Answer:
x=2
Step-by-step explanation:

Add 14 to both sides

Square root it
x=2
 
        
             
        
        
        
It's an isosceles triangle, therefore m∠B = m∠C.
We have the equation:
2x + 10 = 3x - 5      <em>subtract 10 from both sides</em>
2x = 3x - 15     <em>subtract 3x from both sides</em>
-x = -15     <em>change the signs</em>
x = 15
m∠B = (2x + 10)°
m∠B = (2 · 15 + 10)° = (30 + 10)° = 40°
We know, the sum of measures of a tringle is equal 180°.
m∠A + m∠B + m∠C = 180°
m∠B = m∠C = 40°
<h3>Answer: ∠B = 40° and ∠C = 40°</h3>
 
        
             
        
        
        
Answer:
-3
Step-by-step explanation:
slope formula is y2-y1 over x2-x1
if we plug in the values and solve, that gets you -3.
 
        
                    
             
        
        
        
Answer:
A is f ", B is f, C is f '.
Step-by-step explanation:
Your answer is correct.  B is the original function f.  It has a local maximum at x=0, and local minimums at approximately x=-3/2 and x=3/2.
C is the first derivative.  It crosses the x-axis at each place where B is a min or max.  C itself has a local maximum at approximately x=-3/4 and a local minimum at approximately x=3/4.
Finally, A is the second derivative.  It crosses the x-axis at each place where C is a min or max.
