A line passes through the point (4,-2) and has a slope of 1/2 what is the value of a if the point (-4,a) is also on the line

Slav-nsk [51]

Answer: The value of a is -6.

Step-by-step explanation:

To do this we need to find the y-intercept first.

-2= 4(1/2) + b

-2=2+ b

-2 -2

b= -4 so now the y-intercept is -4 so we will now have the equation y= 1/2x -4

so now put -4 into the equation for x and solve for y.

y= 1/2(-4) -4

y = -6

Factor completely. x 3 + 6x 2 - 4x - 24

Ulleksa [173]

You can factor (x^3 and 6x^2) and (-4x and -24).

So x^2(x+6) - 4(x+6)

(x^2-4)(x+6)

(x-2)(x+2)(x+6)

Help me with math please, quickly

Answer:

$3\neq -3$

False

Step-by-step explanation:

$y=3x-9\\\\x-\frac{1}{3}y=-3$

You substitute $y$ for the second equation.

$x-\frac{1}{3} y=-3\\\\x-\frac{1}{3}(3x-9)=-3$

Then you have to distribute $-\frac{1}{3}$ .

$x-x+3=-3$

Combine like terms.

$3\neq -3$
