2500
So if we added both equations together so 2x+3x =5x and 3y+2y =5y and 1200+1300=2500 so 5x+5y=2500

Answer:

1385.4 sq yards

Step-by-step explanation:

The diameter is twice the radius. 42 divided by two is 21.

The area of a circle is found with the formula Pi *r^2.

21^2 * pi is approximately equal to 1385.4 sq yards

A line contains the points (-3, 4) and (7, -1). Calculate the equation of the line in the form
ad-work [718]

Answer:

y=-\frac{1}{2}x+\frac{5}{2}

Step-by-step explanation:

First we need to find the slope of the line.  We can plug in both coordinates in to the slope formula.

The slope formula is:

m=\frac{y2-y1}{x2-x1}

So I will use (-3,4) as the first coordinate, and (7,-1) as the second coordinate.

x₁ = -3

y₁ = 4

x₂ = 7

y₂= -1

I will plug in these values to find the slope.

m=\frac{y2-y1}{x2-x1}\\\\m=\frac{-1-4}{7-(-3)}\\\\m=\frac{-5}{10}\\\\m=-\frac{1}{2}

Now that we know the slope is -1/2, we can plug in the slope and a point into the point slope equation.  Then we can solve for y.

y-y_{1} =m(x-x_{1} )\\\\y-4==-\frac{1}{2}(x-(-3))\\\\y-4=-\frac{1}{2}x-\frac{3}{2}\\\\ y=-\frac{1}{2}x+\frac{5}{2}

I have attached an image of what this graph should look like.  Since the slope is -1/2, the y value should decrease by 1/2 every time you move over by 1 on the x axis.  And since the equation says "+5/2" we know we have to shift the graph up by 5/2.  The y-intercept will be 5/2.

I added another image that shows how to graph an equation using the equation y=mx+b

5. Suppose that the volumes of four stars in the Milky Way are 2.7 × 1018 km3, 6.9 × 1012 km3, 2.2 × 1012 km3, and 4.9 × 1021 km
shtirl [24]
To be able to arrange the volumes from least to greatest we must be mindful that the exponent of 10 in the scientific notation should be arranged from least to greatest also. If two or more items have the same exponents in the 10 of the scientific notation, we use the base for comparison. For this item, the arrangement should be        
              2.2x10^12 km³, 6.9x10^12 km³, 2.7x10^18 km³, and 4.9x10^21 km³
Thus, the answer to this item is letter B.
