Step-by-step explanation:
positive is at the left !
Equation: 19-2(3x-1)/5 = x + 2
Solution:
1. Find x
(5) - 2 = (x + 2) - 2
x = 3
2. Plug in X and solve
19-2(3(3)-1)/3
19-2(9-1)/3
19-2(8)/3
19-16/3
<u>3/3 = 1</u>
Answer:
P____Q____R
PR= PQ+ QR
(14x-13) = (5x-2)+(6x+1)
14x-13= 11x – 1
14x – 11x = 13–1
3x = 12
x= 12/ 3
x= 4
PR= 14x – 13 = 14 (4) – 13 = 18 – 13= 5
If you want (PQ , QR ) this is the solution
PQ =5x-2=5(4)-2=20-2=18
QR =6x+1=6(4)+1=24+1=25
I hope I helped you^_^
Legit way is vertex form
easy way is this
x value of vertex in form
f(x)=ax^2+bx+c is -b/2a
the y value is f(x value of vertex)
so
p(x)=-0.5x^2+40x-300
x value of vertex is -40/(2*-0.5)=-40/-1=40
max profit selling 40 per week
profit would be 500
