Answer:
A graphing calculator is more accurate than graphing by hand. If the slope and/or y-intercept is a fraction or decimal, it is more difficult to accurately graph by hand.
Step-by-step explanation:
A) 3x+4=21
3x=21-4
3x=17
x=17÷3
x= 5.7
The answer is p = 5.
Here are the steps I did.
1. Simplify 8p + 10p - p - 8p + 5 to 9p + 5 ( 9p + 5 = 50)
2. Subtract 5 from both sides ( 9p = 50 - 5)
3. Simplify 50 - 5 to 45 ( 9p = 45)
4. Divide both sides by 9 ( 45/9)
5. Simplify 45/9 to 5 ( p = 5)
