Answer:

(-3,-2)

Step-by-step explanation:

y = 2x+4

y=3x+7

substitute (3x+7) in for y in the first equation.

3x+7 = 2x+4

subtract 2x from both sides

x+7=4

subtract 7 from both sides.

x = -3

plug -3 in for x in either equation to get y.

y= 2(-3) + 4

y = -2

Which graph shows the solution to the inequality -3x-7x<20
hjlf
A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.

To solve this, you will combine like terms first:

-3x-7x < 20
-10x < 20

Divide both sides by -10:
-10x/-10 < 20/-10

When you divide an inequality by a negative number, you flip the inequality symbol:

x > -2
