Answer:
A. there is exactly one solution. the solution set is {(2, 0)}.
Step-by-step explanation:
3x + 8y = 6
3x - 8y = 6
when we add these 2 equations, we get
6x + 0 = 12
6x = 12
x = 2
now we use one of the original equations to get y :
3×2 + 8y = 6
6 + 8y = 6
8y = 0
y = 0
Perimeter of a rectangle:
P=2I+2W=2(I+w)
But if the length and width of a rectangle are both double, then we would have:
Length=2I
width=2w
Therefore, its perimeter would be:
P=2(2I+2w)=4(I+w)
the old perimeter was P=2(I+w) and the new perimeter is P=4(I+w)=2[2(l+w)]
There the perimeter is twice as great.
Answer: C) the perimeter is twice as great.

Answer:
The weekly sales must be $12,600
Step-by-step explanation:
if their pay is the same, the equations have to be equal
amelia = jayden
185 +.095x = 311 +.085x
subtract .085x from each side
185 +.095x-.085x = 311 +.085x-.085x
185+.01x = 311
subtract 185 from each side
185-185+.01x = 311-185
.01x = 126
divide by .01
.01x/.01 = 126/.01
x = 12600
