Answer:

Q(-10) = 299

Step-by-step explanation:

$Q(x) = 3x^{2} - 1$ $Q(-10) = 3(-10)^{2} - 1$

$Q(-10) = 3(100) - 1$ (-10 to the second power is 100 (negative times a negative equals a positive)

$Q(-10) = 300 - 1$ 3 times 100 equal 300

$Q(-10) = 299$

which equations represent in point slope form, the line that passes through the points (-3,2) and (0,0) ?

alexandr1967 [171]

Answer: First Option is correct.

Explanation:

Since we have given that

there are two points from which the line is passing through :

$(-3,2)\ and\ (0,0)$

We have to use the two point slope form .

As we know the " Two point slope form" i.e.

$y-y_0=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Here,

$x_1=-3\\\\x_2=0\\\\y_1=2\\\\y_2=0$

So, our equation becomes,

$(y-2)=\frac{0-2}{0+3}(x+3)\\\\(y-2)=\frac{-2}{3}(x+3)$

Hence, First Option is correct.
