To know if p = -1 is a possible solution to <span>6(p – 4) = -30p, plug in -1 for p and see if the equation is true.

</span><span>6(p – 4) = -30p
</span><span>6(-1 – 4) = -30(-1)

</span>6(-1 – 4) = -30(-1)<span>
Solve the parentheses.
-1 - 4 = -5

</span>6(-5) = -30(-1)
Multiply.
6 • -5 = -30
-30 • -1 = 30

-30 = 30
This is not true, so p = -1 is NOT a possible solution for the <span>equation 6(p – 4) = -30p.

Hope this helps!</span>

A certain highway has a 7% grade. how many feet does it rise in a horizontal distance of 1 mile? (1 mile = 5280 feet. round your
pentagon [3]
For this case we have the following relationship:
 (x / 5280) = (7/100)
 From this relationship we must clear the value of x.
 Clearing we have:
 x = (7/100) * (5280)
 Calculating we have:
 x = 0.07 * 5280
 x = 369.6 feet

Determine whether these two functions are inverses. ​
11Alexandr11 [23.1K]

Answer:

No The reactions are not inverses to each other

Step-by-step explanation:

f(x) = 3x + 27

Let f(x) be y

y= 3x+27

subtracting 27 on both sides

3x = y - 27

x= (y-27)/3

= y/3 - 9

inverse function is x/3 -9 not x/3 + 9

Therefore, not an inverse

Gwar [14]

Answer with explanation:

Amount charged by Home Improvement Store for first day=$ 45

Amount charged per day after first day = $ 22

y= Total cost

x=Number of days Rented

Writing the above statement in terms of function

→y=1×$45 +(x-1)×$22

→→Total amount charged(y)=45+22x-22

→→→y=22x+23

is, the required function.
