5x – 2(x + 7) = -5

mutiply the bracket by -2

(-2)(x)= -2x

(-2)(7)= -14

5x-2x-14=-5

3x-14= -5

move -14 to the other side, sign changes from -14 to +14

3x-14+14= -5+14

3x= 9

divide by 3 for both sides

3x/3= 9/3

x= 3

Answer: x= 3

Komok [63]

Answer:

i think the answer is (B)

Step-by-step explanation:

The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.

Put the following equation of a line into slope-intercept form, simplifying all
Rudik [331]

Answer:

y=-3x-3

Step-by-step explanation:

9x+3y=-9

This is currently in standard form, or ax+by=c.

To get it to slope-intercept form, (y=mx+b) first subtract 9x to both sides.

3y=-9x-9

Divide both sides by 3.

y=-3x-3
