Hiya!

When there are 2 negatives together, the (-) sign changes into a (+) sign.

-7 - (-2.5) ⇒ -7 + 2.5

Your answer is D. -7 + 2.5

(-7 + 2.5 = -5.5)

Hi!

Two negatives make a positive, so this can be rewritten as
-7+2.5

The answer is D. -7+2.5

Hope this helps! :)

Help pls look at the picture

Answer:

Option A: $-\frac{4}{3}$ is the correct answer.

Step-by-step explanation:

Given that:

Slope of the line = $\frac{3}{4}$

Let,

m be the slope of the line perpendicular to the line with slope $\frac{3}{4}$

We know that,

The product of slopes of two perpendicular lines is equals to -1.

Therefore,

$\frac{3}{4}.m=-1\\$

Multiplying both sides by $\frac{4}{3}$

$\frac{4}{3}*\frac{3}{4}m=-1*\frac{4}{3}\\$

m = $-\frac{4}{3}$

$-\frac{4}{3}$ is the slope of the line perpendicular to the line having slope $\frac{3}{4}$

Hence,

Option A: $-\frac{4}{3}$ is the correct answer.
