Answer:
Addition property of equality.
Step-by-step explanation:
You are adding something to both sides of the equation.
Answer:
A: The expression is a trinomial with a degree of 4.
Step-by-step explanation:
The expression has three parts, so it's a tronomial.
The largest exponent is 4, so it has a degree of 4.
Answer:
A. Corresponding angle theorem
Step-by-step explanation: I just took the test on edg
Answer:
15x + 180 ≥ 900
x ≥ 48
Step-by-step explanation:
x = amount of laptops needed to sell.
Equation:
15x + 180 ≥ 900
15x ≥ 720
x ≥ 48
Check:
15(48) + 180 = 900
720 + 180 = 900
900 = 900 (It's good, she needs to make at least 900, so she needs to sell at least 48 laptops).
1. tan(x) . . . . 3rd choice
2. False . . . it is a graph of sin(x)-3
3. Of the choices offered, the best is sin(x +45°), the 2nd selection. It actually looks like a graph of sin(x +60°).
4. True . . . . it matches the graph of Question 1 shifted up 2 units
5. Probably True. The graph is of the given equation. The wording of the question leaves doubt. (It is a "graph", not an "equation." If the question is taken literally, the answer is False.)
6. 2cos(x) . . . . . the 4th choice
