Answer:
21 - n = 7 ; n = 14
Step-by-step explanation:
21 - 14 = 7
7 + 14 = 21
14 is 7 multiplied by 2 and 21 is 7 multiplied my 3
can be simplified to by adding the 7 and 10 to get
.
cannot be simplified any more by combining like terms.
By distributing the 2b into the parentheses, you can simplify the expression:
Here you can just add:
Thus, the only expression that cannot simplify any more using adding like terms is the second,
.
Answer:
You have to make the fraction into a whole number.

Answer:
1. Option D is correct.
2. Option B is correct.
3. Option B is correct.
Step-by-step explanation:
Inverse function defined as the the function that undergoes the action of the other function.
A function is the inverse of f if whenever y =f(x) and
To find the inverse of the function:
Q1.
Given the function: f(x) = 7x -1
Put y for f(x) and solve for x;
y= 7x -1
Add 1 both sides we get;
y + 1 = 7x
Divide both sides by 7 we get;
Put for x;
Interchange y =x, we have
Q 2.
Given the function:
Put y for f(x) and solve for x;
Add 7 both sides we get;
taking cube root both sides we get
Put for x;
Interchange y =x, we have
Q3 .
Given the function:
Put y for f(x) and solve for x;
Add 3 both sides we get;
Divide both sides by 5 we get;
taking cube root both sides we get
Put for x;
Interchange y =x, we have
Answer:
10x² - 12
Step-by-step explanation:
4x² - 7 + 6x² - 5 (combine like terms)
10x² - 12
