<h2>PLEASE DOUBLE CHECK I AM SO OUT OF PRACTICE WITH THESE OMG</h2>

A. a = 25º

B. 41º

C. 41º

uh werk:

180º = 2a - 9º + 5a + 14º

180º = 7a + 5º

175º = 7a

a = 25º

180 - (5a+14) = 180 - 139 = 41

or 2a-9 = 41

The inverse of the function f(x) = { x + 10 is shown.
velikii [3]

Answer:

20

Step-by-step explanation:

f(x) = x + 10

Replace f(x) with y.

y = x + 10

Now, remember that in an inverse function you flip the x and y, so

x = y + 10

Solve for y

y = x - 10

because it's 2x... we must multiply by 2.

2y = 2x - 20

Original equation:

h(x) = 2x - 0

h(x) is 2y..

Find the real roots of the equation x^4-5x^2-36=0
Usimov [2.4K]
Treat x^4 as the square of p:  x^4 = p^2.

Then x^4 - 5x^2 - 36 = 0 becomes p^2 - 5p - 36 = 0.

This factors nicely, to (p-9)(p+4) = 0.  Then p = 9 and p = -4.

Equating 9 and x^2, we find that x=3 or x=-3.
Equating -4 and x^2, we see that there's no real solution.

Show that both x=3 and x=-3 are real roots of x^4 - 5x^2 - 36 = 0.
