Answer:

$-\frac{7}{8}$

Step-by-step explanation:

I'm assuming you're asking for the slope of the line that passes through the two given points. To find this, use the slope formula: $\frac{y_2-y_1}{x_2-x_1}$ .

Substitute the point coordinates into the formula.

$\frac{-2-5}{6-(-2)} \rightarrow\frac{-7}{8}$

The slope of the line is -7/8.

What are the coordinates of the vertex for f(x) = 3x2 + 6x + 3? (−1, 0) (3, 6) (0, −1) (6, 3)

larisa [96]

Answer:

The vertex is the point $(-1,0)$

Step-by-step explanation:

we have

$f(x)=3x^{2} +6x+3$

we know ow that

The equation of a vertical parabola into vertex form is equal to

$y=a(x-h)^{2}+k$

where

(h,k) is the vertex of the parabola

Convert the equation into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)-3=3x^{2} +6x$

Factor the leading coefficient

$f(x)-3=3(x^{2} +2x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$f(x)-3+3=3(x^{2} +2x+1)$

$f(x)=3(x^{2} +2x+1)$

Rewrite as perfect squares

$f(x)=3(x+1)^{2}$

therefore

the vertex is the point $(-1,0)$

Wich one is bigger 3/3 or 7/8

MrRissso [65]

3/3=1 and 7/8 is < 1 so 3/3 is bigger

Not sure how to do this, I will give Brainiest for step-by-step instructions.

Mkey [24]

Find 2 coordinates on the graph : (0, -20) and (10, 10)

Slope = (10 - (-20) ) / (10 - 0) = 30/10 = 3

Slope = 3

y-intercept = (0, - 20)

Equation : y = 3x - 20

Since the right hand side is shaded, the equation is y > 3x - 20.
