The mechanic does 4 oil changes in 2 hours. How many oil changes can the mechanic do in 8 hours?

Answer:

[tex]\huge\boxed{\sf 4x + 6}[/tex]

Step-by-step explanation:

Adding x - 2 and 3x + 8

= x - 2 + 3x + 8

Combine like terms

= x + 3x - 2 + 8

= 4x + 6

Answer:

d) A ball is thrown directly upward from an initial height of 7 feet, will reach a maximum height of 19.3 ft in 0.9 s, and finally will hit the ground in 2 s.

Step-by-step explanation:

The y-intercept of the curve is at (0, 7) so when t = 0, the ball is 7 ft above the ground.  Therefore, the ball is thrown from an initial height of 7 feet.

The maximum point of the curve is (0.9, 19.3) which means the maximum height is 19.3 feet is reached after 0.9 seconds.

Finally, the curve intercepts the x-axis at t = 2, which means at 2 s the ball's height is zero, i.e. it hits the ground at 2 s.

[tex]\displaystyle y = 9[/tex]

Explanation:

Both ordered pairs have similar y-coordinates. In addition, any straight line like this one, is considered a zero rate of change [zero slope], therefore you have your equation above.

Answer:

hope this help uhh.. Have a good day.

Step-by-step explanation:

the equation is

3x + 5y = 18

the blue dot is the interception of the line with the y-axis. that is the y value, when x = 0.

the equation for x = 0 is

3×0 + 5y = 18

5y = 18

y = 18/5 = 3 3/5 = 3.6

the red dot is the interception of the line with the x-axis. that is the x value, when y = 0.

the equation for y = 0 is

3x + 5×0 = 18

3x = 18

x = 18/3 = 6

so, you need to move the blue dot to 3.6 and the red dot to 6.

Answer:

5/8 < 7/12

Step-by-step explanation:

To find which is greater we can turn them into a decimal..

5/8 ⇒ 0.625

7/12 ⇒ 0.583

Then, we compare the two decimal numbers to get the answer.

0.625 is greater than 0.583.

Therefore, 5/8 is greater than 7/12 .

CloudBreeze]

Answer:

5/8 > 7/12

Step-by-step explanation:

I gave the two fractions a common denominator so it could be judged easily.

As you can see here, 5/8 is slighty higher than 7/12

5/8*3/3= 15/24

7/12*2/2=14/24

Answer:

Step-by-step explanation:

3) Final step of problem 1: -5x + 6

-5x + 6 = -5*(-2) + 6

           = 10 + 6 = 16

4) x + -4 + -2(3x -5 ) = 8 + -4 + -2(3*8 -5)

                                = 4+ -2(24 -5)

                                = 4 + -2*19

                                 = 4 - 38

                                  = -34

We can write the two given inequalities as:

0 < x < 1/3

And the graph of it can be seen below.

Here we want to graph the inequalities:

x < 1/3

x > 0.

To do it, we can rewrite the inequality as:

0 < x < 1/3.

To graph this, we need to work with a number line. First, we will mark both of the ends of the inequality, that is x = 0 and x = 1/3, both will be graphed with open circles, which means that these points are not solutions. Then, we need to shade the region between these points.

The graph can be seen below.

Step-by-step explanation:

Answer:

what is the length we are talking about i need a little more info

Step-by-step explanation:

Answer:

1.085 metres

Step-by-step explanation:

1 cm = 0.01 m

8.5 cm = 0.085 m

1m+0.085m=1.085 metres

Answer:

1.085 metres

Step-by-step explanation:

100 centimetres = 1m

what about 8.5 cm?

Divide the centimetres by 100

8.5/100 = 0.085m

Then add the metre(s) you already have which is 1

thus 0.085 + 1

1.085m
