If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to

.
Remember that an equation

represents a line with slope

and y-intercept

. Since both equations given have a slope of -2, but have different y-intercepts, they are
parallel.
Answer:
Step-by-step explanation:
X=8.50
y=9.50
Substitute 4 for m and 6 for n
Y= 4(3+2(6))
Y= 4(3+12)
Y=4(15)
Y=60
Answer:
357_²
Step-by-step explanation:
find the area of the cut out triangle
20 * 21 = 240
240/2 = 210
find the over all area
21 * 27 = 567
subtract the missing piece
567 - 210 = 357
