Answer:
7 fancy shirts and 5 plain shirts
Step-by-step explanation:
f and p are the numbers of fancy and plain shirts
f+p = 12
p = 12-f
20f + 10p = 190
20f + 10(12-f) = 190
20f + 120 - 10f = 190
10f = 70
f = 7
p = 12-f = 5
Answer:
5:1
Step-by-step explanation:
Divide both numbers by a common factor to reduce it. The common factor is 3.
15/3 = 5
3/3 = 1
That’s a black screen luv
F : R -> R, f(x) = ( 2x - 3)( x - 3 ) => f(x) = 2x^2 - 9x + 9;
The axis of symmetry is x = - b / (2a) => x = 9 / 4.
