Answer: 3ab + 5b-6 when a=-1 and b=3 ?

Step-by-step explanation:

1st you have to write it out.

3*1*3+5*3-6

Then you need to separate them into 2 different problems

3*1*3=9

5*3-6=9

Lastly, you need to add them both together.

9+9=18

Answer:

3 * -1 x 3   +  5 * 3 - 6 = 0

Step-by-step explanation:

Replace (a)s and (b)s with the given numbers

so (a)s becoming -1 and (b)s becoming 3.

this leads up to the given expression:

3 * -1 x 3   +  5 * 3 - 6

3 times -1 = -3 multiplied by that 3 is -9

since a negative multiplied by a positive is a negative.

With that you have -9 +  5  x 3 - 6

take 5 and 3, multiply them to get 15 and subtract 6.

this ends up with '9'

Lastly ending up with -9+9 = 0

4. A video club costs $20 to join. Each video that is rented costs $2.25. Let v represent the number of videos.
shepuryov [24]

Answer:

B.

Step-by-step explanation:

$2.25 is the cost of each video that is rented, so $2.25 times v (or 2.25v) represents the cost of 'v' videos.

$20 is the constant, as it costs $20 to join the club. Since this doesn't change, it is the constant.

So, we would have the equation:

f(v) = 2.25v + 20

f(v) is the total cost.

B is your answer because it is the only one with the correct equation.

Hope this helps!
