Answer:
-n← 2 2/3
Step-by-step explanation:
first combine like terms, and then simplify
A = 15 3 x 15 + 9 = 54 keep up the good work!
Perpendicular has slope that multiplies to -1
the slope for ax+by=c is -a/b
-1x+2y=4
slope=-(-1)/2=1/2
1/2 times what=-1?
-2
y=mx+b
m=slope
we need slope is -2
y=-2x+b
find b
given
(-2,1)
(x,y)
x=-2 and y=1 is a solution
1=-2(-2)+b
1=4+b
mius 4 both sides
-3=b
y=-2x-3 is equation
first one
Answer: 46 degrees
Step-by-step explanation: First you need to find the value of the vertical angle which is 180-(85+53) which is 42 degrees. Since vertical angles are congruent, you can say that 180-(42+92) is equal to x. When you solve it, you get x=46 which is your answer
