Answer: -3

Step-by-step explanation:

The average rate of change is \frac{f(b)-f(a)}{b-a}. All we have to do is to plug in our values.

a=-2

b=-1

f(b)=f(-1)=(-1)²+10=11

f(a)=f(-2)=(-2)²+10=14

With our values listed, all he have to do is to plug them in.

\frac{11-14}{-1-(-2)} =\frac{-3}{1}=-3

Using the pythagorean theroem to solve this problem (a squared plus b squared equals c squared)
C would be the hypotenuse, which in this case is the five ft ladder.
The other known length of the leg is 4 ft.
5^2-4^2=25-16=9
9 must equal a^2 and a must equal 3
The correct answer is 3 ft

Which expression represents the calculation “subtract 4 from 12, then divided by 8”? A) 4 ÷ (12 − 8) B) (12 − 4) ÷ 8 C) (4 − 12)
Svetlanka [38]

The answer is B

As the question states that you need to "subtract 4 from 12" that means that you are taking 4 away from 12, so it would be 12-4.

Then it says to divide by 8. This means that for the subtraction to happen first, it must be withing parenthesis, so that would make the expression become

(12-4)÷8

Answer:

y=x+3

(0,3)(1,4)

y=x+2

(0,2)(1,3)

Step-by-step explanation:

- For Y=X+3 it could be any point for Y as long as X is 3 less than Y.

- For Y=X+3 it could be any point for X and long as Y is 3 more than X.

- For Y=X+2 it could be any point for Y as long as X is 2 less than Y.

- For Y=X+2 it could be any point for X and long as Y is 2 more than X.
