Answer:
f(- 2) = - 4
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = (- 2)² + 3(- 2) - 2 = 4 - 6 - 2 = - 4
Value of f(-2) is -4
Given that;
f(x) = x²+3x-2
Find;
Value of f(-2)
Computation:
Given that;
f(x) = x²+3x-2
By putting x = -2
f(-2) = (-2)² + 3(-2) - 2
f(-2) = 4 - 6 - 2
f(-2) = 4 - 8
f(-2) = -4
So, -4 is the correct answer to the given equation.

Solve the equation. 1 2 = 11 2
What is the slope of a line perpendicular to the line whose equation is x-2y=12? Fully reduce your answer
Answer:
First, we need to solve the equation in the problem for y to put it in slope-intercept form so we can determine its slope:
2y−6x=4
2y−6x+6x=6x+4
2y−0=6x+4
2y=6x+4
2y2=6x+42
2y2=(6x2)+(42)
y=3x+2
The slope-intercept form of a linear equation is: y=mx+b
Where m is the slope and b is the y-intercept value.
Therefore the slope of this equation is m=3
A perpendicular line will have a slope (let's call this slope mp) that is the negative inverse of this line. Or, mp=−1m
Substituting gives:
mp=−13

For the function y = f(x) = 3x -5
What is the y intersection
Answer:
The y-intercept is -5.
Step-by-step explanation:
In algebra, "y=" and "f(x)=" is basically the same thing. You don't have to write them both. Also, [tex]y=3x-5[/tex] is in slope-intercept form, which is: [tex]y=mx+b[/tex], where [tex]b[/tex] is the y-intercept. That means "-5" is the y-intercept.

A rate is a ratio that compares
Rate is ratio that compares two quantities of different units.
What is rate?A rate is a special ratio in which the two terms are in different units. Rate can also be defined as the ratio between two quantities of different units
For example, velocity is an example of rate, because it defined by the ratio of distance covered and time.
The unit of distance is metres and the unit of time is second. Therefore ;
velocity = distance /time. Therefore velocity is a rate.
Another example is ; Ade eat 5 mangoes for 20 days. The rate at which Ade eat is
1 day = 5/20
= 1/4 mangoes. This means Ade eats 1/4 mangoes per day.
