Answer:
The perimeter of a rectangle is equal to 2L + 2W, where L = the length of the rectangle and W = the width of the rectangle. So, one equation is
2L + 2W = 60
From the info given in the problem, we also know that L = 4W. Therefore, we can use the Substitution Method to re-write the first equation as:
4W + 2W = 60
You should be able to solve this equation for W. Once you find W, you can then calculate L.
Step-by-step explanation:
So p - $15 = $49 and to solve it subtract 15 from 49 and then you will get your answer
Answer:
Slope = -2
Step-by-step explanation:
x1 y1 x2 y2
(-1 , 9) (2 , 3)
Slope = <u>y2 - y1</u>
x2 - x1
<u>3 - 9 </u>= <u> -6 </u>
2 -(-1) = 3
= -2
After 3 seconds it's been descending for 3 seconds at a rate of 2 feet per second. So it's gone down 6 feet, and now it's at a height of 67. So it started off at 73.
<span>Its height after x seconds is 73 - 2x. (73 to start off with, minus 2 feet per second that's passed.) </span>
<span>After 8 seconds it will be at a height of 73 - 2*8 = 73 - 16 = 57.</span>
