The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28. A table with 6 columns and 2 rows. T

he first column, Original System has 2 x minus 2 y equals 6 and 4 x plus 4 y equals 28. The second column, Equivalent System, has 4 x minus 4 y equals 12 and 4 x plus 4 y equals 28. The third column, Sum of equations in Equivalent System, has 8 x equals 40. The fourth column, Solution to System, is blank. The fifth column, New System Using Sum, has 4 x plus 4 y equals 28 and 8 x equals 40. The sixth column, Solution to New System is blank. Which solution can be used to fill in both blanks in the table? (2, 5) (5, 2) (5, −8) (−8, 5)

The solution is (5,2)

Step-by-step explanation:

From the third column the equation for sum of equivalent system is given as;

8x = 40

divide both sides by 8 to get value of x

8x/8 = 40/8

x=5

Using the value of x in the fifth column's first equation will be;

4x +4y =28

4(5) + 4y =28

20 +4y =28

4y= 28-20

4y=8

divide both sides by 4 to get y

4y/4 =8/4

y=2

The solution is x=5 and y=2 written as (5,2)

What is the vertex of this equation?
AfilCa [17]

Answer:

  (5, 4)

Step-by-step explanation:

The equation can be written in vertex form by adding and subtracting 25:

  y = -(x^2 -10x +25) -21 +25

  y = -(x -5)^2 +4

Then the vertex can be identified as (5, 4).
