6 0

Answer:

<h2>x = -15 and y = -25 ⇒ (-15, -25)</h2>

Step-by-step explanation:

y=x-10\qquad(1)\\\\y=2x+5\qquad(2)\\\\\text{substitute (2) to (1):}\\\\2x+5=x-10\qquad\text{subtract 5 from both sides}\\\\2x=x-15\qquad\text{subtract x from both sides}\\\\x=-15\\\\\text{Put the value of x to (1):}\\\\y=-15-10\\\\y=-25

Sec s = 1.6948
Anastaziya [24]
That'd be true only if the value of "s" is the exact same one for both
namely  if sec(s) = cos(s)
then solving for "s"
thus

\bf sec(s)=cos(s)\qquad but\implies sec(\theta)=\cfrac{1}{cos(\theta)}&#10;\\\\\\&#10;thus\cfrac{1}{cos(s)}=cos(s)\implies 1=cos^2(s)\implies \pm \sqrt{1}=cos(s)&#10;\\\\\\&#10;\pm 1=cos(s)\impliedby \textit{now taking }cos^{-1}\textit{ to both sides}&#10;\\\\\\&#10;cos^{-1}(\pm 1)=cos^{-1}[cos(s)]\implies cos^{-1}(\pm 1)=\measuredangle s

What is the area , in square meters of the shaded part of the rectangle below
Licemer1 [7]

Answer:

123.5 m^2

Step-by-step explanation:

The area of the whole rectangle is 9 x 19 = 171 m^2

The area of the region that isn't shaded is (5 x 19)/2 = 47.5 m^2 because the height of the triangle is 5 (9 - 4) and the area of a triangle is

(height x length)/2

171 - 47.5 = 123.5 m^2
