Answer from: rosyjesus297

x=3y+18

Geometric figure: Straight Line

Slope = 0.667/2.000 = 0.333

x-intercept = 18/1 = 18.00000

y-intercept = 18/-3 = 6/-1 = -6.00000

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

x-(3*y+18)=0

Step by step solution :

Step 1 :

Equation of a Straight Line

1.1 Solve x-3y-18 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-3y-18 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 6/-1 so this line "cuts" the y axis at y=-6.00000

y-intercept = 18/-3 = 6/-1 = -6.00000

Calculate the X-Intercept :

When y = 0 the value of x is 18/1 Our line therefore "cuts" the x axis at x=18.00000

x-intercept = 18/1 = 18.00000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -6.000 and for x=2.000, the value of y is -5.333. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.333 - (-6.000) = 0.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 0.667/2.000 = 0.333

Geometric figure: Straight Line

Slope = 0.667/2.000 = 0.333

x-intercept = 18/1 = 18.00000

y-intercept = 18/-3 = 6/-1 = -6.00000

hope this helped:)))

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
