Answer: (x, y) = ( -2, -3 )
=============================================
Work Shown:
2x+y = -7
2( x ) + y = -7
2( 4+2y ) + y = -7 .... plug in x = 4+2y
2*4 + 2*2y + y = -7
8 + 4y + y = -7
5y+8 = -7
5y = -7-8 .... subtract 8 from both sides
5y = -15
y = -15/5 ... divide both sides by 5
y = -3
This y value pairs with...
x = 4 + 2y
x = 4 + 2(-3)
x = 4 - 6
x = -2
So we have (x, y) = (-2, -3) as the solution to the system.
Answer:
the last one with 2y in the denominator

I do not u derstand the question by the way you are trying to put it
Answer:
with these characteristics, place the
semi-ellipse on coordinate axes in a convenient position and draw it.
5. What is the equation of the ellipse? How wide will the canal need to be for the
Petroleum ship?
6. Now that you know which of the two alternatives provides the widest channel, consider other
factors. His department is also in charge of verifying the depth of the channel, the
amount of river traffic and other details. For example, if there was a flood in the river and
the water level will rise 10 feet, how would free space be affected? Take a decision
about which project you think would be best as far as your department is concerned and

Answer:
$4127
Step-by-step explanation:
The amortization formula is good for finding this value.
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where P is the amount invested at rate r for t years.
A = $600,000(0.055/12)/(1 -(1 +0.055/12)^(-12·20)) = $4127.32
You will be able to withdraw $4127 monthly for 20 years.
