If this is represented by a linear function, then we know that the amount of money decreases at an unchanging amount. Knowing this, and knowing that on day 8, she had 2400, we simply just add 2400 to 8 100's:

2400 + 8*100 = 2400 + 800

Carrie initially had $3200, or Option C.

Answer:

$3,200

Step-by-step explanation:

slope =  

1,600 - 2,400

16 - 8

= -100

y = mx + b

2,400 = -100(8) + b

b = 3,200

thus,

y = mx + b

y = -100x + 3,200

y = -100(0) + 3,200

y = 3,200

Find an equation equivalent to r = 10 sinθ in rectangular coordinates
Flura [38]

Answer:

x^{2} + y^{2} - 10\cdot y = 0

Step-by-step explanation:

The following expressions are used to transform from polar into rectangular form:

r = \sqrt{x^{2}+y^{2}}

\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}

Now, the variables are substituted and equation is finally simplified:

\sqrt{x^{2}+y^{2}} = 10\cdot \frac{y}{\sqrt{x^{2}+y^{2}} }

x^{2}+y^{2} = 10\cdot y

The equivalent equation in rectangular coordinates is:

x^{2} + y^{2} - 10\cdot y = 0

If x -1 = 2y/3,then y=​
earnstyle [38]

Answer:

The answer is

<h2>y =  \frac{3x - 3}{2}</h2>

Step-by-step explanation:

<h3>x - 1 =  \frac{2y}{3}</h3>

To solve for y cross multiply

That's

3( x - 1) = 2y

2y = 3x - 3

Divide both sides by 2 to make y stand alone

That's

<h3>\frac{2y}{2}  =  \frac{3x - 3}{2}</h3>

We have the final answer as

<h3>y =  \frac{3x - 3}{2}</h3>

Hope this helps you
