Two separate linear functions are expressed by the graph and by the equation. Select all that apply.

Andre45 [30]

Answer:

First option: The slope is negative for both functions.

Fourth option: The graph and the equation expressed are equivalent functions.

Step-by-step explanation:

<h3> The missing graph is attached.</h3><h3> </h3>

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

Given the equation:

$y=-4x-4$

We can identify that:

$m=-4\\b=-4$

Notice that the slope is negative.

We can observe in the graph that y-intercept of the other linear function is:

$b=-4$

Then, we can substitute this y-intercept and the coordinates of a point on that line, into $y=mx+b$ and solve for "m".

Choosing the point $(-2,4)$ , we get:

$4=m(-2)-4\\\\4+4=-2m\\\\m=-4$

Notice that the slope is negative.

Therefore, since the lines have the same slope and the same y-intercept, we can conclude that they are equivalent.

Evaluate the double integral ∬R(2x−y)dA, where R is the region in the first quadrant enclosed by the circle x^2+y^ 2= 4 and the

frez [133]

Answer:

Step-by-step explanation:

We are to integrate the function

$f(x,y) = 2x-y$

over the area enclosed by the circle

$x^2+y^2 =4 \\x=0\\y=x$

Convert into polar coordinates

$dA=rdr dt$

x=rcost and y = rsint

Since the lines are x=0 and y=x we find that t varies from 0 to pi/4

$2x-y =2rsint-rcost$

Double integral will become now

$\int\limits^\frac{\pi}{4} _0 \int\limits^2_0 2rcost -rsint dt\\=\int\limits^\frac{\pi}{4} _0 r^2 cost -r^2sint /2 dt\\= r^2 sint - r^2 cost/2$

(since variables are independent here)

Substitute for r and t

4 sin pi/4 -2 cospi/4

= $\sqrt{2}$
