Answer:

9.6 miles per hour

Step-by-step explanation:

First find the unit rate.

25/4= 0.16 miles per minute

Then multiply by 60 ( which we know theres 60 minutes in a hour.)

0.16x60=9.6

F(x) = 2x^2 – 3x – 9<br> g(x) = 4x^2 - 9<br> Find ( f/g)(x).
Tomtit [17]

Answer:

(f/g)x = (x - 3)/(2x - 3)

Step-by-step explanation:

Try and see if f(x) can be factored.

g(x) = (2x - 3) (2x + 3)

That means that perhaps f(x) has one of these two factors.

(2x   3)(x   3)

You want the 2x and 3 to multiply. The middle term has to be -, so when 2x and 3 multiply likely it is 3 that gives you the minus answer.

(2x + 3)(x - 3) should be the way f(x) factors, and it is.

f(x) / g(x) =<u> (2x + 3) (x - 3)</u>

                 (2x + 3)(2x - 3)

2x + 3 cancels. The answer is

(f/g)x = (x - 3)/(2x - 3)

How many real solutions does the equation y=12x-9x+4 have?
jek_recluse [69]

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

                     y-(12*x^2-9*x+4)=0 

Step by step solution :<span>Step  1  :</span><span>Equation at the end of step  1  :</span><span> y - (((22•3x2) - 9x) + 4) = 0 </span><span>Step  2  :</span><span>Equation at the end of step  2  :</span><span> y - 12x2 + 9x - 4 = 0 </span><span>Step  3  :</span>Solving a Single Variable Equation :

<span> 3.1 </span>    Solve  <span> <span>y-12x2+9x-4</span> </span> = 0 

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
