Which quadratic equation has roots - 2 and 1/5 :

Sladkaya [172]

Answer:

$5 {x}^{2} \: + \: 8x \: - 2 \: = \: 0$

Step-by-step explanation:

$sum \: of roots = - 2 + \frac{1}{5} = - \frac{8}{5} \\ product \: of \: roots = - 2 \times \frac{1}{5} = - \frac{2}{5} \\ from \: general \: equation \\ a {x}^{2} + bx + c = 0 \\ {x}^{2} + \frac{8}{5} x \: - \frac{2}{5} = 0 \\ 5 {x}^{2} \: + \: 8x \: - 2 \: = \: 0$

HELP ME! In a complete sentence, describe the relationship between the three angles in the diagram below. Write and solve an equ

AlexFokin [52]

Answer:

b = 17

∠QPS = 124°

∠SPT = 17°

∠TPR = 39°

Step-by-step explanation:

The sum of the three angles shown is a linear angle, with a measure of 180°.

This fact can be used to write an equation:

(8b -12)° +b° +(2b+5)° = 180°

11b -7 = 180

11b = 187

b = 17

8b -12 = 8(17) -12 = 124

2b +5 = 2(17) +5 = 39

The value of b is 17.

The angle measures are ...

∠QPS = 124°

∠SPT = 17°

∠TPR = 39°
