Answer: Here is the explanation. also it it +3y not -3y
Step-by-step explanation:
x+y+4+2y+1=x+3y+5 because
2y+y=3y
so now you have x+3y+4+1
4+1=5
now you have: x+3y+5
if you do not understand, What i am trying to say is, you need to add all of the same things.
The slope of a line parallel to this line is -4/7
And the slope of a line perpendicular is 3/4
See how many 5s there are in 47? There are 9 and also a leftover 2 which is your remainder.<span />
<span>we are given with a swimming pool with dimensions
</span>12-ft-by-15-ft. given that there is a <span>3-ft-wide no-slip surface around it, the new dimensions now become (12+3+3) or 18 ft by (15+3+3) or equal to 21 ft. The perimeter is the sum of the sides of the new rectangle. Perimeter is equal to 18+ 18 + 21 + 21 or equal to 78 feet</span>
Slope : -3/4
Y -intercept (0,5)
