Study Notes
Equations and Operations
- To solve for x in 2x + 5 = 11, subtract 5 from both sides and then divide by 2, giving x = 3.
- Multiplying $2^3$ by $2^2$ results in $2^5$, or 32.
- The slope of a line passing through points (2,3) and (4,5) can be found using the formula (y2 - y1) / (x2 - x1), giving a slope of 2/2, or 1.
- Solving for y in y - 2 = 7 involves adding 2 to both sides, giving y = 9.
- Dividing $10^2$ by $10^3$ is equivalent to dividing 100 by 1000, giving 0.1.
- Solving for x in x - 3 = 7 involves adding 3 to both sides, giving x = 10.
- Raising 2 to the power of 5 results in $2^5$, or 32.
- Subtracting 5 from 11 results in 6.
- Dividing 12 by 3 results in 4.
- Adding 2 and 8 results in 10.
