Answer:
We can have several equivalents.
It can be 1/784, 28^(-2), or 1/ (28^2)
Step-by-step explanation:
4^(-2) * 7^(-2) = (4*7)^(-2) = 28^(-2)
or 1 / (28^2) is another equivalent.
4^(-2) * 7^(-2) = 28^(-2)
4^(-2) * 7^(-2) = = 1/784
<span>diff(x^2-11*x+24, x) = 2*x - 11
solve(2*x-11 = 0)
x = 11/2
y = (11/2)^2-11*(11/2)+24 = - 25/4
Vertex = (11/2, - 25/4)</span>
Answer:
828
Step-by-step explanation:
X=number of plates
y=number of cups
4x+5y=25.25
7x+3y=25.50
Add the two equations together:
11x+8y=50.75
11x=50.75-8y
x=
Plug x into the first equation:
4x+5y=25.25
4(
) = 25.25
= 25.25
= 25.25
203-32y = 277.75
-32y=74.75
32y=-74.45
y=2.34 (rounded to nearest hundredth)
The price of a plate is $2.34
