Answer:
10.294935
Step-by-step explanation:
i typed numbers
10 plays
Divide 2/5 and 4 by 2 to get 1/5 and 2
For every 1/5 of practice he teaches the ten 2 plays
5/5 = 1
So 5*2 = 10 plays
<span>TLDR: Equation is 5(10 + x) = 6x. x = 50, so Sheila deposited $50 each 6 trips. Sherri deposited $60 each 5 trips. Both of them deposited $300 in total.
</span>Sherri deposited $10 more into her bank account than Sheila each 5 times. Expression: 5(x + 10).
Sheila deposited money 6 times
Expression: (6)(x) or 6x
Put it all together and the equation is 5(x+10)=6x.
Solve by distributing the 5 on the right side of the equation 5(x+10) to get 5x + 50 = 6x. Subtract 5x on both sides of equation. 5x - 5x + 50 = 6x - 5x to get 50 = 1x. Divide by 1 on each side to isolate the variable. x = 50. Sheila paid $50 in each of her 6 deposits, so she deposited $300 in total. Check the equation by replacing x with 50.
Sherri paid $60 in each of her 5 deposits because 50 + 10 is 60. 60 by 5 is also $300.
So if you want to have a factored form...
If the zeroes are +4 and +8, you would write
(X-4) (x-8)
Then you would multiply it out to get to quadratic form...
So, (x-4)*(x-8)
X^2 - 12x + 32
Then you would plug it into the formula for axis of symmetry...
X= -b/2a
X=12/2 = 6
X=6
