Answer:

x = 4

Step-by-step explanation:

If A is parallel to B, therefore,

9x + 4 = 5x + 20 (alternate interior angles are congruent)

9x + 4 - 5x = 5x + 20 - 5x (subtraction property of equality)

4x + 4 = 20

4x + 4 - 4 = 20 - 4 (subtraction property of equality)

4x = 16

4x/4 = 16/4 (division property of equality)

x = 4

Answer:

Step-by-step explanation:

In ordered pairs (a,b) a is the x value and b is a y value.

if we have 3x+y=6

if x=0, y=6 --> (0,6)

if y=0, x=2 -->(2,0)

if x=3, y=-3--> (3, -3)

if x=6, y= -12 --->(6, -12)

if x=6, y= -9 ---> (5, -9)

Solve: -25 < x + 20 < 25

denis23 [38]

Answer:

-45 < x < 5 (see graph below)

Step-by-step explanation:

to isolate x by itself, subtract 20 from all three terms of the equation:

$(-25-20)$

once you finish subtracting 20, x should be by itself, making the equation graphable:

$-45 < x < 5$

since x is not equal to -45 or 25, the graph line endings have open circles.
