Answer:

C(d) = d(2.25) + m(0.3)

Step-by-step explanation:

A taxi company charges $2.25 per ride plus $0.30 per mile.

Let d represent number of rides..

Let m represent number of Miles...

Then let C represent the total cost for each ride at a specific number of Miles.

The linear model representing the cost as a function of d the total ride

C(d) = d(2.25) + m(0.3)

The values stand independently because the customer can choose a different right and a different mile.

What are the zeros of the function f (x) = (x-6)(2x+10)
bazaltina [42]

Let f(x)=0.

(x-6)(2x+10)=0

Using the zero-factor property, equate each factor to 0 and then solve for x.

\begin{gathered} x-6=0 \\ x=6 \\  \\ 2x+10=0 \\ 2x=-10 \\ x=-\frac{10}{2} \\ x=-5 \end{gathered}

Thus, the zeros of the given function are 6 and -5.

The zeros are the x-coordinate where the graph touches the x-axis.

Thus, the x-coordinates of where the graph touches the x-axis are -5, and 6.

What is the slope of a line that is parallel to the line shown on the graph
sertanlavr [38]
Here: m = 6, b = 4.
m is the slope of the line, so slope is 6.
any line parallel to this line will also have the slope of 6.
any line perpendicular to the given line will have the slope of: -1/m1<span>.

hope this helps leave a thanks if it does </span>

A rectangle is 9 ft long and 40 in. wide. What is its perimeter in inches?
quester [9]

Answer:

296 inches

Step-by-step explanation:

The perimeter is the sum of sides of a rectangle

As the length is in feet while the width is in inches, a unit conversion must take place

As 1  feet  equals to 12 inches

9 feet would be equal to 12*9=108 inches

The perimeter of a rectangle= 2(width)(length)

= 2(108)(40)

=296 inches

Simplify the expression -4x2(3x − 7).
11111nata11111 [884]
-4*2(3x-7)
-8(3x-7)
8 times 4 is 24 so it would be negative 24 
so 3 times 16.3=48.9 then you add 7 which rounds it off it 56  
so x is 16.3 thats how you get this expession
