the answer is 
subtract 6x on both sides → 
divide both sides by -2y → 
4x+16=6x
16=2x
8=x
And 11y+6x=180 (line)
11y+6(8)=180
11y+48=180
11y=132
Y=12
If the line segment is perpendicular to a line with the slope of -4, that means the line segment has a slope of 1/4.
First let's make an equation for the line segment using the slope of 1/4 and the point at (2,6) to find the final piece, the y-intercept
y = mx + b
6 = 1/4(2) + b
6 = 2/4 + b
24/4 = 2/4 + b
22/4 = b
y = 1/4 x + 22/4
6 = 1/4(2) + 22/4
6 = 2/4 + 22/4
6 = 24/4
6 = 6 <-- proves that this equation is correct
Now you may plug in the x to find y. ( 8 , y )
y = 1/4(8) + 22/4
y = 8/4 + 22/4
y = 30/4 = 15/2 = 7.5
Answer : 12.8
Step-by-step explanation: if u round the 7 it is going to be eight because it is bigger than four
No, it’ll be just 49 not negative 49. Because you times they by it’s self and the negatives cancel eachother !
