The GCF is the biggest number that goes into all of the terms. The biggest coefficient for x and y multiplied together. The GCF in these answers is to the left of the parenthesis.
If you multiply the GCF into he parenthesis you will get the original equation. On the other hand, the biggest number that goes into all of the terms is 3x * 1y = 3xy
Now you know the GCF, multiply it out in both of those answers and pick the one that is the original equation
Answer:

Step-by-step explanation:

For the y to cancel out, you would have to divide y by 5. Whenever you do one thing to a side, you <u><em>have</em></u> to do the same on the other side. Once you do so, you'll get :

Answer: Our required equation would be 
Step-by-step explanation:
Since we have given that
Amount that Anderson earns per hour = $6
According to question, Anderson earns $1 more than half of Carey's hourly rate.
Let the hourly rate of Carey be 'c'.
So, it becomes,

And the value of c would be

Hence, our required equation would be 
If they take 5 days to drive 679 miles to Seattle. Then the number of miles that they drive each day will be 135.8 miles per day.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
They take 5 days to drive 679 miles to Seattle.
Then the number of miles that they drive each day will be
→ 679 / 5
→ 135.8 miles per day.

The easiest way is to try the point (-4,1), that is, x=-4, y=1,
to see which equation works.
b works.
The usual way to do it is to find the equation of the circle
standard form of a circle is (x-h)²+(y-k)²=r², (h,k) are the coordinates of the center, r is the radius.
in this case, the center is (-2,1), so (x+2)²+(y-1)²=r²
the given point (-4,1) is for you to find r: (-4+2)²+(1-1)²=r², r=2
so the equation is (x+2)²+(y-1)²=2²
expand it: x²+4x+4+y²-2y+1=4
x²+y²+4x-2y+1=0, which is answer b.
