F(x) = -9x^2 - 7x + 8
f(5) = -9(5^2) - 7(5) + 8
f(5) = -9(25) - 35 + 8
f(5) = - 225 - 35 + 8
f(50 = - 252 <==

Classify the quadrilateral. Then find the value(s) of the variable(s).​
Mkey [24]

Answer:

<h2>D</h2>

Step-by-step explanation:

The shape we see is a kite.

The measures of the triangles must add to 180°.

27 + 90 + x = 180°

117 + x = 180°

x = 63°

3 = 63°

We can also solve for 1 and 2. 2 is a right angle so 90° and 1 is a reflection of the 27° angle on the other side, so it also is 27°.

1 = 27°  2 = 90°  3 = 63°

I'm always happy to help :)

I cant figure out how to do this question plz help!
balandron [24]

Answer:

slope (m) = \frac{1 - (-5)}{2 - (-1)}

= \frac{1 + 5}{2 + 1}

= \frac{6}{3} = 2

Step-by-step explanation:

Find the slope (m) using the two points given, (-1, -5) and (2, 1):

slope (m) = \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1}

Let,

(-1, -5) = (x_1, y_1)

(2, 1) = (x_2, y_2)

Plug in the values into the equation:

slope (m) = \frac{1 - (-5)}{2 - (-1)}

= \frac{1 + 5}{2 + 1}

= \frac{6}{3} = 2
