Answer:
5. C
6. A
Step-by-step explanation:
To find the answer, plug in the x- and y-values into each equation. When the equation comes to be true that is your answer.
So for question 5, you plug -5 into the x and 13 into the y for each equation. The first equation will give you an answer of 13 = -7, which isn't true.
The second will give you 13 = 7, so you keep going.
The third gives you 13 = 13, which is true, so that one must be the answer.
Do this for every question and it will give you the answer.
Answer:
Graph of a one-to-one function if f is a one-to-one function then no two points (x1,y1), (x2,y2) have the Same y-value. Therefore horizontal line cuts the graph of the equation y = f (x) more than omce. Horizontal line test: A graph passes the horizontal line test if each horizontal line cuts the graph at almost once.
Answer:
Step-by-step explanation: This is for #6 Volume = pi·r2·h
Volume = pi·(5x+2)2(2x+8)
Answer:
It's 1/2*DB*AC
Step-by-step explanation:
You would add the like terms by changing them over the equals sign
6r+18=-26+6r
subtract 6r from both sides
18=-26
which is false
