Step-by-step explanation:
<u>Step 1: Define</u>
2(n + 3) - 4 < 6
<u>Step 2: Solve for </u><em><u>n</u></em>
- [Addition Property of Equality] Add 4 on both sides: 2(n + 3) < 10
- [Division Property of Equality] Divide 2 on both sides: n + 3 < 5
- [Subtraction Property of Equality] Subtract 3 on both sides: n < 2
Here we see that any value <em>n</em> smaller than 2 would work as a solution to the inequality.
Answer:
Well if we were to graph this quadratic equation. We would be looking for places on that graph where Y is equal to zero. Well those are places where the graph crosses the x axis.
Step-by-step explanation:
Answer:
x = 4 or x = -3
Step-by-step explanation:
Take square both the sides,
x² - x - 12 = 0
x² - 4x + 3x - 3*4 =0
x*(x - 4) + 3*(x - 4)= 0
(x- 4 )(x+3) =0
x -4 =0 or x + 3 = 0
x = 4 or x = -3
Answer:
Step-by-step explanation: 250 miles + 50 miles = 300 miles
