-2 = 39x ? Are you sure this is right? I'm willing to help!
Answer:
Step-by-step explanation:
191.2 = 2.3L +65.5
191.2 - 65.5 = 2.3L {Subtract 65.5 from both sides}
125.7= 2.3L
L = 125.7/2.3
L = 54.65
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)
