ANSWER:
We know that,
Speed = Distance/Time
So, Time taken = 20kmh-¹/160km
There is no. Question it’s telling you the answer
You take the amount of days and multiply by 50! so if the days are d, and cost is c then c=50d
hope this helps, can i have brainliest!
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:
(-3 -5)/(9+5)= -8/14= -4/7
y - 5 = -4/7(x + 5)
y - 35/7 = -4/7x - 20/7
y = -4/7x + 15/7
