-3 (-4 + -x ) = (-4(x) × 2 ) + 6

-3 (-4-x) = (-4x × 2) + 6

-12 + 3x = -8x + 6

3x - 12 = 6 - 8x

add 8x on both sides

11x - 12 = 6

add 12 on both sides

11x = 18

<em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>1</u></em><em><u>/</u></em><em><u>1</u></em><em><u>8</u></em>

Find the two inequalities that define the region on the grid that is not shaded
hoa [83]

Answer:

y 》 2

y > -x + 3

Step-by-step explanation:

Equation of the bold line:

m = (-3/3) = -1

y = -x + 3

Shaded region is below y=2 (dotted)

So, it's defined by y < 2

Also, it's below the bold line

y 《 - x + 3

Everything outside these is not shaded:

y 》2

and y > -x + 3

Which relation is a function
Alenkinab [10]

Answer:

Top left

Step-by-step explanation:


In order for it to be a function, it has to pass the vertical line test.  So draw a line down the middle of the graphs.  If it passes once, then it is a function, if it passes more than once it is not.
