Solve for x and y x+y=32 x−y=8

Mathematics
1 answer:
slega [8]3 years ago
7 0

Answer:

x = 20 y= 12

Step-by-step explanation:

x+y=32

x−y=8

Add the two equations together to eliminate y

x+y=32

x−y=8

----------------

2x  = 40

Divide each side by 2

2x/2 = 40/2

x = 20

We know x so we can find y

x+y = 32

20+y = 32

20+y-20 = 32-20

y= 12

Determine the equation of a circle with a center at (–4, 0) that passes through the point (–2, 1) by following the steps below.
GaryK [48]

Answer:

Radius length: √5

Standard Form (Equation): (x + 4)^2 + y^2 = 5

Step-by-step explanation:

First we will determine the radius;

Center: (-4, 0)

Point on Circumference: (-2, 1)

d = √(-2 - (-4))^2 + (1 - 0)^2 = √(2)^2 + (1)^2

= √4 + 1 = √5

Therefore the radius is of length √5

Now the equation of a circle is in the form ((x - h)^2 + (y - k)^2) = r^2. The center is in the form (h,k) and r is the radius. Given this our equation would be (x - (-4))^2 + (y - 0)^2 = (√5)^2, or [simplified] (x + 4)^2 + y^2 = 5.
