Answer:
Midpoint coordinates are 
Step-by-step explanation:
The Coordinates of R = (-8,3)
The Coordinates of S = (9, -7)
Let M be the mid point of M and its coordinates by (x,y)
Now, by mid point formula,
⇒
So, the midpoint coordinates are
Answer:
$122.50
Step-by-step explanation:
Sale Price: $70
Percent off: 75%
First, find 75% of 70.
To do so, you must change the percent to a decimal (75% to .75) and multiply it by 70.
.75 x 70 = 52.5
52.5 is the amount of money that was taken off the original price, so in order to find that, you must add it to the sale price.
52.5 + 70 = 122.5
So the original price was $122.50
divide second equation by -3
3x+2y=1
other equatin is
3x+2y=1
since same equation, they are same line and lines are infinite so infinite solutions is answe
