The solution of the set of equation is
x=6.217
y=0.132
<u>Step-by-step explanation:</u>
given the set of equations
0.7x-y=4.22(1)
5-0.8x=0.2y
-0.8x-0.2y=-5 (2)
multiply (1) and(2) by 10
7x-10y=42.2(3)
-8x-2y=-50(4)
solve (3) and (4) using elimination method
⇒-40x-10y=-250(5)
(5)-(3)
-47x=-292.2
x=6.217
substituting value of x in 3
we get y=0.132
Answer:9
Step-by-step explanation:pp
Hi there!
Since the slope of a lime that is parallel is always the same, the answer is a. -1.
Since the slope of this equation is -1, the slope of any other parallel line is the same (or else the lines would intersect and not new parallel anymore).
Hope this helps!
