Solve the system of equations. y = 2x y = x 2 – 15

a. (–3, –6) and (–5, –10)

b. (3, 6) and (–5, –10)

c. (3, 6) and (5, 10)

d. (–3, –6) and (5, 10)

Option D.

Step-by-step explanation:

The given system of equations is

        ....(i)

        ...(ii)

From (i) and (ii) we get

Using zero produc property we get

If x=5, then

If x=-3, then

The solutions of the given system of equations are (-3,-6) and (5,10).

Therefore, the correct option is D.

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

maya’s expression will generate the wrong sum because she violated the commutative property.
