Step-by-step explanation:

Amanda's unit rate would be

s=50m

while Mary's is

s=60m

60-50 is 10, meaning the answer would be D.

Mary saves $10 more than Amanda every month.

Hope this helps! :)

Hi there!

We can find an equation that models Amanda's savings using the equation:

y = km, where:

k = rise / run (Amount/months)

Plug in a set of values from the table:

k = 100/2 = 50

y = 50m

We know that Mary saves y = 60m dollars a month, so we can determine the correct comparison by plugging in a value of 1 month into both equations:

Amanda:

y = 50(1) = $50

Mary:

y = 60(1) = $60

The difference between Mary's and Amanda's savings is $60 - $50 = $10, so each month, Mary saves $10 more than Amanda.

The correct answer is D.

The slope of the line is 2/3.

Here,

Graph of a line on coordinate plane. Axes are labeled x and y.

Three points are with ordered pairs (2, 3), (5, 5), and (8, 7) and the line passes through these three points.

We have to find the slope of the line.

What is the slope of the line?

Let two points (x₁, y₁) and (x₂, y₂) are on the line, then slope of the line is calculated as;

[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Now,

Three points are passes through the line are (2, 3), (5, 5), and (8, 7).

To find the slope, Let any two point from three given points.

Let (2, 3) and (5, 5) on the line.

Hence, Slope is calculated as,

⇒ [tex]m = \frac{5-3}{5-2} = \frac{2}{3}[/tex]

Therefore, The slope of the line is 2/3.

Answer:

y = -8

Step-by-step explanation:

When y = -2/5, the slope is 0.

Seeing this, we can make the equation the same as the y-value of the point given.

Hence,

y = -8

Answer:

38-2(5) = 28

So the temperature would be 28 degrees celsius

Answer: Teperature at 5PM will be 28°C

Ok so at 12 its 38°C

And it dcreases at 2°C an hour, we need to find the teperature at 5 o clock.

The number of hours between 12 and 5 mutiplied by 2 will give us the trail in temperature and then subtracting the trail i temperature witht the temperature a 12 will give us the teperature at 5 o clock.

SO,

hours between 12 PM and 5 PM is 5 hours

As, the temperature decreases at a uniform rate of 2°c per hour

⇒5×2°C

⇒10°C

Now the temperature at 5 PM will be 38°C-10°C=28°C
