If it is (x-4)(x-2)3x than the answer is 3x(x^2-4x-2x+8) = 3x(x^2-6x+8) = 3x^3 - 18x^2 + 24x


If it is (x+4)(x-2)3x than the answer is 3x(x^2+4x+2x+8) = 3x(x^2+6x+8) = 3x^3 + 18x^2 + 24x

What is the equation of the graphed line written in
Andrew [12]

<u>Given</u>:

Given that the graph of the linear equation.

We need to determine the equation of the graph.

<u>Slope</u>:

The slope of the equation can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Let us substitute the coordinates (2,0) and (0,-4) in the above formula, we get;

m=\frac{-4-0}{0-2}

m=\frac{-4}{-2}

m=2

Thus, the slope of the equation is 2.

<u>y - intercept:</u>

The y - intercept of the equation is the value of y when x = 0.

Hence, from the graph, it is obvious that when x = 0, the value of y is -4.

Therefore, the value of the y - intercept is b = -4.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

y=mx+b

Substituting the values, we have;

y=2x-4

Subtracting both sides by 2x, we have;

-2x+y=-4

Dividing both sides by -1, we get;

2x-y=4

Thus, the equation of the line is 2x-y=4

Hence, Option B is the correct answer.

The sum of two numbers is 62 the smaller number is 6 less than the larer number what are the numbers
muminat
X= larger number
x-6= smaller number

x + (x - 6)= 62
combine like terms

2x - 6= 62
add 6 to both sides

2x= 68
divide both sides by 2

x= 34 larger number


SMALLER NUMBER
x - 6= 34 - 6= 28


ANSWER: The smaller number is 28 and the larger number is 34.

Hope this helps! :)
