Answer:
the corresponding point for the function f(x) − 4 is (0,-9)
<u>Step by Step Explanation --</u>
Given that (0, -5) is on the graph of f(x),
WE need to find the corresponding point for the function f(-4x}
f(x) means the output y
f(x)-4 means subtract 4 from the output y
In the given point (0, 5) , x is 0 and y is -5
To get the corresponding point we subtact 4 from y
that is [-5]- 4 = -9
the corresponding point for the function f(x) − 4 is (-3,1)
Step-by-step explanation:
Okay so in order to find your slope you're going to need to label your first set of coordinates! Since you know that -6 is X, you're going to label it X(subscript 1) and since you know that 7 is Y, you're going to label it Y(subscript 1).
You're going to want to do the same thing with the other set of coordinates as well. -6 will be X(subscript 2) and -2 will be Y(subscript 2).
Then you need to set the labeled coordinates up in the following formula:
m=y(subscript 2) - y(subscript 1) / x(subscript 2) - x(subscript 1)
and then solve for your slope!
Answer Choice B
Step-by-step explanation:
X^2 + 2x - 15
factors into (x+5)(x-3)
set this equal to 0 and get that x=-5 and x=3
Answer:
(2x - 3a³) ,(2x + 3a³)
Step-by-step explanation:
Given that
4x^2-9a^6
As we know that
x² - y² = ( x+y)(x-y)
So
4x^2-9a^6 = (2x)² - (3a³)²
By using the above formula
x² - y² = ( x+y)(x-y)
4x^2-9a^6 = (2x)² - (3a³)²
4x^2-9a^6 = (2x - 3a³) (2x + 3a³)
So the factor is (2x - 3a³) ,(2x + 3a³)
To verify
Multiple both factors
(2x - 3a³) (2x + 3a³) = 2x .2x -2x . 3a³ + 3a³ . 2x - 3a³. 3a³
=4x² - 9 a ⁶
