B!
The equation x-4y= -4 is the graph, right? So that means when x is, lets say, 2, then:
2-4y= -4
Simplify
-4y=-6
y=3/2
Now if you think about it, if you plug in any number for x and get some value of y, that is the point on the graph at that x value.
Hope this helps!
Answer:
5/8
Step-by-step explanation:
1/4+3/8=5/8
I’m pretty sure it’s 9x+8
This is not possible, unless x = 1.
We observe that 14 is 4 more than twice 5.
The scooter's rate is 14 mph.
The bicycle's rate is 5 mph.
_____
time = distance/rate
14/(2b +4) = 5/b . . . . . . let b represent the bicycle's speed in mi/h
14b = 10b +20 . . . . . . . .cross multiply
4b = 20 . . . . . . . . . . . . . subtract 10b
b = 5 . . . . . . . . . . . . . . . divide by 4. Same answer as above.
