Answer:

y=2x(.10)

Step-by-step explanation:

I think this is correct but it is 0.10 times 2 because it is 2 pencils/student and each pencil cost 10 cents. We multiply by x because we need to have 2 for each student

Write an equation in slope-intercept form (y = mx + b).

Wewaii [24]

Answer:

y = 2/7x + 7

Step-by-step explanation:

We start off by putting the original equation into slope-intercept form. Subtract 7x from both sides, then divide both sides by -2. Your new equation should be y = -7/2x - 8. It's important to know that when two lines are perpendicular, their slopes (m) are opposite reciprocals of each other. So -7/2 becomes 2/7. The first part of your final equation is y = 2/7x + b.

Next, we need to find the y intercept (b). You need to plug the x and y values from the given coordinate point (-7,5) into your final equation. You should end up with: 5 = 2/7(-7) + b. Then, solve for b.

5 = -14/7 + b

5 = -2 + b

7 = b

Finally, plug the b value into your final equation and you will have your answer.

Tariq left his house and drove to the store. He stopped and went inside. From there, he drove in the same direction until he got

choli [55]

Based on the graph (see attachment), Tariq is 4 minutes after he left his house, until he got back home.

<h3>What is distance?</h3>

Distance can be defined as the amount of ground covered (traveled) by a physical object or body over a specific period of time, regardless of its direction, starting point or ending point.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

By critically observing the graph (see attachment) which models the time that elapses over the distance covered by Tariq, we have:

Time = 10 minutes - 6 minutes

Time = 4 minutes.

In conclusion, we can infer and logically deduce that Tariq is 4 minutes after he left his house, until he got back home.
