Answer:
C
Step-by-step explanation:
First, Karen only has $20, so her spending cannot go over this amount. That would would that she can spend exactly $20 or less than $20. We need a equal to/less than sign before $20, so answer choices A and D can easily be eliminated.
Next, the admission costs $6. This is a cost that Karen will only pay one time, so it's represented by + 6. This eliminates B, but I will still explain why C is completely correct.
Each ride costs $2, meaning that we can represent this amount with 2x, which is just $2 times the amount of rides she will go on. When fully written out, the inequality is 2x + 6 (less than or equal to sign) 20, making C the correct answer.
Answer:
847.8 sq meters
Step-by-step explanation:
Formula:
A= 2πrh + 2πr^2
A= 2(3.14)(9)(6) + 2(3.14)9^2
A= 339.12 + 508.68
A= 847.8
= 4x - 11
x is the input, y is the output.
So if you want to know what input is needed to get an output of 10, set y to 10 and solve for x:
10 = 4x - 11
21 = 4x
x = 21/4
Answer:
9:6
Step-by-step explanation:
You can find x by setting the ratios equal to each other.
Now you just need to solve for x.
The ratio is 9:6.
Answer:
(4,-1), (3,-1),(2,-1) or (1,-1)
if you draw a horizontal line through the point (5,-1) you will notice it crosses through every point ending with -1
