The answer is D) 1/4

We draw the triangle and we notice triangle ABC is similar to DBE so all the sides will be in proportion.

Since AC is 4 times longer than DE, all the sides of triangle ABC will be 4 times longer.

Then if the perimeter of ABC was lets say 8, DBE would have a perimeter of 2.

D is the answer :)

If -3m + 1 > 7, which of the following is a solution set for m?

Papessa [141]

ANSWER

m < -2

EXPLANATION

We want to find the solution set for m in:

$-3m+1>7$

First, collect like terms:

$\begin{gathered} -3m>7-1 \\ -3m>6 \end{gathered}$

Now, divide both sides by -3. When you divide an inequality by a negative number, <em>the sign changes direction</em>:

$\begin{gathered} \frac{-3m}{-3}>\frac{6}{-3} \\ m$

This means that all values of m must be less than -2.

<em>None of the options contains the correct solution set.</em>
