Answer:
y = 3
General Formulas and Concepts:
- Reading a Cartesian Plane
- Reading and labeling coordinates
Step-by-step explanation:
The question is asking us what the y-value is when x = -2.
According to the graph, when x = -2, y = 3.
Therefore, y = 3.
To work through a problem like this, first find how many ordered pairs you’re given. In this case, it’s 5.
The answer will always match the amount of ordered pairs given, IF no two x-values are the same. For this scenario, each x-value is unique, so you will have an answer with exactly 5 values. This rules out A and D.
From there, just take the x-value of each ordered pair, list ‘em in order, and you get your answer.
B is the correct answer
#9
3/8 x 4/11 = 3/22
#12
9/20 x 4/5 = 9/25
V=4/3pi(r^3)
V=4/3pi(9^3)
V=3,054 inches^3
Think this is right
Answer:
x = 3/2
Step-by-step explanation:
We can use ratios to solve
6 6+x
-------- = -----------
4 5
Using cross products
6*5 = 4 * (6+x)
30 = 24 + 4x
Subtract 24 from each side
30 -24 = 24+4x-24
6 = 4x
Divide each side by 4
6/4 = 4x/4
3/2 = x
