Answer: a=-1

Step-by-step explanation:

-11-5a=6(5a+4)

-11-5a=30a+24

-11-5a-30a=24  

-5a-30a=24+11

-35a=35            

a=-1

-11-5a=6(5a+4) .... Distribute the 6 to 5a and 4
-11-5a=30a+24 .... Subtract 30a from both sides
-11-5a-30a=24  .... Add 11 from both sides
-5a-30a=24+11 .... Add like terms
-35a=35            .... Divide -35a from both sides
a=-1                  .... Final answer

Let f be a differentiable function such that f(0) = -5 and f'(x) is less than or equal to 3 for all x. Of the following, which i
stepladder [879]
E) 2 
 Remember that the first derivative of a function is the slope of the function at any specified point. We've been told that f(0) = -5 and that f'(x) is always less than or equal to 3. So let's look at the available options and see what the average slope would have to be in order to get the specified value of f(2).
 A) -10: (-10 - -5)/(2 - 0) = -5/2 = -2.5
 B) -5: (-5 - -5)/(2 - 0) = 0/2 = 0
 C) 0: (0 - -5)/(2 - 0) = 5/2 = 2.5
 D) 1: (1 - -5)/(2 - 0) = 6/2 = 3
 E) 2: (2 - -5)/(2 - 0) = 7/2 = 3.5 
 Now taking into consideration the mean value theorem, the value of the function f'(x) has to have the value equal to the average slope between the two points at at least one point between the two given values. For options A, B, C, and D it's possible for f'(x) to return values that make that slope possible. However, for option E, the mean value theorem indicates that f'(x) has to have the value of 3.5 for at least 1 point between x=0 and x=2. And since we've been told that f'(x) is less than or equal to 3 for all possible values of x, that is in conflict and f(2) can not have the value of 2.

Given Angle 1 = Angle 2,<br> find x.
drek231 [11]

Answer:

x = 6

Step-by-step explanation:

Given ∠ 1 = ∠ 2 then the segment is an angle bisector and the ratios of sides to base are equal, that is

\frac{3}{x-4} = \frac{x}{4} ( cross-  multiply )

x(x - 4) = 12 ← distribute left side

x² - 4x = 12 ( subtract 12 from both sides )

x² - 4x - 12 = 0 ← in standard form

(x - 6)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 2 = 0 ⇒ x = - 2

However, x > 0 , thus x = 6
