Does anyone else agree that the answer for this family of curves question is E, dy/dx = x + y?

Yes this is the correct answer. The slope field shown is the differential equation dy/dx = x+y

All points along the line x+y = k, for some constant k, will have the same tangent slope k. For example, the line x+y = 0 will have every point with tangent slope 0 for the solution y(x). It may not be 100% clear, but this graph has horizontal tickmarks on the line x+y = 0, or the tickmarks are close to being horizontal. Using geogebra, I checked the others and they produced completely different graphs, which allowed me to rule them out.

Evaluate the following functions for the given value.<br> 19. f(x) = -x3 + x2; -2

suter [353]

Answer:

12

Step-by-step explanation:

f(x) = -x^3 + x^2

Let x = -2

Evaluate the expression

f(-2) = -(-2)^3 + (-2)^2

= - (-2)*(-2) * (-2) + ( -2) * (-2)

= -(-8) + ( 4)

= 8 + 4

= 12

Please help guys this khan and litteraly have this unit test please guys illl mark brainliest

Answer:

x=36

Step-by-step explanation:

So, lets go over what we know:

16 is equal to 4/9ths of x.

As a equation, this looks like:

$16 = \frac{4}{9}x$

We can begin to solve for x by multiplying both sides by the denominator, 9, which gets us:

$16*9 = 4x$

=

$144 = 4x$

Then we can divide by the coefficent of x, which is 4, to get our answer:

$\frac{144}{4} = x$

=

$36=x$

This is our answer! Hope this helps! :3

F(x)=2x/3x^2-3 what is the domain of the function?

konstantin123 [22]

Answer:

Step-by-step explanation:

$f(x) = \frac{2x}{3x^2 - 3} \\\\ Domain: \\ 3x^2 - 3 ≠ 0 \\ 3x^2 ≠ 3 \\ x^2 ≠ 1 \\ x ≠ \pm 1$

D = {x E R/ x ≠ 1 and x ≠ - 1}

I Hope I've helped you.
