Pulling out like terms
9.1 Pull out like factors :
-3x6 + 9x5 - 2x4 - 24x3 + 20x2 + 16x - 16 =
-1 • (3x6 - 9x5 + 2x4 + 24x3 - 20x2 - 16x + 16)
Checking for a perfect cube :
9.2 3x3 - 3x2 - 4x + 4 is not a perfect cube
Trying to factor by pulling out :
9.3 Factoring: 3x3 - 3x2 - 4x + 4
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -4x + 4
Group 2: 3x3 - 3x2
Pull out from each group separately :
Group 1: (x - 1) • (-4)
Group 2: (x - 1) • (3x2)
---------------------
---------------
Add up the two groups :
(x - 1) • (3x2 - 4)
Step-by-step explanation:
Substitute 2x + 14 for y in -4x - y = 4:
-4x - (2x + 14) = 4
-4x - 2x - 14 = 4
-6x - 14 = 4
-6x = 18
x = -3
Substitute -3 for x in y = 2x + 14 and -4x - y = 4:
y = 2(-3) + 14 --> y = -6 + 14 --> y = 8
-4(-3) - y = 4 --> 12 - y = 4 --> -y = -8 --> y = 8
So y = 8
Slope is a number that represents how much the y-value changes over a certain span of x-values. However, since y is a constant set to 3, the y-value never changes, meaning the slope is 0.
The slope will always be 0 for any equation that has the form:
You could also choose two random points and solve for the slope. Let's take (0,3) and (1,3).
You can verify these are actual points on the line since the y-value is 3.
Now, let's calculate for slope:
The slope is indeed 0 as shown from this.

Answer:
C
Step-by-step explanation:
Because i'm smart and did the math.
You could change all fractions to decimals
2 5/8 = 2.625
3/4 = 0.75
2.625 - 0.75 = 1.875
If you need to stay in fractions, you could do it this way.
2 5/8 = 21/8
3/4 = 6/8
21/8 - 6/8 = 15/8 = 1 7/8 Her classmates ate 1 7/8 pounds of nuts
