Hello :
2x² = 2
x²=1
x²-1=0
(x-1)(x+1) = 0
x-1=0 or x+1=0
x=1 or x= -1...(answer : <span>B. There are two solutions: -1 and 1 )</span>
Step-by-step explanation:
The answer is 29 degrees because the outer angle is equal to the inner angles, so the equation would be:
G=P+R and if you substitute you get 56=P+27
Solve it and you get:
P=56-27
P=29

Answer: C. (5, -2)
<u>Step-by-step explanation:</u>
Graph each equation:
Equation 1: y < (1/2)x - 3 --> m = (1/2) b = -3, dashed line, shaded below
Equation 2: y > -2x + 6 --> m = -2 b = 6, dashed line, shaded above
or plug the values into the equations. It must be TRUE for both equations:
y < (1/2)x - 3 y > -2x + 6
(7, -8) True False
(2, -3) True False
(5, -2) True True <-- This works!
(4, 1) False True
