Answer:
y= -x +2
Step-by-step explanation:
y-y1 = m(x-x1)
y - 0 = 1(x - (-2))
y = -x + 2)
y = x + 2.
Since $14 is the price after a 30% discount then $14 is 70% of the original price.
$14/70=x/100 (100% would be the original price)
1400=70x or 1400/70 = $20!
You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!
Y=f(x)=2x find f(x) when x=2
Plug in
f(2)=2(2) =4
Answer
4
By the looks of it the hieght is 7 and base is 6 so
A= 1/2(6)(7)
A= 1/2(42)
A= 21
