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

so now your overall answer is -41.

hope this helped!!!! good luck <3

Answer:

43.4

Step-by-step explanation:

You will need to use the phythagoream therom, which is a² + b² = c². Plug the values in for the variables to get 7² + b² = 44², (c would equal the hypothenuse because the hypothenuse is the longest side of the triangle.) Square the values to get 49 + b² = 1936. Subtract 49 from both sides to get b² = 1887, then take the square root of both sides to get b = 43.4 (rounded to the nearest tenth.)

I am really sorry if I'm wrong, but have a good day/night! :)
