Answer:

4

Step-by-step explanation:

The given equation of circle is:

(x+2)^2 +(y-3)^2 =4

(x+2)^2 +(y-3)^2 =2^2

Equating it with:

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

We find:

r^2=2^2

\therefore r=2

Radius of the circle = 2 units

Therefore,

Diameter of the circle = 2*2= 4 units

Which represents the solution(s) of the system of equations, y = x2 – 2x – 15 and y = 8x – 40? Determine the solution set algebr
almond37 [142]

Answer:

(5, 0 )

Step-by-step explanation:

Given the 2 equations

y = x² - 2x - 15 → (1)

y = 8x - 40 → (2)

Substitute y = x² - 2x - 15 into (2)

x² - 2x - 15 = 8x - 40 ( subtract 8x - 40 from both sides )

x² - 10x + 25 = 0 ← in standard form

(x - 5)² = 0 ← in factored form, thus

x - 5 = 0 ⇒ x = 5

Substitute x = 5 into (2) for corresponding value of y

y = 8(5) - 40 = 40 - 40 = 0

Solution is (5, 0 )
