Answer:
x = -2
Step-by-step explanation:
Step 1: Define
f(x) = -x - 5
f(x) = -3
Step 2: Substitute and Evaluate
-3 = -x - 5
2 = -x
x = -2

3x+9x=5x+4
12x=5x+4
12x-5x=4
7x=4

Not sure but I believe letter B) 3+4 is rational since the answer is 7 and 7 is a rational number and it can be expressed as a quotient.  The sum of a rational number and an irrational number is irrational. The sum of two rational numbers is rational
 
        
             
        
        
        
AC is the hypotenuse of triangle ABC.
 Because the length is 6√2 and angle A is 45 degrees, we know the length of both sides is 6.
This means AB is 6, which it the hypotenuse of triangle BCD.
Using cos(angle) = adjacent leg / hypotenuse we can find x:
cos(60) = X / 6
x = 6 * cos(60)
x = 3
 
        
                    
             
        
        
        
Hey there. The answer is A. 4/11.
To find the slope, look at the coordinates (-7, 2). Starting from there, we need to find the slope to go to the point (4, 6). We need to find the rise over run.
Look at the picture I attached. I hope you understand and find my answer helpful.
