Ksivusya [100]

The value of y in $-3 = 7\left(y-\dfrac97\right)$ is 6/7

<h3>How to solve for y?</h3>

The equation is given as:

$-3 = 7\left(y-\dfrac97\right)$

Open the bracket

-3 = 7y - 9

Add 9 to both sides of the equation

7y = 6

Divide both sides by 7

y= 6/7

Hence, the value of y in $-3 = 7\left(y-\dfrac97\right)$ is 6/7

Which expressions are equal to 0 when x=-1? Check all that apply.

Reptile [31]

Answer:

4(x+1)/(4x+5)

4(x+1)/(5-4x)

4(x-(-1))/(4x+5)

Step-by-step explanation:

The numerators in the fractions must equal to 0, or else the expressions won’t have the result of 0.

4(x+1)

4(-1+1)

4(0)

= 0

4(x-(-1))

4(-1-(-1))

4(-1+1)

4(0)

= 0

The expressions with the numerator as 0 have the result of 0.
