7 0

Answer:

x=1

Step-by-step explanation:

<em>First we have to isolate y</em>

Subtract 3x from both sides:

y=-3x+9

y=-4x+10

<u>Multiply the bottom by -1:</u>

y=-3x+9

-y=4x-10

<u>Combine the equations:</u>

x-1=0

<u>Add 1 to both sides:</u>

<em><u>x=1</u></em>

I hope this helps u pls give a brainliest and a thx ;)

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)

PLEASE ANSWER AND SHOW WORKING OUT FOR ME PLEASE.
Lelu [443]
7932 x 56 = 444192 and since it’s asking you to multiply by .56 and 793.2, just move the decimal over to the left three places in your answer since there’s three digits after the decimals in your factors. so you get 444.192

Find three consecutive even integers. Such that 7 times of first integer is 4 more than the sum of second and third integers
attashe74 [19]

Answer:

1st even integer = 2

2nd even integer = 4

3rd even integer  = 6

Step-by-step explanation:

Let the consecutive even integers be:

1st = 2(x)

2nd= 2(x +1) = 2x + 2

3rd = 2(x + 2) = 2x + 4

According to Given conditions:

7(2x) = 4 +  2x +2 + 2x + 4

By Simplifying:

14x = 10 + 4x

Subtracting 4x from both sides

14x - 4x = 10 + 4x -4x

10x = 10

Dividing both sides by 10 we get:

x = 1

Now putting value of x in supposed integers:

1st even integer = 2(1) = 2

2nd even integer = 2(1)+2 = 4

3rd even integer = 2(1) + 4 = 6

I hope it will help you!
