Answer:

x = -3

Step-by-step explanation:

12 - 4x-5x = 39

Combine like terms

12 - 9x = 39

subtract 12 from each side

12 -9x-12 = 39-12

-9x = 27

Divide by -9

-9x/-9 = 27/-9

x = -3

180 = 30 * x    /30
x = 180 / 30
x = 6 gallons of water

A lawn-mowing company is trying to grow its business. It had 26 clients when they started its business and wants to increase by
SCORPION-xisa [38]

Answer:

f(x) = 3x + 26; 26 ≤ y ≤ 35

Step-by-step explanation:

This makes a linear equation.

y=mx+b

where m is the amount they want to increase each week

and b is the initial value i.e 26 clients.

Now substitute the values in the equation.

Let x=0

y=3(0)+26

y = 26

Now let x= 3

y=mx+b

y=3(3)+26

y=9+26

y=35

Thus the correct option is B.

f(x) = 3x + 26; 26 ≤ y ≤ 35 .....
