Answer:
x=7/4
Step-by-step explanation:
13x-17x+7=0
-4x+7=0
-4x+7-7=0-7
-4x=-7
-4x/-4=-7/-4
x=7/4
Answer:
A
Step-by-step explanation:
If we insert the original coordinates into the problem, we will find the answer.
(2+2, 1-5)
so, once solved
(4, -4)
remember, adding to X means moving the point right, subtracting to X means moving left.
Adding to Y means moving the point up, subtracting to Y means moving down.
7. the formula for octagon is a=2(1+radical2)s^2
s=4
a=about 77.25
8.
Answer:
y+2= -1/5(x+1)
Step-by-step explanation:
if lines are perpendicular their slopes are negative reciprocal
y=mx+b where m is the slope
y=5x-10 has the slope 5 so a perpendicular line will have slope -1/5
equation point slope form
(y-y1) = m(x-x1) where m is slope, and (x1,y1) any point that belongs to the line
y+2= -1/5(x+1)
