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>
After an hour (4pm to 5pm) the temperature drops 18e⁻⁰˙⁶=9.9℉, so the temperature after an hour will be 68-9.9=58.1℉.
(The change -18e⁻⁰˙⁶ is negative indicating a drop in temperature.)
Answer:
0.2(2 tenths) times 0.3(3 tenths) = 0.06
Step-by-step explanation:
2 times 3 equals 6.
The 6 would have a 0 before it because you are using multiplication. If you were using addition, it would be 0.5(5 tenths) since you are adding tenths.
576 because the triangle in the pyramid would be 216 divided by 2 is 108 since there is 4 triangles to a pyramid you multiply by 4 and that is 432. Then you add the area of the square which is 144 and add that to 432 which makes it 576
