The least common denominator  : LCD

(x + 1) / 4x    and   (3(x + 1)) / 2x^2

factor  4x  :   2, 2, x

factor  2x^2 :   2, x, x^2

take highest powers  2^2 and x^2

LCD is   4*x^2

What is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4,-6)
LUCKY_DIMON [66]

Answer:

y + 6 = -2 (x-4)

Step-by-step explanation:

Point-slope formula is represented by the equation y-y_1 = m (x-x_1). When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the m, x_1, and y_1 for real values.

The m represents the slope of the line. Since we know the slope is -2, substitute -2 for m. The x_1 and y_1 represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for x_1 and -6 for y_1. This gives the following answer and equation:

y-(-6) = -2 (x - (4))\\y + 6 = -2 (x-4)

Donte is driving 838 miles to his aunt’s house. His car has a 14-gallon tank and goes 26 miles for every gallon of gasoline. Don
ipn [44]
So you first do 26 x 14 = 364 miles for 14 gallons
838 ÷ 364 = 2.302
You then have to round the number, and because you can't stop 0.302 times, the answer is 3.

A rectangle table is two times as long as it is wide. If the area is 50ft^2. Find the length and width of the table.
const2013 [10]

Answer:

Width = 5

Length = 2*5 = 10

Step-by-step explanation:

Givens

Let the width = W  = x

Let the length = L =  2x

Equation

Area = L * W

Solution

Area = 2W * W                  Substitute into the given equation

Area = 2W^2                     Simplify the right

50    = 2W^2                     Divide by 2

50/2 = 2W^2 / 2                Simplify

25 = W^2                           Switch

W^2 = 25                           Take the square root of both sides

sqrt(w^2) = sqrt(25)

Answers

w = 5 ft

L = 2 * 5 = 10 ft
