Use the solution method to the system of equations 8x+5y=9 , y=x+7

Step-by-step explanation:

Given Equations:

  Equation:1

      Equation:2

Using substitution method:

Put the value of 'y' in Equation:1

Adding the like terms:

Subtracting '35' both sides:

Dividing '13' both sides:

Put the value of 'x' in Equation:2

The solution of the equation is:

x = -2

y = 5

Step-by-step explanation:

8x+5y=9 (i)

y=x+7 (ii)

Substitute (y = x + 7) in equation (I)

8x + 5(x + 7) = 9

8x + 5x + 35 = 9

13x + 35 = 9

13x = 9 - 35

13x = -26

Divide both sides by 13 to make x the subject :

x = -26 / 13

x = -2

Substitute x = -2 in equation (ii)

y = x + 7

y = -2 + 7

y = 5.

TO CHECK:

x = -2

y = 5

8x+5y=9

8(-2) + 5(5) =

-16 + 25 = 9.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

7 is the median   7.875 is the mean
