Answer: Falling
Step-by-step explanation:
Once you rearrange this equation into y-intercept form and you get y = -4x-3, you then graph the line and the line appears to be decreasing down.
Answer:
C
Step-by-step explanation:
Domain of the function is the whole R
If your "original" number is 27, this is the work:
percent change = change/original * 100
percent change = (36-27)/27 * 100
percent change = 9/27 * 100
percent change = 1/3 * 100
percent change = 33 1/3
You need to solve for x or y in one equation and and substitute it into the other equation in place of the variable that corresponds to it.
I don't know what you mean by equation 1. I assume you mean x + y = 7 is equation 1.
If so, solve for y as step 1.
x + y = 7
y = - x + 7
The y-intercept is 7.
Your directions do not say to solve the system of equations.
If you need to solve by graphing, use DESMOS or your graphing calculator. The solution of the system of equations is the point on the graph where the two equations meet or touch each other.
