For x intercepts, plug in 0 for y.
0 = (x^2) - 2x - 35
*factoring* = (x-7)(x+5)
x intercepts = 7,-5
As for the vertex, you can use the equation -b/2a for the x-coordinate of the vertex
so,
x = -b/2a = -(-2)/2 = 1
then just find the y value by plugging it back in to the equation.
y = ((1)^2) - 2(1) - 35
= -36
so, vertex is at (1,-36)
Answer:
The Check that hasn't been cleared yet is for $372.15.
Step-by-step explanation:
168.48+ 168.93+ 177.78+ 177.93= 693.12
887.79- 693.12= 194.67
1,065.27- 887.79= 177.48
194.67+ 177.48= 372.15
To check your answer:
372.15+ 693.12= 1,065.27
Hope this helped you!! (:
