Answer:
im so so so sorry, but i dont know(possibly because im only in 7th grade with a sucky teacher)
Step-by-step explanation:
The answer is NO,because if you put 3 CDs or less in each shelf you only can put 15 (3*5=15), the same reason for both questions.
Answer:
Step-by-step explanation:
To evaluate the domains of the greatest integer function, the rule is that you always round DOWN to the next whole number.
f[[3.4]] = 3
f[[.8]] = 0
f[[-1.7]] = -2
f[[-3.5]] = -4
Always round down!! Just remember that and you'll be ok!
Answer:
2, 4
Step-by-step explanation:
Ok so for this you have to substitute. y=4 so you put a 4 where the y is. This becomes
4 - 3x = -2 We can already rule out (2,2) and (4,2) Why? Because the y is not a 4. So it’s gonna be either (0,4) or (2,4). Now, we have to find x. We have to isolate it. You do this by subtracting 4 from both sides.
4 - 4 - 3x = -2 - 4 Now Simplify
-3x = -6 Why -6? Because you can’t subtract a positive from a negative so it becomes -2 + -4. Since they are both negatives, you just add them together, then put the negative sign.
Now divide -3 from both sides. Which becomes
x = 2
The equation of circle can be given as :
(x-h)² +(y-k)²=r²
where (h,k) is center of circle and r is radius
the center is at (4,1) and radius =6
so equation becomes,
(x-4)² +(y-1)²=6²
(x-4)² +(y-1)²=36 is the equation of circle
