In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7

NeX [460]

Answer:

Add 7 to both sides

Step-by-step explanation:

The equation has to be just x = y

There cannot be another number on the same side as the variable

Now that we did that, the equation is 9x = 0

x = 0

Well, that was easy lol

Answer:

A p

Step-by-step explanation:

We have

$12x {}^{ - 3} y {}^{ - 1}$

Remeber that

$x {}^{ - n} = \frac{1}{x {}^{n} }$

$12 \frac{1}{x {}^{3} } \frac{1}{y {}^{1} }$

Now, plug in

So now we plug in -1 for x and 5 for y

$12 \frac{1}{ { - 1}^{3} } \frac{1}{5 {}^{1} }$

Simplify

$- \frac{12}{5}$

A is the answer.

7) If x-2 is a factor of P(x)= x^2-5x+a then find the value of a

ycow [4]

Answer:

a = 6

Step-by-step explanation:

Given that (x - 2) is a factor of P(x) , then P(2) = 0 , that is

P(2) = 2² - 5(2) + a = 0 , so

4 - 10 + a = 0

- 6 + a = 0 ( add 6 to both sides )

a = 6
