Answer:
2
Step-by-step explanation:
The equation is mx+b=y
The equation is not simplified yet.
2y-4x=1
Add 4x to both sides
2y=1+4x
Divide by 2
1/2+2x
For this just identify. M=slope. The number next to the x is 2. So the answer is 2
C. 6.2g can be combined with -3/8y. This is because they both end in ‘y’.
Answer:
A.
Step-by-step explanation:
idk how to explain it. all you need to do is look at the graph..... every point is (x,y). x is where it is horizontally and y is vertically
The picture below shows the formula for calculating slope
In this example:
y2 = 4
y1 = -4
x2 = 5
x1 = 3
(These are the numbers you substitute into the formula)
Calculations:
4 - (-4) = 8
5 - 3 = 2
8/2 = 4
As you can see, after the values are substituted into the equation & simplified, the slope is equal to 4
Answer: 54.4 mph
Step-by-step explanation:
First find the distance to the train station. If it took Carlos 4 hours to come back driving at 68 mph, the distance is:
= Speed * time
= 68 * 4
= 272 miles
This means that Carlos drove for 5 hours to cover 272 miles the first time. His average speed was therefore:
= Distance / time
= 272/5
= 54.4 mph
