Answer:

A. The first graph

Step-by-step explanation:

When you graph these two equations on a graphing calc, you should be able to see one dotted line and one solid, as well as the solutions being mostly in the 1st quadrant.

In ΔOPQ, q = 110 inches, o = 970 inches and ∠P=167°. Find the area of ΔOPQ, to the nearest square inch.

ki77a [65]

Answer:

$Area = 12004$ square inches

Step-by-step explanation:

Given

$q = 110$

$o = 970$

$\angle P =167$

Required

The area of the triangle

To do this, we use:

$Area = \frac{1}{2} * o * q * sin(P)$

So, we have:

$Area = \frac{1}{2} * 970 * 110 * sin(167^\circ)$

$Area = \frac{1}{2} * 970 * 110 * 0.2250$

$Area = 12003.75$

Approximate

$Area = 12004$

As there are no parenthesis, Follow PEMDAS and go from left to right

14 x 13 = 182

182/9 = 20.22

20.22 + 8 = 28.22

28.22 is your answer

find an equation of the line satisfying the given conditions. write the equation using function notation. Through (-20,5) and (-

denis23 [38]

Answer:

The equation of the line using function notation is

$y=f(x)=-\frac{1}{4}x$

Step-by-step explanation:

Given points are (-20,5) and (-36, 9)

Now to find the equation of the line passes through these points

Let $(x_{1},y_{1})$ and $(x_{2},y_{2})$ be the two given points (-20,5) and (-36, 9) respectively.

To find slope

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{9-5}{-36-(-20)}$

$m=\frac{4}{-36+20}$

$m=\frac{4}{-16}$

$m=-\frac{1}{4}$

Therefore $m=-\frac{1}{4}$

The equation of the line is of thr form y=mx+c

The point (-20,5) passes through the above line and $m=-\frac{1}{4}$

$5=-\frac{1}{4}(-20)+c$

$5=5+c$

$c=0$

$y=-\frac{1}{4}x+0$

Therefore $y=-\frac{1}{4}x$

Therefore the equation of the line using function notation is

$y=f(x)=-\frac{1}{4}x$
