Answer:
70 hours.
Step-by-step explanation:
you need to subtract 450 from 75 which tells you you need 350 more dollars then you need to do 5x70 which gives you 350.
Input (x-value)
Output (y-value)
You need to find the x-value that produces a y-value of -1. Since you know:
y = -1 Use the rule, and substitute/plug this into the equation
y = -2x + 33 Plug in -1 for "y" in the equation since y = -1
-1 = -2x + 33 Subtract 33 on both sides
-1 - 33 = -2x + 33 - 33
-34 = -2x Divide -2 on both sides to get "x" by itself
![\frac{-34}{-2}=\frac{-2x}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-34%7D%7B-2%7D%3D%5Cfrac%7B-2x%7D%7B-2%7D)
17 = x
An input of 17 yields an output of -1
Answer:
Step-by-step explanation:
IIada, Distance = speed*time, so speed = distance/time right?
The plane went the same distance each direction.
s - w = 40/30 = 4/3
s + w = 40/20 = 2
Adding the two equations together...
s = 5/3
w = 1/3
So the speed of the wind in miles per hour is 1/3
3x + 2y = 8
