-3=z-8
Move the variable to the left side and change it’s sign

-z-3=-8
Move the constant to the right side and change its sign

-z=-8+3

Now you calculate the sum

-z=-5

Change both signs of the equation

z=5, therefore z=5 your answer.

Johnny went to an apple farm to pick some apples. The admission to get in was $5.00 and the apples cost $0.75 per pound.
sasho [114]

Answer:

y=0.75x+5

Step-by-step explanation:

It would be this equation because you start at 5, which is the y-intercept, then you add 0.75 for every pound of apples. So on a graph you would start at 5 on the y-line then go up by 0.75

What is the slope of the line perpendicular to the segment with endpoints (2,0) and (-6,3)?
r-ruslan [8.4K]

Answer:

A line that passes (2, 0) and (-6, 3) has slope:

S1 = (-6 -2)/(3 - 0) = -4/3

Another line that is perpendicular with above line has slope:

S2 = -1/S1 = -1/(-4/3) = 3/4

=> Option B is correct

Hope this helps

A basketball player makes 80% of her free throws. The random numbers below represent 20 trials for
Taya2010 [7]

Answer:

0.6

Step-by-step explanation:

  • The numbers 0 to 7 represent a made free throw
  • The numbers 8 to 9 represent a missed  free throw.

Given the simulation data

(8,2) (9,3) (4,0) (5,8) (2,7) (2,0) (5,4) (8,0) (0,4) (9.1)

(9,6) (6,5) (4,4) (1,7) (0,4) (8,5) (8,8) (1,7) (3,5) (0,3)

  • A pair that contains only numbers between 0 and 7 shows the player makes both throws.

These pairs are:

(4,0)  (2,7) (2,0) (5,4)  (0,4) (6,5) (4,4) (1,7) (0,4) (1,7) (3,5) (0,3)

There are a total of 12 cases where the player makes both throws.

Therefore:

P(Player makes both throws)=12/20=0.6
