Answer:
Step-by-step explanation:
3(n+4)=2n-8
3n+12=2n-8
5n= -20
n= -4
Answer:
I think it's non linear because the 1 to 1 wouldn't work
f(-12) = -12(-12) + 100 = 144 + 100 = 244
Answer:
2.088
Step-by-step explanation:
Trust me I am in high school honors algebra with almost an average of 100.
Some number y has 7 subtracted off to get 15. We have y-7 = 15. To isolate y, we have to undo the "subtract 7" operation that happens to y. We have to add 7 to both sides.
y-7 = 15
y-7+7 = 15+7
y = 22 is the answer
