Answer:
x = ± 
Step-by-step explanation:
Given
2x² - 9 = 11 ( add 9 to both sides )
2x² = 20 ( divide both sides by 2 )
x² = 10 ( take the square root of both sides )
x = ±
← exact solutions
Hey there!
1a. Let c=cost of dinner, 5=the # of people, and P=the cost of person
P=C/5
b. <span>P = (1000)/5 </span>
<span>P = 200
</span>
2a. For 1= 19, 2= 38, 57= and so on ( you just multiply the number of season by 19)
b. T= 19n
Assuming that Jeremy spent the entire $100 on the party supplies, here's the breakdown:
$100 - $30 = $70 remaining.
$70 - $10 = $60 remaining.
If he spent $60 on ten hats, and each hat was the same price, then each hat would have cost:

The equation is as follows:

Each hat was $6
I believe it's B. I hope this helps
The pairs of f(x) =-3x+5 can be found by putting value of x and getting f(x).
x=0, f(x)=5
X=-1, f(x) =3+5=8
x=1, f(x)= -3+5=2
So few ordered pairs arw (0,5) ,(1,2),(-1,8) etc.
