A lawn-mowing company is trying to grow its business. It had 26 clients when they started its business and wants to increase by
Likurg_2 [28]

Answer:

B. f(x) = 3x + 26;26≤ y ≤ 35

Step-by-step explanation:

This would be a linear equation in the form

y= mx+b

where b is the initial value (or 26 clients)

m is the slope, or the amount they want to increase by each week

y = 3x+26

Let x =0

y = 26 or what we start with

Let x =3, or be week 4 (we started with x= 0)

y = 3*3 +26

y =9+26

y= 35

Three times a number minus thirty-two
lbvjy [14]

Answer:

3n−32=7n+28

n=-15

Step-by-step explanation:

Let's solve your equation step-by-step.

3n−32=7n+28

Step 1: Subtract 7n from both sides.

3n−32−7n=7n+28−7n

−4n−32=28

Step 2: Add 32 to both sides.

−4n−32+32=28+32

−4n=60

Step 3: Divide both sides by -4.

−4n/−4=60/−4

n=−15

Can you guys help me with integers it these four problems for the first image do 18 and 19 for the second it’s 7 and 11 please h
xxMikexx [17]

Answer:

18. 20,000.

19. 0

7. 1

11. 101

Step-by-step explanation:

18. I think is stays the same, because an integer is a number that is not a fraction. So still 20,000.

19. Sea level is at zero altitude. So answer is 0.

7. |17-16| = |1| = 1. The lines around it are called absolute value signs and mean to make the answer positive.

11. |-101| = 101. As said before the lines mean to make the inside part positive.
