D. x = 3

You can get this by turning these into equations

-3x + 6 = 2x - 9

Then solve.

Answer:

value of x=3

Step-by-step explanation:

Use the model to find the question and solve for x

-x  -x  -x represents -3x

1  1 1 1 1 1 represents 6

x  and x represents 2x

-1  -1  -1     -1     -1    -1  -1    -1    -1   represents -9

The equation becomes

-3x + 6 = 2x -9

Subtract 2x on both side

-5x +6 = -9

subtract 6 on both sides

-5x= -15

divide by -5

x= 3

X=7




Explanation:

A triangle equals 180°, and they gave us one length already, and it says the one arm of the triangle is equal to the other so we know that the third angle is going to be the same as the second angle.


180=90+(6x+3)+(6x+3)
Combine like terms
180=96+12x
Subtract 96 from both sides
84=12x
Divide 12 by both sides
7=x


Now check it,

90+(6*7+3)+(6*7+3)
90+(45)+(45) =180

What would you have to do to make the line y = 2x -7 steeper on the coordinate plane?
ValentinkaMS [17]
The slope, if increased, would make the line y=2x-7 steeper. If you were to increase the y intercept, you would just move the line, not tilt it. Suggest changing it to 4x-7 = y or 8x-7= y, if you increase the slope, it'll make it steeper.

what is an equation of a line that passes through the point (-4,-6) and is perpendicular to the line 2x-y=6
igor_vitrenko [27]

Answer:

Answer:y=2/3x-10/3

- 4/-6 is 4/6 so m is 4/6 then fill in the x and y variables in y=Mx+b solve for b then start plotting the equation of the line to check and you get your answer

I think this is the answer you might need to check again with more people
