Answer:
x = -2
y = -5
Step-by-step explanation:
We can solve this algebraically (substitution or elimination) or graphically. I will be using elimination:
Step 1: Add the 2 equations together
-8y = 40
y = -5
Step 2: Plug <em>y </em>into an original equation to find <em>x</em>
-3(-5) + 10x = -5
15 + 10x = -5
10x = -20
x = -2
And we have our final answers!
Answer:
D

Answer:
luxury=15
sports cars 25
Step-by-step explanation:
Step one:
let the luxury cars be x
and the sports cars be y
the objective function is
maximize
15000x+16000y=625000------1
the constraints are
1. Man-hours
1600x+1500y=61500-----------2
Step two:
the system of equation for the situation is
15000x+16000y=625000------1
1600x+1500y=61500-----------2
let us reduce both equation
divide equation 1 be 1000
and equation 2 by 100 we have
15x+16y=625--------1 x15
16x+15y=615--------2 x16
225x+240y=9375
-256x+240y=9840
=-31x+0=-465
31x=465
x=465/31
x=15
put x=15 in 15x+16y=625 we have
15(15)+16y=625
225+16y=625
16y=625-225
16y=400
y=400/16
y=25
