What is the slope of a line perpendicular to the line who’s equation is x-y=5 fully reduce your answer
Yakvenalex [24]

Answer:

-1

Step-by-step explanation:

Use the slope intercept formula(y=mx+b) to find the slope of a line.

First, you will want to put everything into it's proper order, so you will get -y=-x+5.

You cannot have a negative y, so divide everything by -1 and you will get y=x-5.

1 is the slope. Now that you know that, you will want to find the reciprocal. To find the reciprocal, you will need to swap the numerator and the denominator and then swap it's sign, whether that is positive or negative..

The reciprocal of 1 is -1. -1 is the slope of the perpendicular line

Juvi is baking oatmeal raisin cookies and fudge brownies! To make 4 batches of brownies, Juvi needs 2/3 of a cup of sugar. She a
dsp73

We can add the fractions together to compare with how much sugar she needs.

\frac{1}{2}+\frac{2}{5}=\frac{5}{10}+\frac{4}{5}=\frac{9}{10}

So Juvi has \frac{9}{10} cups of sugar.

She needs \frac{2}{3} cups, so let's make the denominators the same and compare.

\frac{2}{3}=\frac{20}{30}

\frac{9}{10}=\frac{27}{30}

Since \frac{27}{30} > \frac{20}{30}, she has enough sugar to make 4 batches of brownies.

Hope this helps.

頑張って!
