The model below represents 4 x + (negative 4) = negative 2 x + 8.

ikadub [295]

Answer:

x = 2

Step-by-step explanation:

4 x + (negative 4) = negative 2 x + 8

4x + (-4) = - 2x + 8

4x - 4 = - 2x + 8

4x + 2x = 8 + 4

6x = 12

$x = \frac{12}{6} \\ \\ x = 2$

1. 2x = 2 - 9<br> 21y = 4 - 6x

mina [271]

2x=2-9

21y=4-6x

2x=-7

6x=4-21y

x=-7/2

6(-7/2)=4-21y

-21=4-21y

-21-4=-21y

-25=-21y

y=-25/-21

:.y=1 4/21.

Let a= x^2 +4. Rewrite the following equation in terms of a and set it equal to zero.

swat32

Answer:

C and G

Step-by-step explanation:

(x^2+4)^2+32=12x^2+48 is written as $(x^2+4)^2+32=12x^2+48$ .

We can simplify the expression using the term a by replacing x^2 + 4 with a.

$(x^2+4)^2+32=12x^2+48\\(x^2+4)^2+32=12(x^2+4)\\a^2 + 32 = 12a\\a^2 - 12a + 32 = 0$

This factors into (a-4)(a-8). Solve by setting each factor equal to 0 and solve for a.

a-4 = 0 a=4

a-8=0 a=8
