25/8 to get fraction from 3 1/8 3x8+1 over 8
Answer: x° = 77°
Step-by-step explanation:
x + 103 = 180
x = 180 - 103
x = 77°
also by properties:
x° = 42° + 35° = 77°
Hello from MrBillDoesMath!
Answer:
(3,6) is not a point of intersection of the lines.
Discussion:
Let's check if the supposed point of intersection, (3,6), is on both lines. Start by substituting x = 3 and y = 6 in the equation y = 4x -2. This gives
y = 4x - 2
6 = 4(3) - 2 = 12 -2 = 10
6 does not equal ten so the supposed point of intersection doesn't even lie on one of the lines! Hence (3,6) is not a point of intersection of the lines.
Thank you,
MrB
Answer:
The answer is that the vertex is 5.
Look at where the red line crosses/ touches the X axis. This will give you the zeros.
It crosses at -1, it touches at 1 and crosses again at 3
This means the zeros are -1, 1 and 3
So you now you need to have (x+1) (x-3) and (x-1) as factors.
This makes the answer: f(x) = (x − 1)2(x + 1)(x − 3)
