Answer:
D. 15
Step-by-step explanation:
3x-10=2x+5
to solve subtract 2x from both sides
(3x - 2x) - 10 = 2x + 5 - 2x
add 10 to both sides
x -10 + 10 = 5 + 10
x = 15
There are 10*9*8 = 720 possibilities and only one case that would be the 3 digits of the phone number:
P = 1/720
Answer:
To graph the line mark off the 2 points and draw a line through them.
Step-by-step explanation:
The slope = (-2-7) / (-3-0)
= -9/-3
= 3.
The value of b is found using the point-slope form of a line:
y - y1 = m(x - x1)
using m = 3, (x1, y1) = (0, 7):
y - 7 = 3(x - 0)
y = 3x + 7.

This is a parabola, meaning the equation is a quadratic, so it has 2 roots or x-intercepts, keeping in mind that vertex will lie half-way between those intercepts.
so what's the x-value halfway between -3 and 7? yeap, you guessed it, 2.
so the axis of symmetry for this vertical parabola will be at x = 2.
