Answer:

x = 90

Step-by-step explanation:

We use the Definition of Corresponding Angles to help us solve for <em>x</em>:

∠1 = ∠4

Step 1: Write out equation

3x - 160 = x + 20

Step 2: Solve for <em>x</em>

2x - 160 = 20

2x = 180

x = 90

Answer:

a) (2, 8)  

Step-by-step explanation:

The easiest way is to insert the coordinates into the inequality.

a) (2, 8)

\begin{array}{rcl}4(2) - 2(8) & < & -2\\8 - 16 & < & -2\\-8 &< & -2\\\end{array}\\\textbf{TRUE}

b) (0, 1)

\begin{array}{rcl}4(0) - 2(1) & < & -2\\0 - 2 & < & -2\\-2 &< & -2\\\end{array}\\\text{False}

c) (3, 7)

\begin{array}{rcl}4(3) - 2(7) & < & -2\\12 - 14 & < & -2\\-2 &< & -2\\\end{array}\\\text{False}

d) (5, 8)

\begin{array}{rcl}4(5) - 2(8) & < & -2\\20 - 16 & < & -2\\4 &< & -2\\\end{array}\\\text{False}

You could also plot the inequality and test the points. You would get a graph like the one below. Point (2, 8) is the only one that satisfies the inequality. Points (0, 1) and (3, 7) do not satisfy the inequality because they are on a dashed line.

inna [77]

Answer:

x=2

Step-by-step explanation:

y=-7x+13

y=-1

plug in -1 for y in the first problem.

-1=-7x+13

subtract 13 by both sides

-14=-7x

divide both sides by -7 to isolate x

2=x

hope that helped have a good day
