You are given the dollar value of a product in 2012 and the rate at which the value of the product is expected to change during
Ray Of Light [21]

Answer:

V=r*t+D-2*r

with

V= dollar value of the product

r= value's rate of change

t= time in years (where t=0 represents 2010)

D= dollar value of product in 2012

Step-by-step explanation:

A linear equation for V in terms of t will have the following form

V=r*t+C <em>(equation 1)</em>

where r will be the rate at which the value of the value of product is expected to change, V is the dollar value of the product at the year t (being t=0 for 2010) and C is a constant number which we should be able to find knowing the value of V at some point in time.

Let's call D the dollar value of the product in 2012, we can replace this value in <em>the equation 1</em> in order to find C

V=r*t+C <em>(equation 1)</em>

D=r*2+C

C=D-2*r

So the final equation would be

V=r*t+D-2*r

with

V= dollar value of the product

r= value's rate of change

t= time in years (where t=0 represents 2010)

D= dollar value of product in 2012

(-42.27,4.4) and (2.27,3.1) what is the slope?​
kaheart [24]

Answer:

i need one more brainliest and i will level up can u gimme brainliest THXXXXXXXXX!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Step-by-step explanation:

<h2><u>HELP KEY FOR SLOPE RIGHT HERE!</u></h2>

Using the Slope Equation:

Pick two points on the line and determine their coordinates.

Determine the difference in y-coordinates of these two points (rise).

Determine the difference in x-coordinates for these two points (run).

Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

How do you calculate rise over run?

Multiply the slope by the run to calculate the rise between subsequent points. In the example, if you wanted to know the rise given a run of 10, multiply 10 times 0.6 to calculate a rise of 6. Divide the rise by the slope to calculate the run.

What does a slope of mean?

The slope of a line is the steepness of the line. There are many ways to think about slope. Slope is the rise over the run, the change in 'y' over the change in 'x', or the gradient of a line.

How do I find slope?!

<u>The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .</u>

I do not know the exact answer to ur question but this was just a help key for you. :) maybe it helped? :)

PLEASE GIVE ME BRAINLIEST! have a great day.

Someone please help!!!! 20 Points to whoever answers CORRECTLY first. <br> Thanks
ZanzabumX [31]

Answer:

3) 361/11

4) 51

Step-by-step explanation:

for both problems, they give you the length of the segment so you just add both of the segments equal to the length of the whole segment. then for whatever you find as x, plug it into the equation.

ex. 7x+1+4x-3=42

or

5x-8+7x-12=10x-2
