Answer:
Option C.
Step-by-step explanation:
The given table represents a linear function.
If a linear is graphed by a line and the line passes through two points (x, y) and (x', y'), slope of the line is calculated by the formula
Slope =
Since line passes through two points (-2, -2) and (-1, 1)
Therefore, slope =
=
= 3
Slope of the line will be 3.

Answer:
x = 4 or x = -3/2
Step-by-step explanation:
To simplify and solve this, let's use the quadratic formula.
So the format of a quadratic equation is supposed look like this:
Let's find a, b, c:
- a is the coefficient of x^2
- b is the coefficient of x
- c is the constant term
Now let's solve the equation.
Let's solve your equation step-by-step.
2x^2−5x−12=0
For this equation: a=2, b=-5, c=-12
2x^2+−5x+−12=0
Step 1: Use quadratic formula with a=2, b=-5, c=-12.
