Answer:y=2/3x
Step-by-step explanation:
y=2x-2y
combine like terms
y+2y=2x
y=1
so 1y+2y=3y
3y=2x
divide 3 on both sides 3y =2x
Answer:
Step-by-step explanation:
Yes it is a quadratic equation
5x^2 + 40x = -7
5x^2 + 40x + 7 = 0
a = 5
b = 40
c = 7
-40/10 <u>+</u> (sqrt(1600 - 4(5)(7)))/10
-4 <u>+</u> (sqrt(1600-160))/10
-4 <u>+</u> (sqrt(1440))/10
-4 <u>+</u> 12(sqrt(10))/10
-4 <u>+</u> 6/5(sqrt(10))
