I believe it would take 10 cups. The reason being 4 cups of 1/4 equals 1 so double it to 8 and add 2 more cups to make 2/4. So add 8 plus 2 and get 10.
Ughh, i’m still on this 2.
Answer:
c(n) = 4n +20
let m = c(n)
m= 4n +20
make n the subject
<u>m</u><u> </u><u>-</u><u>2</u><u>0</u><u> </u><u> </u> =n
4.
inverse function of c(n)= <u>n-20</u><u> </u>
4
It is a must that one replaces the m with the n in order to get the final answer
Let n represent the number
6/100 × n = 9
0.06 × n = 9
n = 9/0.06
n = 150
6% of $150 is $9
Answer:
1. slope: (y2-y1)/(x2-x1)
(6,38), (9,32)
(32-38)/(9-6) = -6/3 = -2
38 = -2(6) + b
38 = -12 +b, b = 50
y = -2x + 50
2a. Slope = -80, the slope means how many cars left per hour after closing. Y- intercept = 600, cars in lot during closing.
2b. use the equation: y = -80x + 600
Plug in 3 into the equation
y = -80(3) + 600, y = -240 + 600, y = 360 cars
2c. For it to have 0 cars, plug in 0 for y
0 = -80x + 600
-600 = -80x, solve for x
x = 7.5 hours
