Answer: y=6/7x-1
Step-by-step explanation:
I am assuming you want a line formula in y=mx+b
slope (y2-y1)/(x2-x1) = -7+13/-7+14 = 6/7
y+7=6/7(x+7)
y+7 = 6/7x+6
y=6/7x-1
-n/3=4
-n/3 x 3=4 x 3
-n=12
-n/-1=12/-1
n=-12
A
This is like a base form of a prime polynomial
X^2+x+1
Since y varies inversely as x , the equation is y=k/x....... Then you plug in 2 for y and 25 for x to find K....... After that you get K= 50...... Then plug in 50 for K and 40 for y then solve for x....... After that you get X= 1.25
Answer:
$650. This was the original price.
Step-by-step explanation:
Let p represent the original price.
The following expression calculates the value of p: (1 - 0.38)p = $403. Note that '1' indicates full price and that '0.38' indicates a 38% discount.
(1 - 0.38)p = $403 simplifies to (0.62)p; = $403.
Dividing both sides by 0.62 yields $650. This was the original price.
