8x² - 2x - 1 = 0
8x² - 4x + 2x - 1 = 0
4x (2x - 1) + 1 (2x - 1) = 0
(4x + 1)(2x - 1) = 0
4x + 1 = 0 or 2x - 1 = 0
x = -1/4 0r x = 1/2
The process of finding which prime numbers you need to multiply together to get a certain number. ex: 21=7x3 20=2x2x5
Answer:
Option A, Left by 4 units
Step-by-step explanation:
<u>Step 1: Convert g(x) to a function square</u>
We currently have g(x) in this order: 
However, we want g(x) to be in this order: 
The first thing we have to do is to factor it out:



<u>Step 2: Now we can see which way we need to move it</u>
The original form is: 
Since the - has changed to a +, that means that we moved -4 spaces down the x-axis. This means that we move left by 4 units.
Answer: Option A, Left by 4 units

Answer:
v = 85/t
Step-by-step explanation:
Velocity is the change in displacement of a body with respect to time. It is expressed as
velocity = displacement/time
v = d/t
Given
d = 85km
t = t
Substitute tis parameters into the function;
v = 85/t
Hence the velocity v as a function of travel time t in hours is expressed as;
v = 85/t
