Answer:
The y-intercept is (0,-12).
Step-by-step explanation:
Given equation is 
.
Now question says to find the y-intercept of the given parabola .
We know that y-intercept means the y-value when x-value equals 0
so let's plug x=0 into given equation then solve that for y.
Hence the y-intercept is (0,-12).
An outside angle of a triangle is equal to the sum of the two opposite inside angles.
Using the information in the picture, 132 is an outside angle and x and (3x-24) are the two opposite inside angles.
Setting up the equation you would have: 132 = x + (3x-24)
Now solve for x:
132 = x + (3x-24)
Simplify:
132 = 4x -24
Add 24 to both sides:
156 = 4x
Divide both sides by 4:
x = 156/4
x = 39
Answer:
B.
Step-by-step explanation: The value of a ratio is the quotient of the two quantities in the ratio.
So, for number 3, its 2. and for number 4 its also 2
As shown:
Angle C = Angle f = 127
The length of fe = the length of CA = 2 units
Angle E = Angle A = 40
So, triangle ABC = triangle EDF by ASA
The answer is option 2
