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

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

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

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

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

4(x+1)/(5-4x)​

Respuesta :

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.

The expressions are equal to 0 when x = -1 will be 4(x + 1)/(4x + 5), 4(x - (-1))/(4x + 5), and 4(x + 1)/(5 - 4x)​. Then the correct options are A, C, and E.

What is the value of the expression?

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The expressions are equal to 0 when x = -1 will be

Check all that apply.

A.  4 (x + 1)/(4x + 5) = 4 (-1 + 1)/(4 × -1 + 5) = 0

B.  4 (x - 1)/(5 - 4x) = 4 (- 1 - 1)/(5 - 4 × -1) = -8/9

C.  4 (x - (-1))/(4x + 5) = 4 (-1 + 1)/(4 × -1 + 5) = 0

D.  4 (x + (-1))/(4x + 5) = 4 (-1 - 1)/(4 × -1 + 5) = 8

E.  4 (x + 1)/(5 - 4x)​ = 4 (-1 + 1)/(5 - 4 × -1)​ = 0

The expressions are equal to 0 when x = -1 will be 4(x+1)/(4x+5), 4(x-(-1))/(4x+5), and 4(x+1)/(5-4x)​.

Then the correct options are A, C, and E.
