Answer:
To find the x-intercept of any equation, set the y-value to 0.
Step-by-step explanation:
Example:
y=1x+4
To find x-intercept:
0=1x+4
1. Subtract 4 from both sides
2. Divide both sides by 1
The x-intercept is -4
7. x=3 is the midpoint between the roots. The other root is x = 2*3 -(-5) = 11.
8a) f(x) = (x +3)^2 -49. The vertex is (-3, -49). The roots are -10, 4.
8b) y = (x+4)^2 -1. The vertex is (-4, -1). The roots are -5, -3.
8c) f(x) = 2(x +3)^2 -34. The vertex is (-3, -34). The roots are -3±√17.
Answer:
7
Step-by-step explanation:
20 - 12 = 8
15 - b = 8
-b = 8 - 15
b = 7 ( -ve signs will become +ve)
