2 x ( 4(3) - 1) = 22
It is: 6*(2+3-1)+80 = 25
The solution pair is (-7, 22), demonstrated as follows: (1) x + y = 15 : given; (2)4x + 3y = 38 : given; (3)3x + 3y = 45 : equation (1), multiplied by 3; (4) x = -7 : equation (2), minus equation (3); (5) y = 22 : equation (1), minus equation (4).

No. The factors of 22 are 1, 2, 11, and 22.
(4 x 3 - 1) x 2 = 22
2 x ( 4(3) - 1) = 22
If 2x = 22 Then x = Log2 22
The vertex of a parabola is found by using the solution of the equation -b/2a and putting it into the quadratic equation. a is the coefficient of x^2. b is the coefficient of the other x in the equation. Ex. y=2x^2+2x+1 -b/2a = -2/2(2) = -1/2 Now put -1/2 in the place of every x in the equation. y=2(-1/2)^2+2(-1/2)+1 The vertex is (-1/2, 1/2)
It is: 6*(2+3-1)+80 = 25

-3+(-5)2=22
2*(4*3 - 1)
The differences between the values are 2, 4, 6, 8 The differences between these differences are 2, 2, 2 Thus the pattern's equation starts n2 The pattern minus n2 is 1, 0, -1, -2, -3 The difference between these values is -1 Thus the equation continues n2-n+2 This equation gives us 2, 4, 8, 14, 22, 32, 44, 58, 74...
