Answer:
-59
Step-by-step explanation:
f(x) = -2x - 7 and g(x) = -4x + 6.
f(g(x)) =
Replace x in the function f(x) with g(x)
= -2(-4x+6) -7
= 8x -12 -7
= 8x - 19
Let x = -5
f(g(-5) = 8(-5) -19
= -40 -19
= -59
Answer:2 gallons per hour
Step-by-step explanation:
divide 6 and 3
If each x term corresponds to exactly
one y term, the relation is a function.
In the data set shown here, notice that each x term, 6, -2, 4, and -1 appears only once. This means that each x term corresponds to exactly one y term. So yes, the relation is a function.
Hi, the temperature at the middle of the night was 8.5 degrees.
Average of -2 degrees F and 17 degrees F is 7.5((-2+17)/2)
So 8.5 is the closest.
Hope this helps you.
