Answer:
x=-7.88
y=-32.35
the point answer would be (-7.88 , -32.35)
Step-by-step explanation:
First step is to multiply 3x+y=-56 by 4 and you get 12x+4y=-224
Then add each equation together to eliminate y from each equation. You get 17x=-134
Then find divide that equation by 17. You would get x=-7.88
Then plug -7.88 into one of the original equations for x. 5(-7.88)-4y=90 And from that you get -39.4-4y=90
Then isolate the y variable. You would get -4y=129.4
Then divide by -4 and get y=-32.35
<span>A proportion is two ratios that have been set equal to each other;
a proportion is an equation that can be solved.
When I say that a proportion is two ratios that are equal to each other, I mean this in the sense of two fractions being equal to each other.
For instance, 5/10 equals 1/2.</span>
Answer:
n = 7
Step-by-step explanation:
3(n - 4) = 9
3n - 12 = 9
3n = 9 + 12
3n = 21
n = 21 ÷ 3
n = 7
Answer:
C
Show your work:
A perpendicular line has a negative reciprocal slope so 2/3 becomes -3/2, then substitute your point (-6,4) and you get letter C
