Answer:
Standard form
Step-by-step explanation:
Find the intersection points of the two equationsÑ
1) y = - x^2 + 6x
2) 4y = 21- x => y = 21/4 - x/4
Intersection => y = y => - x^2 + 6x = 21/4 - x/4
=> x^2 - 6x - x/4 + 21/4 = 0
=> x^2 - 25x/4 + 21/4 = 0
x^2 - 6.25x + 5.25 = 0
Use the quadratic equation and you find x = 1 and x ≈ 5.25
The respective y values are: y = 5 and y ≈ 3.94
=> points (1,5) and (5.25,3.94)
Answer: option b. (1,5) and (5.25,3.94)
Answer:
x = 66.74715005725
Step-by-step explanation:
First you bring over the added variable. 0.194185, and subtract it from 66. Then you divide your difference by 0.985897. This gives you 66.74715005725
The answer is C. If the original equation is 10+20 for one swing, you multiply that by 3 to get the cost of three swings
