1. Find Slope
m = y2-y1/x2-x1
m = -6 - 5/2-4
m = -11/-2
m = 11/2
2. Write equation with know information
y = mx + b
y = 11/2x + b
3. Choose any of the two points (doesn’t matter which in you choose) and replace the x and y value into the equation
y = 11/2x + b (4,5)
5 = 11/2(4) + b
5 = 22 + b
Use algebra and solve for b
5 - 22 = b
b = -17
State all the information you know
m = 11/2 b = -17
Write the equation
y = 11/2x - 17
Answer:
a) R = 3.6
b) A = 2
Step-by-step explanation:
To find the value, start by modeling the inverse proportionality by using the base equations with the original givens.
y = k/x
12 = k/1.5
18 = k
Now we use that to model the equation
R = 18/A
And we can now use that to solve parts a) and b)
a)
R = 18/A
R = 18/5
R = 3.6
b)
R = 18/A
9 = 18/A
2 = A
That is the correct expression but not the correct answer.
504 divided by 3 is 168.
I hope this helped! :-)
Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>32</u></em></h2>
Step-by-step explanation:
4x - 7 - 3x + 4 =25
=> 4x - 3x = 25 + 7
=> <em><u>x = 32 (Ans)</u></em>
