Answer:

y = -2x + 4  

Step-by-step explanation:

We are given that a line has a slope (m) of -2 and passes through (5, -6).

We want to write the equation of the line.

There are three ways to write the equation of the line:

Any of these forms will work, however let's put it into slope-intercept form as that is the most common way.

As we are already given the slope, we can immediately plug that into the equation.

Substitute m with -2.

y = -2x + b

Now, we need to solve for b.

As the equation passes through (5, -6), we can use its values to help solve for b.

Substitute 5 as x and -6 as y.

-6 = -2(5) + b

Multiply.

-6 = -10 + b

Add 10 to both sides.

4 = b

Substitute 4 as b.

y = -2x + 4  

Answer:

Step-by-step explanation:

–0.4x – 10 > 14

           –0.4x > 24

                    x < –60

the correct solution to the inequality – 0.4x – 10 > 14 is x < – 60.

Inequality refers to a mathematical relationship between two values that are not equal.

The correct work that uses properties of inequality to find the solution to – 0.4 x – 10 > 14 is:

– 0.4 x – 10 > 14

Subtract 10 from both sides:

– 0.4 x > 24

Divide both sides by – 0.4 (note the change in inequality direction when dividing by a negative number):

x < – 60

Therefore, the correct solution to the inequality – 0.4x – 10 > 14 is x < – 60.

Answer:

5x − k = 100

[tex]x=\frac{100-k}{5} \\[/tex]

Step-by-step explanation:

The amount she spends on lunch is x = (100 + k) /5.

Given: Janet spent $100 on books.

This was k dollars less than five times what she spent on lunch.

We can construct an equation from it :

5x-k = 100

Thus , x = (100 + k) /5.

In the die the total no. of students are 25

We know that,

∴ P(E) = Number of favourable outcome / Number of all possible outcome

Here we have to find the probability of the event of finding the no. of males.

⇛ P(E) = 14 / 25 (Answer)

And we are done !!

Probability helps us to know the chances of an event occurring. The probability that no males are selected is 0.3033.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that A math class consists of 25 students, 14 female and 11 male. Two students are selected at random to participate in a probability experiment.

Now, since we need to compute the probability that no males are selected, which can also be taken as the probability of both the students selected are girls. Therefore, the probability can be written as,

Probability = (14/25) × (13/24)

                  = 182/600

                  = 0.3033

Hence, the probability that no males are selected is 0.3033.

Answer:

If she traveled 2 miles in 8 minutes, the constant of proportionality is y=1/4x. So for every minute she rode her bike, multiply that by 1/4.

Step-by-step explanation:

Answer:

1.5 hours

Step-by-step explanation:

Number of miles = 25 miles

Average speed = 7.4 miles per hour

Break after 13.9 miles

How many more hours does he run

Speed = distance / time

Total time for 25 miles :

Time = distance / speed

Time = 25 / 7.4

Time = 3.378 hours

Total time to cover 13.9 miles :

Time = 13.9 / 7.4

Time = 3.378 hours

Time = 1.878 hours

Difference = (3.378 - 1.878) hours = 1.5 hours

Hence, he to ran for 1.5 hours after taking a break

The total time required for the 25 miles run is 3.378 hours and he will run for 1.5 hours after the break.

Given information:

Roberto runs 25 miles.

The average speed is 7.4 miles per hour.

He takes a break after 13.9 miles.

Now, speed is defined as the ratio of distance and time.

So, the time taken by him to run first 13.9 miles will be,

[tex]s=\dfrac{d}{t}\\7.4=\dfrac{13.9}{t_1}\\t_1=1.878[/tex]

So, he ran for 1.878 hours to cover 13.9 miles.

Now, the total time of the 25 miles run will be,

[tex]T=\dfrac{25}{7.4}\\T=3.378[/tex]

So, the total time of the run is 3.378 hours.

After the break, he will run for 3.378-1.878 hours = 1.5 hours.

Therefore, the total time required for the 25 miles run is 3.378 hours and he will run for 1.5 hours after the break.

Answer:

40 minutes

Step-by-step explanation:

It takes 30 mins to shape 10 pots, and heating all 10 pots takes 10 mins. Add 30 and 10 minutes to get: 40 minutes.

Answer:

3p + 10; 40 minutes

Step-by-step explanation:

It takes 3 minutes to shape one pot.

It takes 3p minutes to shape p pots.

A batch of pots has p pots and takes 10 minutes in the kiln.

The total time it takes to make 1 batch is the time to shape the pots, 3p, plus the time in the kiln, 10 minutes.

The expression is

3p + 10

For a batch of 10 pots, p = 10.

3p + 10 = 3(10) + 10 = 30 + 10 = 40

Answer: 3p + 10; 40 minutes

Answer:

C. The amount of gas left in Steve's car at his next visit to the gas

station is a function of the distance he drove.

Step-by-step explanation:

From the question, the car starts with a full tank of gas and the more the distance covered, the less gas will be left in the car at the next visit to the gas station.

The variables to take note are the distance travelled and the amount of gas left in the car at next visit to the gas station.

This means the farther he drives, the less gas will be left in the car because longer distances travelled consumes more gas in the car thus less gas will be left when the next visit to the gas station occurs.
