Solve by addition method <br>3x+y=8 <br>2x-y=7
Vinil7 [7]

Answer:

(3,-1)

Step-by-step explanation:

So we have the system of equations:

3x+y=8\\2x-y=7

As directed, add straight down. The y-variable will cancel:

5x=15

Now, divide both sides by 5. The left cancels:

x=3

So x is 3.

Now, substitute 3 for x in either of the equations:

3x+y=8

Substitute 3 for x:

3(3)+y=8

Multiply:

9+y=8

Subtract 9 from both sides:

y=-1

So, our answer is: x=3, y=-1 or (3,-1).

And we are done :)

Which are the center and radius of the circle with equation (x + 5)2 + (y - 4)2 = 9?
alina1380 [7]

Answer:

Center (-5,4) radius 3

Step-by-step explanation:

The standard equation of a circle is

(x-h)^2+(y-k)^2=r^2

where the center is (h,k) and r is the radius

so h=-5 in this case and k is 4

r^2=9 so r=3
