The quotient, or resulting number, will decrease.
Answer:
Step-by-step explanation:
p^2-8p-9
factor out the trinomial
(p-9)(p+1)
Therefore, she's incorrect. Because (p-1)(p+9)=p^2-p+9p-9=p^2+8p-9 and that's different from p^2-8p-9.
I think what you meant was
(2x - 5)² = 11 -- (1)
Square root both sides of (1), i.e.
√(2x - 5)² = ± √11 -- (2)
From (2), we have
2x - 5 = ± √11 -- (3)
By adding 5 to both sides in (3), we have
2x = 5 ± √11 -- (4)
Divide both sides of (4) by 2, and we obtain
x = (5 ± √11)/2 -- (5)
From (5), the solution set of (1) is
x = (5 + √11)/2, (5 - √11)/2 ...Ans.
Hi there!
Your question:
Sales fall from 300 per week to 270 per week what's the percentage change?
My answer:
The formula for calculating percent change is as follows:
[(y2 - y1)/y1]*100=your percent change
y2= first value
y1=second value
Plug the numbers in:
[(300-270)/300]*100
[30/300]*100
0.1*100
10
Therefore, the percent change is 10%
Hope this helps! Let me know if it's incorrect so I can fix it:)
Answer: (0,10)
Step-by-step explanation: y=mx+b
y=12.5x+10
0=12.5x+10
10 is y because its on the outside
