Answer:
-41
Step-by-step explanation:
the problem is basically saying that we need to first substitute 5 in for x in the f(x) function first.
then we need to take that answer that we got and substitute it for x in the g(x) function.
i will do this step by step for you
start with the f(x) function
f(x) = 4x + 3
substitute 5 in for x
f(x) = 4(5) + 3
solve
f(x) = 20 + 3
f(x) = 23
now we use our answer from the f(x) function we just solved, and we put it into the g(x) function.
basically you are going to now substitute 23 for x in the g(x) function.
i will also do this step by step for you.
take the g(x) function
g(x) = -2x + 5
substitute 23 for x
g(x) = -2(23) + 5
solve
g(x) = -46 + 5
g(x) = -41
<u>so now your overall answer is -41.</u>
<u>hope this helped!!!! good luck <3</u>
Answer:
x=0.3
Step-by-step explanation:
6x+3+4x=1/2(9+10x)
10x+3=4.5+5x
5x=1.5
x=0.3
Answer:
1.1x
x + 0.1x
Step-by-step explanation:
The manager of a store marks up all items by 10%.
So, if the original price of any item is x, then increase for markup is 10% of x i.e. .
Hence, the expression that represents the new price with the markup is (x + 0.1x) = 1.1x.

Answer:
It is not equivalent.
Step-by-step explanation:
You have to expand the brackets :
(x-4)(x+3)
= x(x) + x(3) - 4(x) - 4(3)
= x² + 3x - 4x - 12
= x² - x - 12
Therefore, x² - x - 12 / (x-4)(x+3) is not equivalent to x² - 4x - 12.
