(x - 7)(y - 9)

= x*y - 7*y - 9*x + (-7)*(-9)

= xy - 7y - 9x + 63

= x*y - 7*y - 9*x + (-7)*(-9)

= xy - 7y - 9x + 63

x^3 + x^ 2 - 25x - 25

= x^2(x + 1) - 25(x + 1)

= (x + 1)(x^2 -25)

= (x + 1)(x + 5)(x - 5)

= x^2(x + 1) - 25(x + 1)

= (x + 1)(x^2 -25)

= (x + 1)(x + 5)(x - 5)

The vertex of the parabola whose equation is y = x^2 + 2x + 9 is (-1 , 8) .

x = -2/2 = -1

when x = - 1

y = (-1)^2 + 2*(-1) + 9

y = 1 - 2 + 9

y = 8

x = -2/2 = -1

when x = - 1

y = (-1)^2 + 2*(-1) + 9

y = 1 - 2 + 9

y = 8

Harry will be 18 years old in 6 years .

Let Nick now is y , Harry now is x

y = 7x

y + 6 = 5(x + 6)

we ger x = 12

y = 84

x + 6 = 12 + 6 = 18

So Harry is 18 in 6 years

Let Nick now is y , Harry now is x

y = 7x

y + 6 = 5(x + 6)

we ger x = 12

y = 84

x + 6 = 12 + 6 = 18

So Harry is 18 in 6 years

when x = 3,

5x + (-2x^2) = 5(3) - 2(3^2) = 15 - 18 = -3

5x + (-2x^2) = 5(3) - 2(3^2) = 15 - 18 = -3

2(4x + 5) > 7x + 20

8x + 10 > 7x + 20

8x - 7x > 20 - 10

x > 10

8x + 10 > 7x + 20

8x - 7x > 20 - 10

x > 10
