# Dividing fractions that contain exponents? (answer)

That fact that there are only 2 term in 27n2-147 may suggest it is a perfect square. And after dividing by 3 it is! 3(9n2-49). Factor each quadratic and cancel and you will find the answer.

Solve by factoring:  = (2k - 1)(k + 4) = 2k2 + -k +8k -4 = 2k2 +7k - 4

x + x + 2 + x = 144 3x + 2 = 144 3x = 142 x = 47 1/3

# 789 trillion written as a integer? (answer)

# Geometry problem involving triangles (answer)

Assuming the pole was perpendicular to the ground.  When the upper part fell it form a right triangle with the ground as one side. The ground between the two parts = 10 m Let the part remaining = X The part that fell = 17 - X 102 + X2 = (17 - X)2 100 + X2 =...

# FInding Per Hour: Solving (answer)

Let t = the time it takes for Nadine to catch up Distance Tyler goes in time t is D = 2 +2t Distance Nadine goes in time t is D = 6t Since the distance each goes is the same 6t = 2 + 2t 4t = 2 t = ½ hour

# f(x) = x^3 - 4x^2 + 9x - 36f(x) = x^3 - 4x^2 + 9x - 36 (answer)

If a polynomial function, written in descending order of the exponents, has integer coefficients, then any rational zero must be of the form +- p/q, where p is a factor of the constant term and q is a factor of the leading coefficient. The constant term is 36 The leading coefficient...

# sketch a graph of y=f(x) (answer)

This equation in it the slope intercept form. Y = mX + b where m is the slope and b is the y intercept. Put a point on the graph at the Y intercept (0, 5) The slope, m = (change in y) / (change in X) in this case 1/2 From the drqwn point move up 1 and right 2 and place a second...

# Use the slope-intercept form to state the equation of the line.m=-9;(0,1)is on the line (answer)

Since we are gine a point and the slope, start with the point slope form and slove for y to get the slope intercept form (Y - Y1) = m (X - X1) Y - 1 = -9 (X -0) Y - 1 = -9X Y = -9X + 1 This method can be used anytime you have a point and the slope to fine the slope intercept...

X-5 (Y-6Z)2 / X4Y-1Z-2  Using (Xn)m = Xnm = X-5 Y-12Z2 / X4Y-1Z-2 Using X-n = 1 / Xn  = Z4 / X9Y11

# how do you graph a -1/5 slope (answer)

slope = (change in y) / (change in x) In this case... the change in y = -1 the change in x = 5 for the y axis minus is down and plus is up for the x axis minus is left and plus is right so place one point anywhere on the graph and then go down 1 and right 5 and place a second point on...

# find an equation of the line containing the given pair of points (2,4) and (6,6) (answer)

Since you are given 2 points of a line, the Point Slope form of a line can be used to solve the problem. Y - Y1 = m (X - X1) , m = the slope and (X1,Y1) is one of the given points Use the 2 points to find the slope m = (change in Y) / (change in X)  = (6-4)/(6-2) = 2/4 =1/2 Y...

# In 1992, the moose population in a park was measured to be 4280 (answer)

Find the equation of the line: Since we have 2 points, we will use the point slope form. Points (1999, 6170) and (1992, 4280) slope m = change in y / change in x = (6170-4280) / (1999-1992) = 1890/7 = 270 Therefore the equation of the line is (Y - Y1) = m (X - X1) (Y...

# how to factor a trinomial (answer)

Example: 3X2 + 5X +3 (3X + 2) (X + 1) Sometimes the coefficient on the squared term can have more than one way to be factored. For example 8 can be 1*8 or 2*4 Consider 8X2 + 11X + 3 = (8X + 3)(X + 1) and 8X2 + 10X + 3 = (4X + 3)(2X...
