Answer:
the rate of change is 0
Step-by-step explanation:
rate of change or slope = (y2-y1)/(x2-x1)
= (-11--11)/(-38--40)
= (-11+11)/((-38+40)
=(0/2)
=0
this makes sense because the y value does not change
you must multiply with the following equation to obtein the numbers of stamp
( 2*20)+(4*10)= 40+40= 80 , it means that Carmen has 80 stamp
An inequality can be formed by simply translating the problem statement to numerical expressions.
From the problem we know that

added with

hours should be equal or greater than

(helpful insight from the keyword "at least"). Therefore, it's inequality would look like:

(>= is used instead of ≥ for constraints in formatting)
The inequality above best models the situation.
Answer:
2(7) + 5 = 19
Step-by-step explanation:
Okay, so do it like this:
2x+5
x = 7
2(7) + 5
2(7) = 2 x 7
2 x 7 = 14
Now it's 14 + 5
14 + 5 = 19
Your answer is 2(7) + 5 = 19
Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°
