$12/4=3 so each paint brush costs $3. $3.20/8=.40 so each pen costs $0.40. The difference between the unit price of a paint brush and unit price of pen gives you the equation 3-.40= $2.6

Answer:

$2.6

Step-by-step explanation:

12/4=3 that means each paintbrush cost $3

3.20/8=0.4 that means each pen cost $0.40

3-0.4=2.6

Task: Nonpermissible Values for Rational Expressions [30 points] Write a rational expression that has the nonpermissible values
igor_vitrenko [27]

Answer:

A rational expression that has the nonpermissible values x = 0 and x = 17 is f(x) = \frac{4}{x\cdot (x-17)}.

Step-by-step explanation:

A rational expression has a nonpermissible value when for a given value of x, the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:

f(x) = \frac{p(x)}{q(x)} (1)

Then, the factorized form of q(x) must be:

q(x) = x\cdot (x-17) (2)

If we know that p(x) = 4, then the rational expression is:

f(x) = \frac{4}{x\cdot (x-17)} (3)

A rational expression that has the nonpermissible values x = 0 and x = 17 is f(x) = \frac{4}{x\cdot (x-17)}.

Find f(1) if f(x)=5^x
dolphi86 [110]

Answer:

The value of function for x = 1 , y = 5 i.e  f(1) is 5  

Step-by-step explanation:

Given as :

f(x) = 5^{x}

Now from the function the value of y depend on the value of x

So , for x = 1

I.e  f(1) = 5^{1}

Or,  f(1) = 5

Hence The value of function for x = 1 , y = 5 i.e  f(1) is 5   Answer
