WILL MARK THE BRAINLIST!!
In the previous activity, you found an equation with a negative unit rate, y = -50x – 100. This equation gave the depth of a submarine, y, given time, x. It assumes that the submarine starts at a depth of 100 feet, and then starts descending at a rate of 50 feet per minute. In this activity, you will graph the equation.
Part A
Graph the equation y = -50x – 100 by going to your math tools and opening the Graph tool. Set the scale of the y-axis to range from -150 to 50, and set the x-values to range from -5 to 10. Paste a screenshot of your graph in the answer field.

Answer:

[tex]3781/9000[/tex]

Step-by-step explanation:

[tex]0.42\overline{1}=42/100+0.00\overline{1}[/tex].

Recall that [tex]0.\overline{1}=1/9[/tex].

So, we want [tex]42/100+1/9*1/1000[/tex].

This simplifies to [tex]21/50+1/9000[/tex].

We know that [tex]21/50=(21*180)/(50*180)=3780/9000[/tex].

So, our expression is [tex]3780/9000+1/9000=3781/9000[/tex], which can't be simplified more.

So, our answer is [tex]\boxed{3781/9000}[/tex] and we're done!

Answer:

252 m

Step-by-step explanation:

Triangles: (base x height) 2

Rectangles: width x length

Triangles = 2(7*6)/2 = 42 m

Rectangles = 3(7*10) = 210

210 + 42 = 253 m

Answer:

51.68 miles per hr

Step-by-step explanation:

To find the average rate, divide the total miles traveled by the total amount of time.

325 miles / 6 1/4 hours = 51.68 miles per hr

Answer:

The correct answer is 24

Step-by-step explanation:

To solve this math problem, you will need to divide 20.40 with 1 (1 is 100% as a decimal) and 0.15 (0.15 is 15% as a decimal).

--

[tex]20.40[/tex] ÷ [tex](1-0.15)[/tex]

--

First, subtract 1 and 0.15

[tex]1-0.15=0.85[/tex]

Next, divide 20.40 and 0.85

[tex]20.40[/tex] ÷ [tex]0.85 = 24[/tex]

--

Therefore, the final product of this math problem is 24

Answer:

[tex]\frac{x+3}{x}[/tex]

Step-by-step explanation:

Factorise numerator and denominator

x² - 9 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

x² - 9

= x² - 3² = (x - 3)(x + 3)

x² - 3x ← factor out x from each term

= x(x - 3)

Then

[tex]\frac{x^2-9}{x^2-3x}[/tex]

= [tex]\frac{(x-3)(x+3)}{x(x-3)}[/tex] ← cancel common factor (x - 3) on numerator/denominator

= [tex]\frac{x+3}{x}[/tex]

Answer:

[tex]1[/tex] solution

Step-by-step explanation:

Let's try to solve this and see where we get.

We can add 3x to both sides of the equation to get [tex]3+4x=2[/tex].

We can then subtract 3 from both sides of the equation to get [tex]4x=-1[/tex].

We lastly divide both sides of the equation by 4 to get [tex]x=-1/4[/tex].

Because all of our steps are reversible(for instance, when we divide by 4, we can multiply(the "reverse" of division) by 4, so dividing by 4 is reversible), there is only [tex]\boxed{1}[/tex] solution, [tex]x=-1/4[/tex].

Step-by-step explanation:

Jeff makes 19 per hour and Carl makes 15 per hour.

Jeff makes more per hour, $4 more than Carl to be exact.

Jeff's constant of proportionality:   y=19/1

Carl's constant of proportionality:  y=150/10 ---> y=15

Carl's graph: For every hour he makes $15

Answer:

B

Step-by-step explanation:

|15-12|/4 = 3/4

|(-21+9)/8| = |-12/8| = 12/8 = 3/2 (Simply)

3/4 - 3/2 = -3/4

So the answer is B.
