Hi! Would you guys mind anderring this? A submarine is at a depth of 100 feet below sea level. Then it starts to dive at a rate
Vikentia [17]

Answer:

slope (m) = -50 or -50x

Step-by-step Explanation

I'm assuming that the x-axis is divided by 1 minute segments.

The slope is defined as "the change in y-coordinate" divided by "the change in x-coordinate"

Since the y value is decreasing (negative) 50 feet per minute, then it is safe to say that the slope is -50 (feet)/ 1 minute

Therefore... the slope is -50 or -50x depending on the answer the assignment is looking for

Which expressions are equivalent to 5 x-15? Select three options.
mojhsa [17]

Answer:

b) 5 (x-3)\\c) 4 x + 3 y-15- 3 y + x\\e) -20 - 3 x + 5 + 8 x

Step-by-step explanation:

We are given the following expression in the question:

5x-15

a)

5 (x + 15)\\=5(x) + 5(15)\\=5x + 75

which is not equivalent to the given expression.

b)

5 (x-3)\\=5(x)-3(5)\\=5x-15

which is equivalent to the given expression

c)

4 x + 3 y-15- 3 y + x\\=4x+x+3y-3y-15\\=5x-15\\=5(x-3)

which is equivalent to the given expression.

d)

-7 y-6 x- 8 y + x\\=-7y-8y-6x+x\\=-15y-5x\\=-5(x+3y)

which is not equivalent to the given expression.

e)

-20 - 3 x + 5 + 8 x\\=-3x+8x-20+5\\=5x-15

which is equivalent to the given expression.

Dexter paid $74.94 for 201/5 gallons of gas. What is the price of gas where dexter filled up his vehcile?
Kaylis [27]

To make it easier to divide, turn the fraction 201/5 into decimal form which would be 40.2.

After that you can divide 74.94/40.2 and it should give you $1.86 per gallon.
