Answer:
y = 112°
Step-by-step explanation:
The adjacent angle to 68° on the line RS are supplementary, thus
adjacent angle = 180° - 68° = 112°
y and the adjacent angle are corresponding and congruent, thus
y = 112°
Answer:
18
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
Answer:
it is 8.1
Step-by-step explanation:
if u see u round over or add 1 to the number if the number that is next to the number ur rounding is 5 or higher. and u do nothing when it is less than 5.
the tenth place is where the the zero is 0.0
and the number after is 6, so it is greater than 5, so it increases
Answer:
( x+1)^2 = 4
Step-by-step explanation:
x^2+2x-3=0
Add 3 to each side
x^2 +2x = 3
Take the coefficient of x
2
Divide by 2
2/2 =1
Square it
1^2 =1
Add to each side
x^2 +2x = 3
x^2 + 2x+1 = 3+1
( x+1)^2 = 4
Take the square root of each side
x+1 = ±2
Subtract 1 from each side
x+1-1 = -1 ±2
x = -1+2 x = -1-2
x =1 x = -3
A is the only option so that is the answer, i guess.
