Answer:The answer can be calculated by doing the following steps;
Step-by-step explanation:
I think you have done some mistakes in question because at one stage there comes a complex no. And at the end the value of n comes in decimal.
Answer:
7 Hours 12 Minutes
Step-by-step explanation:
So they one of the printer increases at a rate of 1/12 and the other increases at a rate of 1/18. Since you don't know the time it actually takes, you will replace both numerators with and x. (x/12 and x/18). You want to set these up so that they are adding. (x/12 + x/18=1). Since you're adding, you want to change it to the same denominator. The lowest is 36 so you multiply x/12 by 3/3 (so you don't unbalance the equation) and x/18 by 2/2. You'll end up with 3x/36 + 2x/36= 1 which will simplify to 5x/36=1. Multiply each side by 36 to leave the variable by itself. It becomes 5x=36 and when you divide it by 5 you get 7.2. So it's seven and .2 hours, which is equivalent to7 and 1/5 of an hour or 7 hours and 12 minutes.
Answer: B.no
Step-by-step explanation:
To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer
Answer:
8, 2, - 9, - 7
Step-by-step explanation:
The domain is the first coordinate of an ordered pair. This means that the domain is going to be x. In this set of ordered pairs, the domain is 8, 5, - 9, - 7.

Answer:
3x = 1.5x + 8.4
8.4/1.5=5.6
5.6 x 3 = 16.8
5.6 x 1.5 + 8.4 = 16.8
Step 1. Cancel out the -0.4 so you add 0.4 to both sides
Step 2. Divide 8.4 by 1.5 = 5.6
Step 3. Replace X with 5.6 and check if the equation is correct
5.6 is the answer
