Replace x with -4 so it would be:
f(-4)= 2(-4)=-8
-8 is your answer
Answer:439.2$
Step-by-step explanation:
So first there are 52 people who use the cleaning service right? therefore lets do 52 people times the amount paid each month 12.20$ = 634.4$
16 members in the first week times 12.20 = 195.2$
so then subtract 634.4-195.2= your answer of 439.2 $ were collected the second week
First: work out the difference (decrease) between the two numbers you are comparing. Then divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage increase. :)
Left one i think thats the one
Answer: -8
Explanation: If g(x) = x² + 2x - 8, then g(-2) = (-2)² + 2(-2) - 8
which simplifies to 4 + (-4) - 8 or 0 - 8 which is -8.
Remember to always use parentheses when
substituting your given value in for <em>x</em>.
