Answer:
k1 = - 0.67
k2 = -0.1
Step-by-step explanation:
if y varies directly as the square of x
mathematically,
y ∝ x²
y = kx²...................................................................... where k is the constant of proportionality.
given that y = -54 and x = 9
y = kx²
k = y/ x²
k = -54/ 9²
k = -54/81
k1 = - 0.67
also, when y = -11/3 and x = 6
k = y/x²
k = -3.667/ (6)²
k = -3.667/36
k2 = -0.1
The price would be 2.60*2.5=$6.50
Just multiply the price cause it’s by the pound and multiply it by how many pounds
8 pages per 4 hrs
2 pages per hour
2 pages per 7 hours
14 pages
It’s basically the same thing as NP so it’s D.9
Answer:
Let the x = # of pies Larry ate
Jesse ate 2x-5 pies
Total = 16
Your equation is:
x + (2x-5)=16
3x-5=16
3x=21
x = 7
Larry ate 7 pies.
