Answer:
Option A is the answer.
Step-by-step explanation:
We have been given the ordered pairs.
The function is a representation
For a mapping to be a function there should always be a unique value of y for different values of x.
So the mapping :
(-4,-2) (-1,3) (0,3) (5,-6)
3 has two different values hence not a function.
Therefore, Option A is the answer.
I believe that f(x) = 3(x-1). From the distance between the f(x) values you can infer that the factor in front of x must be 3. Then for x=0 the value is -3. So f(x) = 3x - 3 or 3(x-1).
Well this is pretty simple
for the area we need to use the formula A=3.14*radius*radius
so we just plug it in and we get 3.14*8*8 which is 200.96 centimeters squared
for circumference we need to do C=3.14*diameter
to find the diamter we need to do 8 (radius) x 2 which is 16
plugging it in that would be 3.14 * 16 which is 50.24
So in this case the the area is 200.96 and the circumference is 50.24 :)
To factor a cube (a^3-b^3) = (a-b)(a^2+ab+b^2)
8 is the cube of 2
r^3 is the cube of r.
So, a is 2 and b is r
(2-r)(2^2+2r+r^2)
(2-r)(4+2r+r^2)
Answer:
x≥4
Step-by-step explanation:
move constant to the right
2x≥17-9
Subtract 17-9
then you should have 2x≥8
Divide both sides of the inequality by 2
and you should have your answer of x≥4
Hope this helps!
