Answer:
8×10^21
Step-by-step explanation:
<span>-6f+13=2f-11
-6f - 2f = -11 - 13
-8f = -24
f = 3</span>
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
Answer: f(x)=(x+2)(x−4) because you can see when each factor is equal to zero.
