Find the x-intercepts for the parabola defined by the equation below. y = x2 + 9x + 14

faltersainse [42]

Answer:

x - intercepts are (-7,0) and (-2,0)

A is the correct option.

Step-by-step explanation:

We have been given the equation of the parabola $y=x^2+9x+14$

For x- intercept, y = 0

$0=x^2+9x+14$

We can split the middle term as 9x = 7x +2x

$x^2+7x+2x+14=0$

Now take GCF

$x(x+7)+2(x+7)=0$

Factored out the common term

$(x+7)(x+2)=0$

Apply the zero product property

$(x+7)=0,(x+2)=0$

Solve for x

$x=-7,-2$

Hence, x - intercepts are (-7,0) and (-2,0)

A is the correct option.

Anyone know the answer to this question???

They want you to write the number in index form.

The number is 5N^2, where N = 3 x 5^2 x x^3

So:

5N^2 = 5 x (3 x 5^2 x x^3)^2

= 5 x (3^2 x 5^4 x x^6)

= 3^2 x 5^5 x x^6

or a bit neater looking: 3² ₓ 5⁵ ₓ x⁶
