Step-by-step explanation:
<u>Step 1: Define</u>
x³ + 3x² = x + 3
x = -1
<u>Step 2: Check</u>
- Substitute in <em>x</em>: (-1)³ + 3(-1)² = -1 + 3
- Evaluate exponents: -1 + 3(1) = -1 + 3
- Multiply: -1 + 3 = -1 + 3
- Add: 2 = 2
Answer:
A) 52 units
Step-by-step explanation:
The length of a line joining 2 points on a number line is given by the difference between the co-ordinates of the 2 points.
Therefore PQ= 
Hence the length of the line is 52 units

It would be difficult to help you.
It's all one big mess.
Was it supposed to be two or three separate expressions?
Answer:
The correct answer is the third option
Step-by-step explanation:
Have different slope but have the same y-intercept, so they have no solution.
y = 1/2x - 3
To graph this, the slope 1/2 which means go up once and to the right twice and b = -3, which means the y-intercept.
second equation:
y = -1/2x -3
To graph this, the slope -1/2 which means go down once and to the right twice and b = -3, which means the y-intercept.
