(4x - 1)(3x + 5)
12x^2 + 20x - 3x -5
12x^2 + 17x -5
The answer is C.

Answer:
$4.50
Step-by-step explanation:
We can use the distributive property to solve this problem. 0.05(50+40) is the total sales tax. 0.05 being the percentage and 50 and 40 being the things we need to distribute 0.05 to. This becomes 2.5+2. This is 4.5.
Part A: The slope of the linear function, f(x), equals 8, while the slope of g(x) = 3x - 2 equals 3.
--- Steps ---
Linear Function:
y2 - y1 -1 + 9
---------- = ---------- = 8
x2 - x2 0 + 1
g(x) = 3x - 2
Slope Intercept Form ~ y=mx+b
m is the slope, so in this equation, the slope is 3.
Part B: The function g(x) = 3x - 2 has a greater y intercept.
How to find the y intercepts:
g(x) = 3x - 2
The y intercept here is 2 because in slope intercept form, m is the slope and b is the y intercept: y =mx+b
F(x) table of values:
The y intercept here is -1. I found my answer by plotting all of the points on a coordinate grid. When you plot (0, -1), you will see that there is a spot where the line hits the y axis. That point is called the y intercept. So your y - value is -1, making the y intercept -1 also.
I hope this helps you out.
Combine like terms
Reorder the terms.
10x - 12y (+12y) + 8
-12y + 12y = 0
10x + 8 is your answer (as 8 does not have an x)
hope this helps
