Step-by-step explanation:
2x = 18
Divide both sides by 2
x = 9
ANSWER
The value of this function at x=-1 is 1
EXPLANATION
The given function is
We want to find the value of this function at x=-1.
We substitute x=-1 into the function to obtain:
We multiply out to obtain:
Therefore the value of this function at x=-1 is 1.
Answer:
Each team ran (scored) 90 runs.
Step-by-step explanation:
Don't really know how to explain it but I'll show what I did.
First I understood that for every 9 runs team A runs, team B runs 7.
This means that if we multiply 9 by a number, we have to multiply 7 by the same number.
Now that we understand this, we need to figure out a number that when multiplied with 7 and 9 then added together equals 1440.
I'm pretty sure there was an easier way to do this but I did it the way I know will for sure give me the right answer and that's estimating that mystery number until you get it. Sorry my explanation wasn't the best.
Work:
9 x 90 = 810
7 x 90 = 630
810 + 630 = 1440
Answer:
x = -4 x = 3
Step-by-step explanation:
To find the x intercepts, set y =0
(x+4) (-x+3) =0
Using the zero product property
x+4 =0 -x+3 =0
x = -4 x = 3
