4x-2y&lt;-2<br><br>a) (2,8) b) (0,1) c) (3,7) d) (5,8)​
amm1812

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.

Wade was asked to solve this inequality:
frozen [14]

Answer:

The correct option is Option A: Yes, that is the correct step

Step-by-step explanation:

Wane was asked to solve the inequality \large \frac{x}{3}\ge11

He decides that he needs to multiply both sides by 3.

We need to tell if the step is correct?

So, solving the inequality

\frac{x}{3}\ge11

We need to multiply both sides by 3, to get value of x i.e.

\frac{x}{3}*3\ge11*3\\x\geq 33

So, Wanes step is correct.

The correct option is Option A: Yes, that is the correct step
