19)  15/a = 3/2 

Start by cross multiplying....

3a = 30 

Divide both sides 3 

a = 10 

21)   2/7 = 4/d 

        2d = 28
       
        d= 14 

23)  8/p = 3/10

       
80 = 3p
         p = 26.66

25)  2 / -5 = 6/t
        2t = -30

      t = -15

Honestly I dont know how to do this just please help me
V125BC [204]
F(x) = 3x - 2
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
f(8) - f(-5) = 22 - (-17)
f(8) - f(-5) = 39
Hope this helped! Good luck! :)

What is the graph of y = x - 3 (shown below) translated up 2 units?
Mrac [35]
I don't see a "shown below," so I'm not sure if I could accurately answer your question. However, if your graph point is (x,-3), then it wants you to move your graphed point up two units. I believe that would be y = x -1? I'm not sure

The cost to purchase a song from iTunes is $0.99 per song. To purchase a song from Napster, you must be a member. The Napster me
vlada-n [284]

Answer:

It will take 100 songs for the monthly price of Napster to cost the same as iTunes.

Step-by-step explanation:

Let's create two equations to represent iTunes (T(d)) and Napster (N(d)):

T(d)=0.99d

N(d)=0.89d+10

In order for us to find when the two prices will be the same, let's set the equations equal to each other and solve for x:

0.99d=0.89d+10

0.1d=10

d=100

Find two consecutive integers whose sum is 67. Which of the following equations could be used to solve the problem?
Hunter-Best [27]
The desired answer is probably that
  2x + 1 = 67
is the equation that can be used to solve the problem. In this case, x represents the smallest integer.

_____
I like to work problems in consecutive integers by considering their average. Here, it is 67/2 = 33.5. The two consecutive integers whose average is 33.5 are 33 and 34, the solution to the problem. For this, the first equation applies, where x is the value halfway between the two integers. (This answer (2x=67) would likely get marked wrong by your computer grading system.)
