Answer:
a is still equal to band a
Step-by-step explanation:
a=band b then band b= band c and so on
Multiply each side by x, leaving you with 3-6/10+4, then solve to get -3/14
Hope this helps :)
The line of symmetry is the center/ middle of the parabola where the curve shifts. Since the line of symmetry is at x=2 and the zero is at x= -1, you have the find the difference between the values which is 3. So the other zero is three the right of the line of symmetry at x= 5.
4x +28 and 68 are vertical angles and are equal.
Set them to equal each other to solve for x:
4x +28 = 68
Subtract 28 from each side:
4x = 40
Divide both sides by 4:
x = 40/4
x = 10
