Answer:
4x + 7y
Step-by-step explanation:
4(x+y) + 3y
Distribute
4x+ 4y+ 3y
add like terms
4x + 7y
By looking at the graph, we can see that the shape is a quarter of a circle.
The area of a circle is:

So, this "quarter circle" is:

R is the radius (the diagram shows the radius is 8), so we can now find the area:

The area is 8π.
If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3

Answer:

Step-by-step explanation:
The slope-intercept form:

m - slope
b - y-intercept
We have

Parallel lines have the same slope. Therefore we have the equation:

The line passes through the point (-3, -5). Put the coordinates of the point to the equation and solve it for b:

<em>add 1.8 to both sides</em>

Finally we have:
