Answer:

(a) a squared + 15 squared = 17 squared

Step-by-step explanation:

The Pythagorean theorem tells you the sum of the squares of the sides is equal to the square of the hypotenuse.

a^2 + 15^2 = 17^2 . . . . . . matches the first choice

Answer:

$-\frac{5}{4x}$

Step-by-step explanation:

<h2> $\left(-5x^3\right)^3\div \left(10x^5\right)^2$ </h2><h2> $\frac{-5^3x^9}{\left(10x^5\right)^2}$ </h2><h2> $\frac{-5^3x^9}{10^2x^{10}}$ </h2><h2> $\frac{-5^3x^9}{5^2\cdot \:2^2x^{10}}$ </h2><h2> $\frac{-5x^9}{2^2x^{10}}$ </h2><h2> $\frac{-5}{2^2x}$ </h2>

$-\frac{5}{4x}$

PLEASE HELP

Alecsey [184]

Answer:

The answer to your question is letter B

Step-by-step explanation:

Process

1.- Find two points of each line

Line A (-2, 0) (-1, 2)

Line B (-1. - 5) (-6, 0)

2.- Find the slope and equation of each line

Line A

$m = \frac{2 - 0}{-1 + 2}$

$m = \frac{2}{1}$

m = 2

y - 0 = 2(x + 2)

y = 2x + 4

Line B

$m = \frac{0 + 5}{-6 + 1}$

$m = \frac{5}{-5}$

m = -1

y - 0 = -1(x + 6)

y = -x - 6

3.- Find the inequalities

Line A, we are interesteed in the lower area of the line, so the inequality is

y ≤ 2x + 4

Line B, we are also interested in the lower area of the line so the inequality is

y ≥ - x - 6
