A.4x=3y+6 we found the x that x=+3/4+3/2
Then we substitute x=+3/4+3/2 to the second equation (7x+3y=27)and we do the calculations to find y
7(3/4+3/2)+3y=27
21/4y+21/2+3y=27
21y+42+12y=108
33y=66
Y=2
We substitute y (2) to the first equation 4x-3y=6 to find x
4x -3(2)=6
4x=12
X=3

39= 3m - 12<br><br> I'd really appreciate it if you showed your work.
expeople1 [14]

To solve for m;

39 = 3m -12

39+12 = 3m -12 + 12 (add 12 to both sides)

51 = 3m

51 ÷ 3 = m

17 =m

m =17

Hope that helps, let me know if you don't understand something :D

Y= 4x + 2<br> where the domain is the set of all of<br> the positive even numbers<br> less than 10.
inysia [295]

The range of the function y = 4x + 2 where the  domain is the set of all of

the positive even numbers  less than 10 is {10, 18, 26, 34}

The given equation is:

y  =  4x  +  2

The domain is the set of all of  the positive even numbers  less than 10.

That is, x = {2, 4, 6 ,8}

To get the range, find the values of y for x = 2, 4, 6, and 8

For x = 2:

y = 4(2)  +  2

y  =  8  +  2

y   =  10

For x = 4:

y = 4(4)  +  2

y  =  16  +  2

y   =  18

For x = 6:

y = 4(6)  +  2

y  =  24  +  2

y   =  26

For x = 8:

y = 4(8)  +  2

y  =  32  +  2

y   =  34

Therefore, the range = {10, 18, 26, 34}

Mean = £1.8 million


Step-by-step explanation:

The MEAN is the sum of all the numbers divided by the number of numbers.

  • <u>There are 5 numbers in total</u>
  • <u>The sum is 1.4+1.6+1.8+2.5+1.7=9 million</u>

Hence the mean is \frac{9}{5}=1.8 million
