Can someone help me with this? I cannot figure it out

Mathematics

Answer:

Step-by-step explanation:

To graph by hand I would first convert both equations into y=mx+b.

We start with:

\left \{ {{2x-2y=4} \atop {x+2y=8}} \right.

Solve for y for 2x-2y=4

2x+2y=4\\2y=4-2x\\y=2-x

Solve for y for x+2y=8

x+2y=8\\2y=8-x\\y=4-\frac{x}{2}

Giving the new but equal system of equations:

\left \{ {{y=2x-x} \atop {y=4-\frac{x}{2} }} \right.

From this point on you can graph the two functions to find where the two lines intersect, thats your solution.

I've gone ahead and graphed it on desmos for you

Rozalie spent $26 at a parking garage in downtown Orlando. The garage charged a base free of $7.50 for the first hour and a hour
bagirrra123 [75]
ANSWER : Rozalie spent 6.73 hours at the garage


rate of change = $2.75
base fee = $7.50

set up your equation:
2.75h + 7.5 = 26
($2.75/hour plus the base fee of $7.50 equals the total amount spent, $26)

Now just solve for h

2.75h + 7.5 = 26
2.75h = 18.5
h = 6.727273 (rounded)
h = 6.73

So the answer would be Rozalie spent about 6.73 hours at the garage.
