Dimas [21]3 years ago
6 0

Step-by-step explanation:

-6 ( x - 2y )                          ( -12x ) / ( -2 )

-6 ( -3 - 2*-5 )                     -12 / -2 = 6

-6 ( -3 + 10)                          6x

-6 ( 7 )

-42

Olin [163]

Answer:

y=-4x+2

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

Step 1

Find the slope m

Let

A(1,-2),B(2.-6)

m=(-6+2)/(2-1)=-4

Step 2

Find the value of b

we have

m=-4

A(1,-2)

substitute in the equation of the line

y=mx+b

-2=(-4)(1)+b

-2=-4+b

b=2

The equation in slope intercept form is equal to

y=-4x+2

Solve the equation 4z^2 + 4z -9 = 0 by completeing the square<br><br><br>​
nasty-shy [4]

Answer:

z=(sqrt(10)-1)/2 or z= -(sqrt(10)-1)//2

Step-by-step explanation:

To complete the square, the last term has to be 1. So adding 10 to both sides, we get:

4z^2+4z+1 = 10

Since 4z^2+4z+1=(2z+1)^2,

(2z+1)^2 = 10.

Taking the square root of both sides, we get

2z+1=sqrt(10) or 2z+1=-sqrt(10)

So z=(sqrt(10)-1)/2 or z= -(sqrt(10)-1)//2

Charlize and Camille solved the equation 4x – 2y = 8 for y. Their work is shown
Aloiza [94]

Answer:

The answer to your question is below

Step-by-step explanation:

Equation 4x - 2y = 8 solve for y

First, pass 4x to the right side                -2y = -4x + 8

Pass -2 to the right side                             y = -4/-2 x  + 8 /-2

Simplify                                                        y = 2x -4 or    y = -4 + 2x

I can not see clearly the work of Charlize and Camille, but the one that has the answer shown above is correct.
