<h3>
Answer: (3, 0)</h3>
=================================================
Explanation:
Let's isolate x in the first equation.
x-2y = 3
x = 3+2y
Then we'll plug this into the second equation
Afterwards, solve for y.
2x + 4y = 6
2(3+2y)+4y = 6
6+4y+4y = 6
8y+6 = 6
8y = 6-6
8y = 0
y = 0/8
y = 0
Use this to find x.
x = 3+2y
x = 3+2(0)
x = 3
The solution is therefore (x,y) = (3, 0)
If you were to graph both lines, then they would intersect at the location (3,0).
-----------------------------
Checking the answer:
Plug x = 3 and y = 0 into the first equation.
x-2y = 3
3-2(0) = 3
3 - 0 = 3
3 = 3 that works
Repeat for the other equation
2x+4y = 6
2(3) + 4(0) = 6
6 + 0 = 6
6 = 6 that works as well
Both equations are true when (x,y) = (3,0).
The solution is confirmed.
Answer:
m>11
Step-by-step explanation:
2(m+3)<-5+3m
2(m+3)>3m-5
2m+6>3m-5
6<3m-5-2m
6<m-5
6+5<m
11<m
m>11
Carey earns c hourly
Anderson earns $6 hourly which is also 1+ c/2
So, 6=1+c/2
12=2+c
c=$10
Carey earns $10 hourly
I believe the correct answer from the choices listed above is the third option. The polynomial expression that represents the area of the outermost square tile would be <span>x^2 + 6x + 9. The area of a square is calculated by the square of its side and the side of this square is given as x+3.
A = (x+3)^2 = x^2+6x+9</span>
