I don't know how you expand it but the answer is 3x + 25 unless that's expanding.
Answer:
12 months in a year
6 is half a month so we're going off of 6 months.
So:
821*0.15= 123.15
821- 123.15= 697.85
697.85*0.15= 104.6775
697.85-104.6775= 593.1725
593.1725*0.15= 88.975875
593.1725-88.975875= 504.196625
504.196625
*0.15= 75.62949375
504.196625- 75.62949375= 428.56713125
428.56713125*0.15= 64.2850696875
428.56713125-64.2850696875
= 364.282061562
364.282061562*0.15= 54.6423092344
364.282061562-54.6423092344
= 309.639752328
So its 310 fish.
Answer:
- Positive at (-9, 2)
- Negative at ( -oo, -9) or (2, + oo)
Step-by-step explanation:
<u>Given function</u>
<u>Getting zero's</u>
- -2x^2 - 14x + 36 = 0
- x^2 + 7x - 18 = 0
- x = ( -7 ± √(49 +72))/2 = ( -7 ± 11)/2
- x = - 9 and x = 2
<u>As the x^2 has negative coefficient, the function is positive between -9 and 2</u>
<u>And it is negative at:</u>
- x < -9 and
- x > 2
- or
- ( -oo, -9) or (2, + oo)
Answer:
y = - 7
Step-by-step explanation:
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (5, - 7) with y- coordinate - 7, thus
y = - 7 ← equation of horizontal line
857 x 132= 113,124
