Answer:

(0,27)

Step-by-step explanation:

x2 + 27 = 0

Solutions based on quadratic formula:

x1  

= −0 − √ 02 − 4×1×27   2×1 = 0 − 6 × √ 3 i   2 ≈ −5.196152i

x2  

= −0 + √ 02 − 4×1×27   2×1 = 0 + 6 × √ 3 i  2 ≈ 5.196152i

Fynjy0 [20]

Answer:

C. 4

Step-by-step explanation:

<u>Use the slope formula:</u>

m=\frac{y2}{x2} -\frac{y1}{x1}

m = the slope.

<u>Substitute the values into the formula:</u>

\frac{9}{3} -\frac{-7}{-1} =\frac{?}{?}

<u>Solve:</u>

\frac{9}{3} -\frac{-7}{-1} =\frac{16}{4}
