Answer:
- 1
Step-by-step explanation:
f(x) + g(x) = - 2x² + 1 + 3x = - 2x² + 3x + 1
Substitute x = 2 into the expression for f(x) + g(x)
= - 2(2)² + 3(2) + 1 = - 8 + 6 + 1 = - 1
The expression log₆(3/50) = x and the similar expression cannot be solved without a calculator or logarithm table
<h3>How to solve logarithm without calculator?</h3>
There are three ways to solve a logarithm expression
- Using calculator
- Using the logarithm table
- Logarithm rules
If a logarithmic expression cannot be solved by logarithm rules, then one has to apply a calculator or logarithm table to solve such expression
The above means that the expression log₆(3/50) = x and the likes cannot be solved without a calculator or logarithm table

Answer:
The first one is 2, the second one is 7/8.
Step-by-step explanation:
You can do self-checking.
Answer:
9
Step-by-step explanation:
1. You would make these to equations equal to each other because there are parellel(they have the same angel)
2. EQUAL these 2 equations together to find r.
3. SOLVING for r
7r - 5 = 6r + 4
r = 9
