Answer:

-1/2

Step-by-step explanation:

Rearranging this equation to slope-intercept form, we see the slope (x-coefficient) is 2:

2x = 7 + y . . . . . add y

y = 2x -7 . . . . . . subtract 7

The slope of the perpendicular line is the opposite of the reciprocal of this:

-1/2 = slope of perpendicular

The complete factorization of -12x^3 + 14x^2 +6x is -2x(ax + 1)(2x-3). What is the value of a?

tester [92]

Answer:

a = 3

Step-by-step explanation:

-12x³+14x²+6x = -2x(ax+1)(2x-3)

Divide both sides by -2x(2x-3)

$\frac{-2x(ax+1)(2x-3)}{-2x(2x-3)} = - \frac{12x^{3} }{-2x(2x-3)} + \frac{14x^{2} }{-2x(2x-3)} +\frac{6x}{-2x(2x-3)}$

ax+1=3x+1

Subtract 1 from both sides

ax=3x

Divide both sides by x

a=3

What is the solution to the system of equations below? y = negative one-fourth x + 2 and 3 y = negative three-fourths x minus 6

Arlecino [84]

Answer:

no solution

Step-by-step explanation:

Suppose the system equations are:

y = (-1/4)x + 2 (1)

3y = (-3/4)x – 6 (2)

If we multiply equation (1) by 3:

3y = (-3/4)x + 6 (1)

3y = (-3/4)x – 6 (2)

then subtract it from equation (2):

0y = 0x – 12

0 = -12

This is not possible, therefore, the system equation has no solution
