Answer:
(-1,2) y=2 x=-1
Step-by-step explanation:
This is a system of equations and in this you see there is 3x and negative three x. To solve this you need tp get rid of one of the variables. so we can add the two equations together to get 3y=6. This means that y=2 if we divide by 3 on both sides. Then we just plug 3 in for y and we get 3x+10=7. We subtract 10 on both sides to get 2x=-3 which means x=-1.
Answer:
1%
Step-by-step explanation:
S.P of each radio=$ 2288
Total S.P=
$4576
Gain=10%
Lose=10%
C.P=
C.P=
By using the formula
C.P of one radio=
$2080
C.P of another radio=
=$2542.2
Total C.P of two radios=2080+2542.2=$4622.2
Total C.P >Total S.P
Loss=S.P-C.P
Loss=4622.2-4576=$46.2
Loss%=
Loss %=
1%
Hence, his loss 1%
