Answer:
Problem #1: Option D, Line 4
Problem #2
PART A: Option 1, 2xy(2x−y)(2x+y)(4x2+y2)
PART B: Option 3, greatest common factor, Option 6, repeated difference of squares
Step-by-step explanation:
Problem #1
Step 1: Factor P(x) = 8x^3 + 20x^2 − 18x − 45
4x^2(2x + 5) - 9(2x + 5)
(4x^2 - 9)(2x + 5)
<em>(2x + 3)(2x - 3)(2x + 5)</em>
<em />
Answer: Option D, Line 4
Problem #2
<u>Part A: Factor</u>
2xy(16x^4 - y^4)
2xy(4x^2 + y^2)(2x + y)(2x - y)
Answer: Option 1, 2xy(2x−y)(2x+y)(4x2+y2)
Part B: Find the methods
Option 3, greatest common factor
Option 6, repeated difference of squares
Answer:
y = -1/6x -8
Step-by-step explanation:
The slope-intercept form of the equation for a line can be found by solving for y. The slope-intercept form is ...
y = mx + b . . . . . . line with slope m and y-intercept b
__
3x +18y = -144
18y = -3x -144 . . . . . subtract 3x
y = -3/18x -144/18 . . . . divide by 18
y = -1/6x -8 . . . . . . . simplify
Answer:
(-7, -8)
Step-by-step explanation:
To start we have to isolate a variable to get an equation for it.
Let's get an equation for x from the first equation:
x - 2y = 9
x = 2y + 9
Now that we know what x is in terms of y, lets plug it into our second equation:
3(2y + 9) - 5y = 19
6y + 27 - 5y = 19
y + 27 = 19
y = -8
Now that we know what y equals, let's plug it into our first equation and solve for x:
x - 2(-8) = 9
x + 16 = 9
x = -7
Now that we have x and y, we make our ordered pair, in terms of (x, y):
(-7, -8)

Answer:
6 * 5 * 4 * 3 * 2 * 1, i.e. 6! or 720. Of course, since both sets have the same number of elements, you can't have one-to-one without being onto, aka a surjection, so “one to one correspondence” is the right term (or bijection—merci, M.
