Answer:
C
Step-by-step explanation:
What we have to do here is to select a point from the graph
We can select the point (-8,1)
What this simply mean is that when x = -8, y = 1
Now, let us take a look at the second third option
f(-8) will be the cube root of -(-8) , with 1 subtracted from it
The cube root of 8 is simply 2, subtracting 1 from it will yield 1
so that makes the point (-8,1) valid
Answer:
A or D is the answers for the question
Step-by-step explanation:
please give me brainlest and follow me
Given function:
To find:
The input if the output is 32.
The output if the input is 4.
Solution:
Input is x and output is c.
Substitute c = 32 in f(x).
Divide by 4 on both sides, we get
Taking cube root on both sides.
The input is 2 if the output is 32.
Substitute x = 4 in f(x).
The output is 256 if the input is 4.
Answer:
Below in bold.
Step-by-step explanation:
Standard form is Ax + By = C
where A, B and C are integers and A must be positive.
So the first 2 are already in standard form but the last 2 can be converted to standard form by multiplying each term by -1:
-12x+3y=27
= -1*-12x + -1*3y = -1*27
12x - 3y = -27 is the answer.
The last one is:
24x + 12y = -60.
Answer:
x=10 y=2
Step-by-step explanation:
4x-2y=36 x2
5x-4y=42
8x-4y=72
5x-4y=42
3x-0=30
30÷3=10
x=10
(4x10)-2y=36
40-36=4
4÷2=2
y=2
