The general equation of a line is expressed as:

y = mx + b

We have to write the equations to this form to see whether from there we can conclude something.

y = 3x – 7             (1)
6x – 2y = 12        (2)
-2y = 12 - 6x
y = 3x -6

We can see that both equations have the same slope and different values of y-intercept. Therefore, they are parallel and would never meet. 

The correct answer is option C, there is no solution.

Y = 3x - 7 . . . . . (1)
6x - 2y = 12 . . . (2)

Putting (1) into (2) gives
6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12

Therefore, there is no solution.

Which factor is important to consider when building a savings fund for planned,long term needs ?
netineya [11]

Answer:

Principal amount of investment.

Interest rate.

Simple or compound interest.

Time to hold the investment.

Step-by-step explanation:

There are several factors to consider when building a savings fund for planned long term needs.

First of all, we have to consider the amount of principal money we can invest in. It may be a one-time investment or a systematic investment plan. I case of a one-time investment we can easily calculate the investment amount but in case of monthly or yearly investment, we have to be sure that we will be able to invest the amount for the said period of time.

Second is the interest rate that the fund is giving i.e. APR of the fund. Again, take care to identify whether it is a simple interest or compound interest. Obviously the compound interest is better than simple interest as it gives more interest.

The third is the time for which you can hold the money without withdrawal. (Answer)

14. A wheel turns through 90 revolutions per minute.
Mazyrski [523]

1 revolution = 360 degrees

360 degrees x 90 revolutions per minute = 32,400 degrees per minute.

1 minute = 60 seconds.

32,400 degrees per minute / 60 seconds = 540 degrees per second.

Let's solve your equation step-by-step.
AleksAgata [21]
3 - (5x + 4/5) = x/2
3 - 5x - 4/5 = x/2
3 - 4/5 = x/2 + 5x
15/5 - 4/5 = x/2 + 5x
11/5 = x/2 + 5x.....multiply both sides by 10
22 = 5x + 50x
22 = 55x
22/55 = x
2/5 = x
