A drill is used to dig down into the earth. After 2 hours, the drill is 12 meters below the surface. After 5 hours, the drill is 30 meters below the surface. Which equation represents the depth of the drill in meters, y, after ​x hours of drilling?

Answers

Answer 1

Answer:

6y = x

Step-by-step explanation:

All that equation is saying is that for every 1 hour drilled (x), 6 meters (y) are drilled.

y = distance in meters

x = time

12y = 2x

12y/2 = 2x/2

6y = x

30y = 5x

30y/5 = 5x/5

6y = x

Answer 2

The equation representing the depth of the drill in meters, y, after ​x hours of drilling is y = -6x

Since the slope is 3, hence it passes through the point (-4.67, 0). Hence the equation of the line is y = 3x + 14.

A linear equation is in the form:

y = mx + b;

where m is the slope, b is the y intercept and y, x are variables.

Let y represent the depth of drill in meters after x hours of drilling. Hence:

Since after 2 hours, the drill is 12 meters below the surface, it can be represented by (2, 12). Also after 5 hours, the drill is 30 meters below the surface, it can be represented by (5, 30)

The equation of the line is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1) \\\\y-(-12)=\frac{-30-(-2)}{5-2}(x-2) \\\\y+12=-6(x-2)\\\\y+12=-6x+12\\\\y=-6x[/tex]

The equation representing the depth of the drill in meters, y, after ​x hours of drilling is y = -6x

Mary has been saving her weekly allowance for the past 20 weeks. She started with $100 and now has $300. Which equation can be used to find the amount of money Mary receives for her weekly allowance?

Answers

Answer:

Step-by-step explanation:

You should set this up as an y = mx + b equation. Since 300 is her final number, that will be your y value. She started with 100, so that will be your b value. 20 is the number related to the variable you don't know so that will be your m.

300 = 20x + 100

-100            -100

200 = 20x

divide both sides by 20

APE X

for m(x)=-2x+7, find the value of x for which m(x)=13

Answers

Answer:

x = -3

Step-by-step explanation:

m(x) = -2x + 7

13  = -2x + 7

6 = -2x

x = -3

The answer is x= -3




The explanation if you need it is since m(x)=13 we get the equation 13=-2x+7. Then we use the equation to find x.


13= -2x+7
-7 -7
6= -2x
— —
-2 -2

-3=x

You then want to check your answer by substituting -3 for x

13= -2(-3) +7
13= 6+7
13=13
If your answers match then your answer is correct

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each, and the laptops cost $439.00 each. If the math department has $6,500 to spend and purchases 30 textbooks, how many laptops can they buy

Answers

Answer:

6 laptops

Step-by-step explanation:

First, find the amount spent on the textbooks:

30(116)

= 3480

Subtract this from the total amount they have to spend:

6500 - 3480

= 3020

Divide this amount by 439 to find how many laptops they can buy:

3020/439

= 6.8

Round down to 6 since you can only have full laptops:

= 6

So, they can buy 6 laptops
