B i think that because there’s no quantity
Answer:
He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.
Step-by-step explanation:
After n consecutive serves, his total number of serves is going to be n+8, since he has already served 8 times. In the best case, his number of successful first serves is n+2.
His percentage of succesful first serves is the division of the number of succesful first serves divided by the total number of serves. So

We want
. So







He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.
No, it does not equal 0. Lets multiply it out and see what it actually equals.
15/25 * 25/15
15*25 / 25*15
375 / 375
Anything over itself is 1, so the final answer for the multiplication is 1.
Y + 2x = 3....put this in y = mx + b form by subtracting 2x from both sides
y = -2x + 3
so u have a slope of -2 and a y int of 3 or (0,3)
ur x int can be found by subbing in 0 for y and solving for x
y + 2x = 3
0 + 2x = 3
2x = 3
x = 3/2 or 1.5....so ur x int is (1.5,0)
so go ahead and plot ur intercepts (1.5,0) and (0,3).....and since u have a slope of -2, start at (0,3)....come down 2 spaces, then go right 1 space....plot that...then down 2 and to the right 1...plot that...keep doing this and u should cross the x axis at (1.5,0)....then connect ur plotted points and u have ur line.
Answer:
0.05
Step-by-step explanation:
Slope is the vertical drop or rise to the horizontal distance;
Slope =
Let us convert 4 miles to feet;
1 mile = 5280ft
4 miles = 4 x 5280 = 21120ft
Slope =
= 0.05
The slope is 0.05
