A fish is swimming at a constant rate toward the ocean floor. The equation
y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.
Which statement best describes the depth of the fish, given this equation?

A.From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.

B.From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.

C.From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

D.From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.

Answers

Answer 1

Answer:

C.

explanation: if the fish is swimming towards the ocean floor it's descending 7 meter per second because -7x is the constant and 3 is the y-intercept or where the fish started

Mr. Jackson has a total of 12 employees. He wants to buy each employee 3 aprons that will cost $7.79 each, 1 cap that will cost $5.68, and a t-shirt that costs $13.99. How much will Mr. Jackson need to spend to purchase the items for his employees?

Answers

12/3 is 4 so multiply each by 4 so 7.79 x 4 is 31.16 5.68x4 22.72 13.99x4 55.96


31.16 + 22.72+ 55.96

Answer: $109.84

Answer: $516.48

Step-by-step explanation: Multiply 7.79 by 3 because it's 3 for each employee then multiply by 12 for each employee which equals 280.44. then 5.68 x 12 which is 68.16 for the cap. then 13.99 x 12 for the shirt which is 167.88. add 280.44, 68.16, and 167.88 to get 516.48.

I hope it helps, I did the math!

Hello again davetriona12! I can help you.

We have 2.99, 3.19, 3.39, and 3.79

In order to solve this, we need to find out how much is being added every time. To do this, we will subtract 2.99 from 3.19 which gives us 0.20

So each time, 0.20 gets added.

Now that we have that information, we are ready to find the blanks.

For the first blank, we will subtract 2.99 - 0.20 which will give you 2.79

For the second blank, we will add 0.20 to 3.39 which will give you 3.59

Hope this helps you!

Which statement describes the relationships between x and y in these two equations?

y = 3x

y = x + 3




In y = 3x, the value of y is 3 times the value of x, and in y = x + 3, the value of y is 3 more than the value of x.

In y = 3x, the value of y is 3 more than the value of x, and in y = x + 3, the value of y is 3 times the value of x.

In y = 3x and y = x + 3, the value of y is 3 more than the value of x.

In y = 3x and y = x + 3, the value of y is 3 times more than the value of x.

A submarine starts at 0 units and has groups of 3 floats and groups of 4 anchors attached.
Using these groups of floats and anchors, write as many different expressions as you can that would make the submarine's final position -5 units.
write three expressions

Answers

Answer:

-12

Step-by-step explanation:

The three equivalent expressions of the final position are:

-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

From the question,

Each float takes a step of 5 unitsEach group takes a step of 2 units

So, the final position of the submarine is:

Final = -(5)(3) - (2)(4)

The minus "-" sign implies that the submarine moves downwards i.e. it sinks

The equivalent expressions of the final position are:

-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

Step-by-step explanation:

Answer:


Meaning: Each floor of the buiding has a height of 15 feet.
Step-by-step explanation:
The missing figure is attached.
By definition, the ratios are used to compare two or more things or quantities.
In this case you must write the ratio of height of the building to the number of floors it has.
You can observe in the figure that the building has a height of 135 feet, and, since it has 9 floors, you can write the following ratio:

Therefore, dividing the numerator by the denominator, you get that the unit rate is:

This means that each floor of the buiding has a height of 15 feet

How much should he leave for the tip?

A. $2.18

B. $2.61

D. $261.00

Answers

It’s B because you divide 18 percent from 14.50 dollars.
It would be B. Because 14.50 times .18 equals 2.61. Just put a decimal on it and move it to the right twice and multiply that by 14.50. If you need a better explanation you can message me! Hope this helps!:)
