Using the equation y = 7x^2 + 9, we can substitute x = 5 into the equation to find the missing value of y:
y = 7(5)^2 + 9
y = 7(25) + 9
y = 175 + 9
y = 184
Therefore, the missing value to make the point (5, 184) on the equation y = 7x^2 + 9.
y = 7x^2 + 9.
y = ___
y = 7(5)^2 + 9
y = 7(25) + 9
y = 175 + 9
y = 184
Therefore, the missing value to make the point (5, 184) on the equation y = 7x^2 + 9.

y = -9(16) + 4
y = -144 + 4
y = -140
Therefore, the missing value to make the point (4, -140) on the equation y = -9x^2 + 4.

26 = 5x - 6
Add 6 to both sides:
26 + 6 = 5x
32 = 5x
Divide by 5:
x = 32 / 5
x = 6.4
Therefore, the missing value to make the point (6.4, 26) on the equation y = 5x - 6.
Given the equation y = 5x - 6 and point (x, 26), we substitute y = 26 into the equation and solve for x:
26 = 5x - 6
Add 6 to both sides:
26 + 6 = 5x
32 = 5x
Divide by 5:
x = 32 / 5
x = 6.4
After reevaluating the calculation, I can confirm that the missing value to make the point (6.4, 26) on the equation y = 5x - 6 is correct.
