Answer:
x^2 - 14x + 49
Step-by-step explanation:
(x - 7)(x - 7) = x^2 -7x - 7x + (7)(7)
Answer:
Step-by-step explanation:
Convert 6 hours to minutes so that 6 hours and 16. 3 minutes can be in the same units.
Since 1 hour = 60 minutes, then 6 hours = 6 x 60 minutes = 360 minutes
Since the insect has more minutes to crawl (360 minutes), then we expect more inches to be covered. Therefore, the ratio is 360 minutes to 16.3 minutes
= 360 minutes : 16.3 minutes
= 360 : 16.3
Now express the ratio as fraction and relate it with 30 inches
= 360/16.3 x 30/1
= 10800/16.3
= 662 .576687 and this is approximately 650 inches
Answer = 650 = (C)
Answer:
Y'=3xy-3x-12
Y'=F(-2,-1)=0
Step-by-step explanation:
The function of the equation at the point (-2,-1)
is where the equation make the function go to zero:
Y'=3xy-3x-12
Y'=F(-2,-1)=[3(-2)(-1)]-[3(-1)]-12
F(-2,-1)=[6]-[-6]-12
F(-2,-1)=6+6-12
F(-2,-1)=12-12
F(-2,-1)=0
Solving for y
3xy-3x-12=0
y=4/x+x
Making y=0
So the values make the function go to zero
Answer:
The answer is 30
Step-by-step explanation:
If you were to do 50% of 30, it would be 15 students that are girls. There's 18 students that are girls though, so the extra 10% would make 18 students in the class girls. The remaining 40% would be 12 boys. So basically you're taking 10% from one side and putting it in the other because 50% of 30 is 15 (well this is at least how I would do it, I don't know how others would do it though)
