Answer:
x = 0, 6, -1
Step-by-step explanation:
We need to set f(x) = 0 to find the values of x for this expression.
So
We will factor out an x and do middle term factorization to arrive at our answer for x (there will be 3 x values):
These are the 3 values for x.
Answer:
Option (3)
Step-by-step explanation:
Since, every student is responsible for the caring of 4 animals during every hour,
Number of animals cared for ∝ Number of hours spent at shelter
a ∝ h
a = kh
Here 'k' = proportionality constant
For h = 1 and a = 4,
k = 
k = 4
a = 4h
By this equation,
For h = 2,
a = 8
For h = 3,
a = 12
For h = 4,
a = 16,
For h = 5,
a = 20
Since, for every input value there is a different output value,
Diagram shows a function.
Therefore, Option (3) will be the correct option.
Answer:
20 + 10 = 30
Step-by-step explanation:
The sum of x and y is 30. In other words, x plus y equals 30 and can be written as equation A:
x + y = 30
The difference between x and y is 10. In other words, x minus y equals 10 and can be written as equation B:
x - y = 10
Now solve equation B for x to get the revised equation B:
x - y = 10
x = 10 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 30
10 + y + y = 30
10 + 2y = 30
2y = 20
y = 10
Now we know y is 10. Which means that we can substitute y for 10 in equation A and solve for x:
x + y = 30
x + 10 = 30
X = 20
Summary: The sum of two numbers is 30 and their difference is 10. What are the two numbers? Answer: 20 and 10 as proven here:
Sum: 20 + 10 = 30
Difference: 20 - 10 = 10
