Answer:
5
Step-by-step explanation:
The difference of x-values is the horizontal change:
0 -(-5) = 5
The answer would be 3x - 5
Hope this helps!!!
Let A represent the speed of car A. Using your formula,
.. A*2 = D
.. (A +15)*1.5 = D . . . . . the same distance in a shorter time at a higher speed
Equating the two expressions for D, we get
.. 2A = 1.5(A +15)
.. 2A = 1.5A +22.5 . . . . . eliminate parentheses
.. 0.5A = 22.5 . . . . . . . . .subtract 1.5A
.. A = 22.5/0.5 = 45 . . . .divide by 0.5
Car B was 15 mph faster than this.
Car B traveled at 60 miles per hour.
2/15
2 * 1 is 2
3 * 5 is 15
Answer:
Step-by-step explanation:
We are given the function f(x) = -3/4(x) +6.
We know that the slope intercept form of a line is y = mx + b
Here, the slope m = -3/4.
The y-coordinate of the y intercept is b = 6 so the y-intercept is at the point (0,6) [x is always 0 at the y-intercept]
If you have to points you can graph the line, we only have the point (0,6).
To find the second point we use the slope.
We add the bottom point of the slope to the x coordinate of the y-intercept and we add the top part of the slope to the y coordinate of the y-intercept, so our second point is (0 + 4, 6 +(-3)) = (4, 3).
You then plot the points we have: (0,6) and (4,3) and draw the line through them.
