Answer:
Step-by-step explanation:
plug y into the first equation:
8x+5y=24
8x+5(-4x)=24
8x-20x=24
-12x=24
x=-24/12
x=-2
then plug x to the second equation
y=-4
y=-4(-2)
y=8
x=-2
y=8
I assume they are lines? If not, then let's just say that they are lengths of lines. If ab = 21 centimeters and bc = 28 centimeters, then it is most likely that the line ac would equal to 49 centimeters. This was obtained through adding the length of two lines since they appear connected by point b.
Step 1: Find the slope of the line. To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 3x – 5y = 9 is m = 3<span>/5. Therefore, the slope of the line parallel to this line would have to be </span>m = 3<span>/5.</span>
Your answer is D . Hope I helped :) !
The answer is going to be 20 because half of 20 is 10
