If you're trying to see which one is correct, plug in any ordered pair and try
-5 * 4 + 22 = 2
Correct so (4, 22) is the answer.
Answer:
The perimeter is 24 units
Step-by-step explanation:
Given

Determine the perimeter
To do this, we calculate the distance AB, BC and AC.
Distance is calculated as:
So, we have:
So, the perimeter (P) is:
For each pound there is 16 ounces so
divide 112 by 16
You get 7 pounds
So if her suitcase weighs 7 pounds how many more pounds can she get up to 22 pounds
22-7= 15
So she can put 15 pounds more without going over the limit
Answer:
a) 13 m/s
b) (15 + h) m/s
c) 15 m/s
Step-by-step explanation:
if the location is
y=x²+3*x
then the average velocity from 3 to 7 is
Δy/Δx=[y(7)-y(3)]/(7-3)=[7²+3*7- (3²+3*3)]/4= 13 m/s
then the average velocity from x=6 to to x=6+h
Δy/Δx=[y(6+h)-y(6)]/(6+h-6)=[(6+h)²+3*(6+h)- (6²+3*6)]/h= (2*6*h+3*h+h²)/h=2*6+3= (15 + h) m/s
the instantaneous velocity can be found taking the limit of Δy/Δx when h→0. Then
when h→0 , limit Δy/Δx= (15 + h) m/s = 15 m/s
then v= 15 m/s
also can be found taking the derivative of y in x=6
v=dy/dx=2*x+3
for x=6
v=dy/dx=2*6+3 = 12+3=15 m/s
