The cost of parts on your automobile repair bill was $149. The cost for labor was $25Per hour. Write a linear equation giving the total cost C, in terms of t, the number of
Hours. C(t)

Answers

Answer:

C=149+25t

Step-by-step explanation:

Since the total cost is C you would set it all equal to C.

Then the one time cost for parts was 149 so you have to add that in.

And $25 per hour would be multiplied by t because t is the number of hours.

Being technologically literate requires being able to ______. a. Write simple programs in Flash b. Select the appropriate technology for a task c. Change the BIOS settings of a motherboard d. All of the above

Answers

Being technologically literate requires being able to B. select the appropriate technology for a task. You should know that if you want to write something on your computer, that you should open Word or some other program in which you can write, for example. Being technologically literate has nothing to do with programming because most people today don't know how to write programs or change the BIOS settings, because these aren't things that make people literate when it comes to technology.

If p(x) = x +9, and q(x) = 2x² + 3x, find p(2a) - q(a)

Answers

Answer:

p(2a) - q(a) = -2a² + 2a + 9

Step-by-step explanation:

Given;

p(x) = x + 9 and q(x) = 2x² + 3x,

we can replace 2a and a for p(x) and q(x).

p(2a) = 2a + 9 and q(a) = 2a² + 3a are the substituted values.

Now we can evaluate p(2a) - q(a):

p(2a) - q(a) = (2a + 9) - (2a² + 3a)

= 2a + 9 - 2a² - 3a

= -2a² + 2a + 9

p(2a) - q(a) = -2a² + 2a + 9

Hope this helps!
