Answer:
The correct options are,
x = -2 and x = 3
Step-by-step explanation:
It is given that,
x² - x - 6 = 0
<u>To find the solution of given equation</u>
x² - x - 6 = 0 can be written as
x² + 2x - 3x - 6 = 0
x(x + 2) - 3( x + 2) = =
(x + 2)(x - 3) = 0
Either (x + 2) = 0 or (x - 3) = 0
If (x + 2) = 0 then x = -2
If (x - 3) = 0 then x = 3
Therefore the correct options are,
x = -2 and x = 3
Answer:
8.090169944 or rounded 8.1
Step-by-step explanation:
Use SOH CAH TOA
Look at x and where it is and what you have.
First thing is to get an angle to use, 36, then to set up your equation.
___(36)=___
Figure out what you have.
You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.
You set up your equation using COS, as you are using CAH.
Cos(36)=x/10
X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse
Switch it around to make it equal to x
10*Cos(36)=x
You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.
Round however is needed.
Answer:
D
Step-by-step explanation:
We really don't care about 
because it's not something the question wants, so let's just focus on 
.
reflected across the 
-axis is the same as flipping the sign of the 
coordinate. So, 
.
So, the answer is 
and we're done!
