Step-by-step explanation:
Answer:
x = 147/5 and y = 78
Step-by-step explanation:
First solve by substitution and put 78 into y in -5x + 2y = 9 so you get 147/5
then plug 147/5 into x and find y
Answer:
x = 28
Step-by-step explanation:
The ratios of corresponding sides are equal, that is
=
( cross- multiply )
8(x - 7) = 168 ( divide both sides by 8 )
x - 7 = 21 ( add 7 to both sides )
x = 28
Answer:
y=-4/1x-13
Step-by-step explanation:
5-1/2-3
5-1 ( 4)
2-3 (-1)
y=-4/1x+b
5=-4/1(2)+b
5=-8+b
b=-13
y=-4/1x-13
Hope this helped, have a Wonderful Day!!
