For this, there is two rules. The common slope-intercept form is y=ax + b. For parallel, b can change, but a, or the slope, can't change. But for perpendicular, the a should be -1/a, where the answer for times the original equation, or a, and the second equation, or -1/a, is -1. To prove these two rules, you can graph it using random numbers but follow these two rules. if you have any part that don't understand for this answer, feel free to ask in the "Ask for details" section.
Answer:
A, C, and D
Step-by-step explanation:
Answer:
Average score per game = 60,000 per game
Step-by-step explanation:
Given:
Points scored in first game = 25,000
Points scored in second game = 125,000
Points scored in third game = 30,000
Find:
Average score per game
Computation:
Average = Sum of observation / Number of observation
So,
Sum of all game = 25,000 + 125,000 + 30,000
Sum of all game = 180,000
Number of games = 3
Average score per game = 180,000 / 3
Average score per game = 60,000 per game
Answer:15
Step-by-step explanation:
X = 19. 19-4 = 15
A²-b²=(a-b)(a+b)
so if (x+8) is a factor then (x-8) is also a factor
so
(x+8)(x-8)=x²-8²=x²-64
the blank is 64
