Oh. It's rounding. So, for example, depending what you were told to round to, the second problem would be 760-330=430
It’s the first answer choice

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
y = -23(x + 9) + 4
y = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in <em>y</em>: 0 = -23(x + 9) + 4
- [Subtraction Property of Equality] Subtract 4 on both sides: -4 = -23(x + 9)
- [Division Property of Equality] Divide -23 on both sides: 4/23 = x + 9
- [Subtraction Property of Equality] Subtract 9 on both sides: -203/23 = x
- Rewrite: x = -203/23
The answer would be B. If you want to FIND how many points a person has, you put the "p" on its own on the left of the equation, and since every field goal (f) you score is worth 3 points, just multiply "f" by 3 (3f).
For example, if someone scored 5 field goals in a game, to find how many points they totalled, just plug in the 5 for "f":
1. Get equation:
p = 3f
2. Plug in field goals for "f":
p = 3(5)
3. Solve:
p = 15
