Answer: 4 hours

Step-by-step explanation:

Let the number of hours that the repair take be represented by h.

Since the cost of Sam's car repair is $20 an hour plus $180 for parts and the total cost was $260, this can be formed into an equation as:

180 + 20h = 260.

20h = 260 - 180.

20h = 80

h = 80 / 20

h = 4

The repair took 4 hours

Answer:x= -1, x=7

Step-by-step explanation: You will want to use the quadratic formula

X=-24)+/-[(-24)^2-4*4(-28)/2.4

Then separate the equations

x=24+32/8  And x=24-32/8

so x=7 and x= -1

Answer:

Well, 60 (minutes in an hour) divided by 12 (from the problem) is 5, so you have to multiply that 5 by the 5 from the problem to find that the train is going 25 (5*5) mph. Just double this for two hours, and you result in 50!

Answer:

x=1  7

Step-by-step explanation:

The constant of proportionality  is gotten from the graph to be 5

The complete part of the question is in the attached image which is a graph.

The graph has a positive slope, which implies a direct proportionality

hence we have that the number of trees is directly proportional to the number of days spent.

Let t represent the number of tress, d represent the number of days, and k constant of proportionality

The relationship is expressed mathematically as:

t ∝ d

t = kd

using any arbitrary point from the y axis ( t ) and tracing to the x axis ( d ). We have t = 5 and d = 1. substituting the values gives

5 = k* 1

Therefore

k = 5

The constant of proportionality is 5

Answer:

b or sec dot

Step-by-step explanation:

Answer:

1) 4

2) 5

3) -23

4) 8

5) 7

6) -64

7) -10

8) 19

9) 9

10) -56

Answer:

1) = -4

2) = 5

3) = 17

4) = 8

5) = 7

6) = -64

7) = -10

8) = 19

9) = 9

10) = -56

Step-by-step explanation:

1) (-4 + 2)^2 = -2^2 = -4

2) 25 / (9 - 4) = 25 / 5 = 5

3) 4 * 5 - 3 = 20 - 3 = 17

4) 2(2 + 2) = 2 * 4 = 8

5) (-10 + 5) / 5 + 8 = -5 / 5 + 8 = -1 + 8 = 7

6) (-3 - 1)^3 = -4^3 = -64

7) 5(5 - 7) = 5 * -2 = -10

8) 2 * 7 + 5 = 14 + 5 = 19

9) (5 * 3 + 3) / 2 = (15 + 3) / 2 = 18 / 2 = 9

10) 8(-1 - 6) = 8 * -7 = -56

Answer:  (-4,0)

Step-by-step explanation:

y = 1/2x +2  

x = -4

y = 1/2(-4) + 2    [To find the solution, we use x=-4 to solve for y, so plug in -4 for x]

y = -2 + 2

y = 0

And we use y = 0, to find the x.

0 = 1/2x + 2

-2 = 1/2x            [Subtract 2 from both side]

1/2x = -2             [Rewrite it]

    x =  -2 / (1/2)

    x = -4

So we find the solution (-4,0)
