Do this: 3k - 8 + 2k

Then: k - 8 = 0 (Subtract the K's from both sides)

Finally: k = 8 (Add the 8 from both sides)

Your answer would be "k = 8"

The cost of a floral bouquet after a discount is applied is represented by the function below, where x represents the number of
galina1969 [7]

The average rate of change over the interval (12,24) is 2.17

Explanation:

Given that the cost of a floral bouquet after a discount is given by the function f(x)=2.17x-10.00

We need to determine the average rate of change over the interval (12,24)

The average rate of change can be determined using the formula,

\frac{f(b)-f(a)}{b-a}

where a=12 and b=24

Substituting the value of a and b in the function, we get,

f(12)=2.17(12)-10.00

        =26.04-10.00

        =16.04

f(24)=2.17(24)-10.00

        =52.08-10.00

        =42.08

Hence, substituting these values in the formula, we get,

\frac{f(b)-f(a)}{b-a}=\frac{42.08-16.04}{24-12}

Simplifying, we get,

\frac{f(b)-f(a)}{b-a}=\frac{26.04}{12}

Dividing, we have,

\frac{f(b)-f(a)}{b-a}=2.17

Thus, the average rate of change over the interval (12,24) is 2.17

How do I solve the inequality?
timurjin [86]
Hello,

if 20+1/2x>0 then |20+1/2x|=20+1/2x
thus 20+1/2x>6
==> 1/2x>6-20
==>x>2*(-14)
==>x>-28

if 20+1/2x<0 then |20+1/2 x|=-(20+1/2 x)
thus -(20+1/2 x)>6
==>20+1/2x<-6
==>1/2 x <-6-20
==>x<2 *(-26)
==>x< -52

Sol =(-infinity, -52[ ∪ ] -28, +infinty)

What is the value of x?<br><br> 6(−3−x)−2x=14<br><br> Enter your answer in the box.
olchik [2.2K]
For this we would first simplify using order of operations.
6(-3-x) - 2x = 14 ------> Distribute
-18 -6x - 2x = 14 ------> Combine Like Terms
-8x - 18 = 14 Now we want to isolate x!
-8x - 18 = 14 ------> Add 18 to both sides.
-8x = 32 ------> Divide both sides by -8.
x = -4
Hope this helps!
