Step-by-step explanation:
I think these is your correct answer .
5(8)-2y=30
40-2y=30
2y=10
y=5
Answer:
w=-7
Step-by-step explanation:
Soooo-
W(x)=-3x-4
divide both sides by x
W=-3-4
combine like terms
W=-7
Answer:
Car A's speed is 75 miles per hour
Step-by-step explanation:
As the distance-time graph represents the straight line. Thus, the slope of any line would remain constant along the line.
We also know that in a distance-time graph, the slope of the line would be equal to the speed of the object.
Taking two points from the graph
Determining the slope
Slope = [y₂-y₁] / [x₂-x₁]
= [100 - 25] / [1 - 0]
= 75 / 1
= 75 miles per hour
Therefore, Car A's speed is 75 miles per hour
I agree 3/5! I'm pretty sure, I haven't done this in forever so
