Answer:

<h2>c = 220</h2>

Step-by-step explanation:

f(x) = cx + d

<u>For the first equation</u>

f(50) = 27,000

Substitute the value of x that's 50 into the expression

That's

50c + d = 27,000

<u>For the second equation</u>

f(100) = 38,000

Substitute the value of x that's 100 into the expression

We have

100c + d = 38,000

Subtract the first equation from the second one to eliminate d

That's

100c - 50c + d - d = 38,000 - 27,000

50c = 11,000

Divide both sides by 50

We have the final answer as

<h3>c = 220</h3>

Hope this helps you

0.6×2=1.2 (no)

0.6×3=1.8 (no)

0.6×4=2.4 (no)

next distribute the negative 5, you will get - 40m, then 30.

combine like terms, and make sure its in standard form, - 30m^2 - 10m + 30
