The x is a placeholder for a number. Think of x like a box and inside the box will go a number. In this case, -4 will replace x
7 - 2x = 7 - 2(-4) = 7 + 8 = 15
<h3>Answer: 15</h3>
Answer:
185/9
Step-by-step explanation:
From -∞ to -4 the blue line is above the X axis which means it is >0
The blue line is negative between -4 and -3
This would make the correct answer: F(x) > 0 over the interval (-∞,-4)
You would just do 1÷5 so it would equal 20 or 20%.
