In slope intercept form you already have the y-intercept and the slope. all you have to do is plot the y-intercept and then plot the slope from that point.

hope this helps :)

What multiplies to be 280 and adds to be negative 36

photoshop1234 [79]

The two numbers are -18+ 2√(11) and -18 -2√(11).

-18+ 2√(11)+ [-18 -2√(11)]= -36
[-18+ 2√(11)]* [-18 -2√(11)]= 280.

Hope this helps~

The given quadratic equation gives the parameters of the shape of the

graph of the equation.

The graph that is most likely associated with the model is; graph B

Reasons:

The given function is n(t) = -2.82·t² + 25.74·t + 60.87

by analyzing the above function, we have;

At t = 0

n(0) = -2.82 × 0² + 25.74 × 0 + 60.87 = 60.87

The x-coordinate of the maximum point is given by $\displaystyle x = -\frac{b}{2 \cdot a}$

Which gives;

$\displaystyle t = -\frac{25.74}{2 \times (-2.82)} \approx 4.564$

The maximum value of the function is therefore;

n(4.564) = -2.82 × 4.564² + 25.74 × 4.564 + 60.87 ≈ 119.61

The characteristics of the equation are;

Initial value of equation = 60.87

t-coordinate of the maximum point, t ≈ 4.564

Maximum value of the of the function = 119.61

By comparing with the given graphs, we have;

$\begin{tabular}{c|c|c|}&Graph A&Graph B\\Initial value&100&75\\t-value at max point&7&4\\Maximum value&200&125\end{array}\right]$

Therefore, the graph that will most likely be associated with the model is; graph B.

During the basketball season, Cory made 21 of the 60 baskets she attempted. Krista made

miss Akunina [59]

Cory . . . . 21/60 = 0.35 = 35 percent

Krista . . . 18/45 = 0.4 = 40 percent

Paula . . . 17/50 = 0.34 = 34 percent

From this point, I'm pretty sure you can line them up.
