(50-(x*50))+(40-(y*40))+20= discounted with 2 coupons
110-(z*110)= the price with the total coupon.
I believe these are the correct answers
Using the y=mx+b method and y1-y2/x1-x2
it would look like this
6-10=-4
divide
2-4=-2
and m=2 (slope)
then using y=mx+b
plug n chug
6=2(2)+b
6=4+b
b=2
thus, your equation is
y=2x+2

Answer:
<h2>c = 220</h2>
Step-by-step explanation:
f(x) = cx + d
<u>For the first equation</u>
f(50) = 27,000
Substitute the value of x that's 50 into the expression
That's
50c + d = 27,000
<u>For the second equation</u>
f(100) = 38,000
Substitute the value of x that's 100 into the expression
We have
100c + d = 38,000
Subtract the first equation from the second one to eliminate d
That's
100c - 50c + d - d = 38,000 - 27,000
50c = 11,000
Divide both sides by 50
We have the final answer as
<h3>c = 220</h3>
Hope this helps you
