X-4y=-12
4x-y=12
eliminate y's
multily 2nd equaiton by -4 and add to top one
x-4y=-12
<u>-16x+4y=-48 +
</u>-15x+0y=-60
-15x=-60
divide both sides by -15
x=4
sub back
x-4y=-12
4-4y=-12
minus 4 both sides
-4y=-16
divide both sides by -4
y=4
x=4
y=4

Answer:
Step-by-step explanation:
The opposite side to angle B is 4. It is the line AC. AC is not connected in any way to <B
The adjacent side is one of the two sides making up <B. It is 3.
Tan(B) = opposite / adjacent
Tan(B) = 4/3
<B = tan-1(4/3)
<B = 53.13

Answer:
$2327.5
Step-by-step explanation:
The stock of company A lost 2% today .
Let the price of the stock at the beginning of the day be A.
Therefore, a 2% loss of A = $46.55
That’s
2% /100% x A = $46.55
0.02 x A = $46.55
Divide both sides by 0.02
0.02/0.02 x A = $46.55/0.02
A = $2327.5
The price of stock at the beginning of the opening day was $2327.5
