Answer: 39.13
Step-by-step explanation:
:)
y varies inversely with x.
Example:
If we multiply x by 2 we need to divide y by 2 too.
So,
If y = 16 and x = 1/2, find y when x = 32
Lets see, from 1/2 to 32 e need to multiply 1/2 by 64, right? So let's divide 16 by 64.
16/64 = 8/32 = 4/16 = 2/8 = 1/4
So we can say that:
If y = 16 when x = 1/2, y = 1/4 when x = 32.
The solution to the problem is as follows:
5x^2 + 9x - 2 / x^2 + 12x + 20 multiply x^2 + 17x + 70 / 15x - 3
<span>
=[(5x-1)(x+2)]/[(x+2)(x+10)] multiply [(x+7)(x+10)]/[3(5x-1)] </span>
<span>
=(x+7)/3

Answer:
d. vertical line
Step-by-step explanation:
A line with an undefined slope is a vertical line
Slope is the change in y over the change in x
When the slope is undefined, it means that the x does not change, which is a vertical line
