Answer:

8 and 9

Step-by-step explanation:

1. subtract 3r from both sides to get -1r≤-8

2. divide both sides by -1 to get r by itself r=8

3. any number greater than 8 will be a true statement

How many units long is a segment whose endpoints are (2,3) and (7,15)?

Ahat [919]

Answer:

13 units

Step-by-step explanation:

Distance formula: $d = \sqrt{(x2-x1)^2 + (y2-y1)^2}$

Simply plug in your variables

$d = \sqrt{(7-2)^2 + (15-3)^2}$

$d = \sqrt{5^2 + 12^2}$

$d = \sqrt{25 + 144}$

$d = \sqrt{169}$

d = 13

Answer:

Step-by-step explanation:

54 has 4 ones

and 5 tens

37 has 7 ones

and 3 tens

subtracting ones

7 ones are taken from 54

so along with the existing 4, 1 ten is decreased and another 3 ones are decreased resulting in 7 ones now

now 54 has 5-1= 4 tens

subtracting tens we get 4-3=1

Therefore 1 ten and 7 ones

⇒ 17

Let f(x)=−1/4(x+4)^2−8 . What is the average rate of change for the quadratic function from x=−2 to x = 2? Enter your answer in

kiruha [24]

Answer:

Average rate of change of function is -2.

Step-by-step explanation:

Given $f(x)=\frac{-1}{4}(x+4)^2-8$ .

we have to find the average rate of change for the quadratic function from x=−2 to x = 2.

$f(-2)=\frac{-1}{4}(-2+4)^2-8=\frac{-1}{4}(4)-8=-9$

$f(2)=\frac{-1}{4}(2+4)^2-8=\frac{-1}{4}(36)-8=-17$

The average rate of change of the function f(x) on interval [-2,2] is

$\frac{f(b)-f(a)}{b-a}=\frac{f(2)-f(-2)}{2-(-2)}=\frac{-17-(-9)}{4}=\frac{-8}{4}=-2$
