Answer:
21y
Step-by-step explanation:
= 3(2y+5y)
= 3 × 7y
= 21y
That's it
Have a good day
Answer:
50y + 75x ≥ 1000 ;
50(15) ≥ 750;
x ≥ 4
y ≥ 15
Step-by-step explanation:
Given that :
Number of stickers sold = y
Cost of sticker = 50
Cost of bag tag = 75
Number of bag tags sold = x
Total worth of items sold ≥ 1000
1)
50y + 75x ≥ 1000
2.)
To make atleast 15 stickers
y ≥ 15
Atleast 15 stickers :
50(15) ≥ 750
3.)
A possible solution :
50(15) + 75(x) ≥ 1000
750 + 75x ≥ 1000
75x ≥ 250
x ≥ 3.33
x ≥ 4
y ≥ 15
Answer:
Step-by-step explanation:
A sample of bacteria is decaying according to the half-life model f(t) = Ne -0.226t, where N is the initial sample size and t
is time in hours. At t = 4, there are 25 bacteria remaining. What was the initial sample amount? Round your answer to the
nearest whole number, and do not include units.

Answer:
The center is:
(2, -4)
Step-by-step explanation:
We have the following equation
The general equation of a circle has the following form
Where r is the radius and the point (h, k) is the center of the circle
To transform the given equation in the general equation of a circumference we must use the method of square completions
Step 1
<u>Step 2</u>
<u> </u>Add and subtract 
For an equation of the form
<u>Step 3 </u> Factor the expressions within the parentheses
<u>Step 4 Simplify</u>
Finally
The center is:
(2, -4)
