Answer:
4
Step-by-step explanation:
The x-intercept occurs when y=0, if you think about it graphically. Plug y=o into your equation:
10x - 5(0) = 40
10x = 40 (divide each side by 10)
x=4

Answer:
16x^4+32x^3+24x^2+8x+1
Step-by-step explanation:
(2x+1)^4
(2x+1)*(2x+1)*(2x+1)*(2x+1)
Let p and c be the pieces of pie and cake respectively.
We have p+ c= 100 (because the total number of pieces of pie and cake is 100).
On the other hand, we have $4p+ $5c= $473
or 4p+ 5c= 473
p+c=100
4p+5c=473
Solving the set of equations above, we have: p= 27, c=73.
They sold 27 pieces of pie~
