Answer:

-2/35

Step-by-step explanation:

Slope y-intercept form : y = mx + b

Here m is the slope and b is the y-intercept

Write the given equation in slope y-intercept form.

$\sf \dfrac{2}{7}x + 5y = 15\\\\$

$\sf 5y = \dfrac{-2}{7}x + 15\\\\ y =\dfrac{-2}{7*5}x + \dfrac{15}{5}\\\\ y = \dfrac{-2}{35}x + 3\\\\ \boxed{\bf Slope = \dfrac{-2}{35}}$

Answer:

$a=10.88\pi$

Step-by-step explanation:

using the formula below, the central angle is 20° (bc 360-180-160=20)

radius is 14 (28/2=14)

$\frac{20}{360} =\frac{a}{\pi r^2} \\ \frac{1}{18} =\frac{a}{\pi 14^2}$

$\frac{1}{18} =\frac{a}{196\pi}$

$a=\frac{1*196\pi}{18} \\a=1*10.88\pi\\a=10.88\pi$

Answer:

$x = - 4 \\ x = - 7$

Step-by-step explanation:

$x {}^{2} + 28 = - 11x \\ x {}^{2} + 11x + 28 = 0 \\ x {}^{2} + 7x + 4x + 28 = 0 \\ x(x + 7) + 4(x + 7) = 0 \\ (x + 4)(x + 7) = 0 \\ \\ x = - 4 \: \: \: \: \: \: \\ \: x = - 7$
