Answer:
0.3656 :)
Step-by-step explanation:
You said that 'A is 30' right there in the equation
so it would be
Xsquared=30
Answer:
<u>$211.50</u>
Step-by-step explanation:
Initially:
21 hours per week at 8.25 per hours means:
21 * 8.25 = 173.25 dollars per person
16 person = 16 * 173.25 = $2772 (total)
2nd phase:
2 more cashier = 16 + 2 = 18 cashiers
Per hour 0.25 more, so 8.25 + 0.25 = $8.50 per hour
1.5 hrs less than 21, so 21 - 1.5 = 19.5 hours
Hence,
18 * 19.5 * 8.50 = $2983.50 (new total)
Change in money paid = 2983.50 - 2772 = $211.50
Answer is choice C) 4x^2-3x+9
You list off the terms in a way where the largest exponent term comes first, then the second largest exponent is next, and so forth. Note how the last term 9 is the same as 9x^0. The term 3x is equivalent to 3x^1. So what we really have is 4x^2-3x^1+9x^0. The exponents count down: 2, 1, 0
Answer:
<h2>7y² - 6y -17</h2>
Step-by-step explanation:
(-2y^2-11y-7)-(-9y^2-5y+10) (firstly, we remove the brackets)
-2y^2 - 11y - 7 + 9y^2 + 5y - 10
= (-2y^2 + 9y^2) + (-11y + 5y) + (-7 - 10)
= (7y²) + (-6y) + (-17)
