X= -2,0,2

For this question, you need to isolate all terms under the square root, so you need to move x^3 and -4x to the right. Then you would square both sides, and combine like terms.

Law of sines: How many distinct triangles can be formed for which m∠A = 75°, a = 2, and b = 3?
butalik [34]
According to the law of sines:

\frac{a}{sin(A)} = \frac{b}{sin(B)}

Using the given values, we can find the angle B and find the number of possible triangles that can be formed.

\frac{2}{sin(75)}= \frac{3}{sin(B)} \\  \\ 
sin(B)=3* \frac{sin75}{2}  \\  \\ 
sin(B)=1.45 \\  \\ 
B=sin^{-1} (1.45)

The range of sin is from -1 to 1. The above expression does not yield any possible value of B, as sin of no angle can be equal to 1.45.

Therefore, we can conclude that no triangle exists with the given conditions.

Write an equation in point slope form for the line through the given point with the given slope (5,-6) m= -0.38
tester [92]
Heeelllllloooooo! :D

Okay this is a very similar question to the one I answered earlier....

I'll show you step by step so you will be able to do this in the future on your own

(y - y₁) = m(x - x₁)     -----> point-slope form
(y + 6) = (-0.38)(x - 5)
y + 6 = -0.38x + 1.9
<u>y = -0.38x - 4.1</u><u />

There you go!
