Hey there! :)

Answer:

y = 11.

Step-by-step explanation:

Set both of the equations equal:

5x - 9 = x² - 3x + 7

Rearrange the equation:

0 = x² - 3x - 5x  + 9  + 7

Combine like terms:

0 = x² - 8x + 16

Factor:

0 = (x -4)²

Solve for x:

0 = x - 4

x = 4.

Plug this into an equation to solve for 'y':

y = 5(4) - 9

y = 20 - 9

y = 11.

Answer:

Step-by-step explanation: Is this what you needed ?

I Hope i am right

x^2-3x+7\\y =x^2-3x+7\\x =  -b / 2a\\x = -(-3)/2(1)\\x = 3/2\\y=(3/2)^2-3(3/2) +7\\y=9/4 -9/2 +7\\y = -9/4+7\\y =19/4

Sustitute -y=5x-9-into\\y=x^2-3x+7\\(5x-9)^2=x^2-3x+7\\Solve-for-x \\x =4\\substitute-4-for - -in ; y=5x-9\\y = 5(4)-9\\y = 20-9\\y =11

➷ To find the median, you need to order your numbers first.

14, 16, 18, 21, 34, 60

There is an even amount of numbers, so you find the mean of the middle two numbers.

18+21=39/2=19.5

Median=19.5
