The answers tell you the y-intercept is zero, so all you need to do is choose the appropriate slope. Since y/x = -4, ...
.. selection A is appropriate.

What is this I'm lost

Ghella [55]

Basically you have to convert the equalities in each box.
I'll help you figure out what the equalities are and hopefully you can figure it out from there.

Milli= .001
Centi= .01
Deci= .1
Unit base=1
Deka= 10
Hecto= 100
Kilo= 1000

In the first box, it asks for you to convert a millimeter into a meter

1mm=.001m

If you have any more trouble, please message me. I'd be happy to help

Answer:

Step-by-step explanation:

treadmills=x

stattionary bikes=x+7

equation

25=x+x+7

25=2x+7

solve for x

2x=18

x=9

treadmills=9

stationary bikes=9+7

=16

write the equation of the line that passes through the points (-4,4) and (6,9) and figure out what y=mx+b for this equation woul

jeka57 [31]

Hello there! So, y = mx + b is in slope-intercept form, where m represents the slope, b represents the y-intercept, and y and x remain unfilled. First off, let's solve for the slope. The formula for slope is y2 - y1 / x2 - x1, where you subtract the first x and y coordinates from the second x and y coordinates. So it would be formed like this:

9 - 4 / 6 - (-4)

Let's subtract. 9 - 4 is 5. 6 - (-4) is 10. 5/10 is 1/2 in simplest form. The slope for this equation is 1/2. Now, let's find the y-intercept. We will find that by plugging one of the points into the equation and solving for b. The x and y coordinates will be filled in by that coordinate. Let's use (-4, 4) for this problem. We will also plug in the slope. In this case, the problem will look like this:

4 = (1/2)(-4) + b

Now, let's multiply 1/2 and -4 to get -2. Now, to get b by itself, subtract 2 to both sides to isolate the b. -2 + 2 cancels out. 4 + 2 is 6. b = 6. There. The equation of the line in slope-intercept form is y = 1/2x + 6.

Baxter is thinking about buying a car. The table below shows the projected value of two different cars for three years.

saw5 [17]

Car 1: It is an exponential function that is given as P = 18,500 (0.9595)ⁿ and the price after 10 years is $12,235.5.

Car 2: It is a linear function that is given as 2000x + 3y = 55500 and the price after 10 years is $11,833.33.

And Yes, there is a significant difference.

<h3>What is a function?</h3>

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

Baxter is thinking about buying a car. The table below shows the projected value of two different cars for three years.

Car 1 (value in dollars)

Year 1: 18,500

Year 2: 17,390

Year 3: 16,346.60

Car 2 (value in dollars)

Year 1: 18,500

Year 2: 17,500

Year 3: 16,500

The exponential function describes car 1.

Then the function will be

$\rm P = 18500\times (0.95995)^n$
