y equals 2

(y - 7)(y - 2)

6x - 4y

Point slope equation: Y=3X+12

that's impossible

a square

-6

when you multiply two minus numbers the minus signs cancel each other out so -12 * -6 = 72

Incomplete information. Cannot be answered.

If the question is what number times 8 = 34 the answer would be 4.25

(-4,3)

(3, -4)

I do not understand this question, so these are a few possible equations that you might mean:

10x8x12=80

(10x8x1)2=160

(10x8x1)2=6400

1/2*(142-42) = 77 diagonals

3 x 28 = 84

2x2+5x-3 = 0

(2x-1)(x+3) = 0

x = 1/2 or x -3

Take f(x) = cos(3x)

∫ f(x) dx

= ∫ cos(3x) dx

Take u=3x → du = 3dx

= ∫ 1/3*cos(u) du

= 1/3*∫ cos(u) du

= 1/3*sin(u) + C, C ∈ ℝ

= 1/3*sin(3x) + C

Two quarts is a half gallon. It is also four pints or 64 fluid ounces.

Presumably this is a simultaneous equation question which can be solved using the elimination method?

4(x+2y = -1)

4x+3y = -9

First multiply all terms in the top equation by 4:

4x+8y = -4

4x+3y = -9

Subtract the bottom equation from the top equation in order to eliminate x remembering that a - - is equal to a + So -4 - -9 is equal to 5:

5y = 5 => y = 1

Substitute the value of y into the original equations to find the value of x:

Therefore: x = -3 and y = 1

x4 + 3x3 - x2 - 9x - 6 = 0

x4 + x3 + 2x3 + 2x2 - 3x2 - 3x - 6x - 6 = 0

x3(x + 1) + 2x2(x + 1) - 3x(x + 1) - 6(x + 1) = 0

(x + 1)(x3 + 2x2 - 3x - 6) = 0

(x + 1)[x2(x + 2) - 3(x + 2)] = 0

(x + 1)(x + 2)(x2 - 3) = 0

So x + 1 = 0 so that x = -1

or x + 2 = 0 so that x = -2

or x2 - 3 = 0 so that x = +/- sqrt(3)

x=7
