start like this:
(assume one of the factors is negative)
1 and 1120
2 and 560
4 and 280
5 and 224
7 and 160
8 and 140
10 and 112
14 and 80
16 and 70
20 and 56
28 and 40
32 and 35

from those, the obvious choice is the one with a difference of three. In this case, 32 and 35, because -32 + 35 equals 3.

10)
Kipish [7]

Answer:

-600

Step-by-step explanation:

The rate of change of a function f(x) in a certain interval (x_1,x_2) is the ratio between the change of the function and the change in the value of x:

r=\frac{f(x_2)-f(x_1)}{x_2-x_1}

The rate of change of a function tells how much the value of the function is changing per change in unit of x: therefore, for a linear function it corresponds to the slope of the line.

In this problem, the function f(x) is equal to the value of the business machine in dollars, while the variable x represents the number of years.

Here we are told that the machine was purchased for

q=\$4500

while its value decreases by $600 each year, so

m=-600\$

This means that the linear function that represents the value of the machine after x years is:

y=4500-600x

Therefore, the rate of change of the function is -600.
