Answer:
It's B
Step-by-step explanation:
The original equation is y - (y intercept)= slope(x-(x intercept))
Answer:
Hey there!
The range is the possible y-values of any function. That's the definition, but identifying range takes practice, so let me know if you need any help with that.
Hope this helps :)
Answer:
C, D, E, F
Step-by-step explanation:
Remember y=mxb?
m is slope and b is y-intercept
so y=2/7x-9
Remember that slope is RISE/RUN so for every 2 squares that you go up, you go 7 squares to the right.
Also remember that since your graph is going thru your Cartiesian Plane in quadrent 4, your y value in your ordered pairs will most probably be a negative.

Answer:
Step-by-step explanation:
3x + 3x + 5 + 5 = 6x + 10
4hour.
<h3>Justification:</h3>
<u>We are given time takes to travel is inversely with an average speed</u>.
- When average speed is 40mph, it takes 2hour.
Then,
<u>If average speed is 80mph, let time taken be x</u>:
- 40/2 = 80/x
- 40x = 160
- x = 160/40
- x = 4
<u>Hence, it takes 4 hour to travel to a destination with 80mph</u>.
