Answer:

Step-by-step explanation:

First take the y values. They increase 20 so that is going to be your rise. Then take your x values, that also increase by 10. That is your run. Your slope is 20/10 which simplifies to 2.

Answer:

The slope is 2

Step-by-step explanation:

The slope, when given two points, is found from

m = (y2-y1)/(x2-x1)

= (15--5)/(3--7)

= (15+5)/(3+7)

=20/10

A rectangle of perimeter 74 cm is 7cm longer than it is wide. what is the length of each side?

Mumz [18]

I assume that you mean: the length is 7cm more than the width, and the perimeter is 74 cm.

If so, we can write down the following system, where l and w represent, respectively, the length and the width:

$\begin{cases}l=w+7\\2(l+w)=74\end{cases} \iff \begin{cases}l=w+7\\l+w=37\end{cases} \iff \begin{cases}l=w+7\\(w+7)+w=37\end{cases}$

We can easily solve the second equation:

$(w+7)+w=37 \iff 2w+7=37 \iff 2w=30 \iff w=15$

And finally solve for the length:

$l=w+7=15+7=22$

Ray’s weight increased by 11% in the last two years. If he gained 16.5 pounds, what was his weight two years ago?

xz_007 [3.2K]

11% = 16.5
1% = 16.5 / 11
= 1.5
100% = 1.5 * 100
= 150. His weight two years ago was 150 pounds.
