Answer:
The original price of a skateboard is $64
Step-by-step explanation:
Let
x ----> the original price of a skateboard
y ----> the new price of a skateboard
we know that
The linear equation that represent this problem is equal to
y=x-15 ----> equation A
y=49 ---> equation B
substitute equation B in equation A and solve for x
49=x-15
Adds 15 both sides
49+15=x
64=x
Rewrite
x=$64

H=7
To convert this to vertex form, we must complete the square. This equation is in the form f(x)=ax²+bx+c. To complete the square we take half of b and square it:
(-14/2)²=(-7)²=49
This tells us what to add to the function. We must also subtract it from the function, however, in order to preserve equality:
p(x) = x²-14x+49+29-49
p(x) = (x-7)²-20
Now that it is in vertex form, we can see that the value of h is 7.
Answer: See below
Explanation:
(f • g)(-7) = [-8(-7) -6](-7+8)
= (56 - 6)(1)
= (50)(1) = 50
