Answer:
Solve one of the equations for y, take that answer and plug into the second equation in place of y. Then solve for x.
Step-by-step explanation:
Need equations if you want actual answer
Answer:
y=-5/4 + -1.25
Step-by-step explanation:
y1 - y2 over x1 -x2
5- -5 =10
-5-3 =-8
simplify: -10/8 which is -5/4 *THAT IS YOUR SLOPE*
Now to find the y intercept pick a point. I chose (-5,5) and plug in for y=mx+b
y will be 5 ; m is your slope so -5/4 ; x is -5 and we don't have out b yet.
5=-5/4(-5) + b
multiply -5/4 and -5 = 6.25
then just subtract -5 and -6.25 = -1.25 which is your y intercept
y= -5/4 + -1.25
Let x represent the number of minutes and y the cost. Then
y - 0.85 = (1.10 - 0.85)/(10 - 5) (x - 5)
y - 0.85 = 0.25/5 (x - 5) = 1/20 (x - 5) = 1/20 x - 1/4
y = 0.05x - 0.25 + 0.85 = 0.05x + 0.6
y = 0.05x + 0.6
The cost of 25 minutes = 0.05(25) + 0.6 = 1.25 + 0.6 = $1.85
0.17×100= 17
So it's 17 meters.
Hope this helps! :)

Answer:</h3>
<u>Perimeter of rectangular garden = 2(l + b)</u>
- 2(y + 2 + 4y - 1)
- 2y + 4 + 8y - 2
- 10y + 2.
<u>Hence, perimeter of given garden is 10y + 2</u>.
