Answer:
ur correct u got it.
Step-by-step explanation:
A plant is already 13 centimeters tall, and it will grow one centimeter every month.
Let H be the plant's height (in centimeters) after M months.
Write an equation relating H to M. Then graph your equation using the axes below.
Answer:
H = M + 13
Step-by-step explanation:
Each month will add 1 cm to the height which is 13
3(a+b)+15-a+2b=
Need answer
Hey there!
“3(a+b)+15-a+2b”
First DISTRIBUTE
3(a) + 3(b) + 15 - a + 2b
3(a) = 3a
3(b) = 3b
New EQUATION
3a + 3b + 15 - a + 2b
COMBINE your LIKE TERMS
(3a - a) + (3b + 2b) + (15)
~NOTE: “a” is understood as an invisible 1!~
(3a - 1a) = 2a
(3b + 2b) = 5b
(15) = 15
Therefore, your answer is: 2a + 5b + 15 ☑️
Good luck on your assignment and enjoy your day!

What function matches the table
The Clark County Sheriff’s Department schedules police officers for 8-hour shifts. The beginning times for the shifts are 8:00 a.m., noon, 4:00 p.m., 8:00 p.m., midnight, and 4:00 a.m. An officer beginning a shift at one of these times works for the next 8 hours. During normal weekday operations, the number of officers needed varies depending on the time of day. The department staffing guidelines require the following minimum number of officers on duty:
Time of Day Minimum No. of Officers on Duty
8:00 a.m.–noon 7
Noon–4:00 p.m. 6
4:00 p.m.–8:00 p.m. 9
8:00 p.m.–midnight 7
Midnight–4:00 a.m. 4
4:00 a.m.–8:00 a.m. 6
Determine the number of police officers that should be scheduled to begin the 8-hour shifts at each of the six times to minimize the total number of officers required. If your answer is zero, enter “0”.

8:00 p.m.
Midnight

Answer:
The number of policemen Officers starting each shift is given as follows;
Starting Time [tex]{}[/tex] Officers Starting
8:00 a.m. [tex]{}[/tex] 3
Noon [tex]{}[/tex] 3
4:00 p.m. [tex]{}[/tex] 6
8:00 p.m. [tex]{}[/tex] 1
Midnight [tex]{}[/tex] 3
4:00 a.m. [tex]{}[/tex] 4
Step-by-step explanation:
The given parameters are;
The Time of the Day [tex]{}[/tex] Number of Officers
8:00 a.m. --- Noon [tex]{}[/tex] 7
Noon --- 4:00 p.m. [tex]{}[/tex] 6
4:00 p.m. --- 8:00 p.m. [tex]{}[/tex] 9
8:00 p.m. --- midnight [tex]{}[/tex] 7
Midnight --- 4:00 a.m. [tex]{}[/tex] 4
4:00 a.m. --- 8:00 a.m. [tex]{}[/tex] 6
From the table, we have;
The total number of hours worked = (7 + 6 + 9 + 7 + 4 + 6) × 4 = 156 hours
The approximate number of policemen = 156/8 = 19.5 ≈ 20
Let a, b, c, d, e, and f be the number of policemen that start their 8 hour shift starting from 4:00 a.m.
Let b be the number of policemen that start their 8 hour shift at 4:00 a.m.
∴ a + b = 7, b + c = 6, c + d = 9, d + e = 7, e + f = 4, f + a = 6
Given that there are 6 variables, by noting that the maximum value of the variables will be about 5, and by trial and error, we have
a - c = 1
d - b = 3
c - e = 2
d - f = 3
a - e = 2
a - f = 1
Whereby a + b + c + d + e + f = 20
Therefore, we have;
b = 3, d = 6, f = 3, a = 4, c = 3, e = 1
Which gives;
Starting Time [tex]{}[/tex] Officers Starting
8:00 a.m. [tex]{}[/tex] 3
Noon [tex]{}[/tex] 3
4:00 p.m. [tex]{}[/tex] 6
8:00 p.m. [tex]{}[/tex] 1
Midnight [tex]{}[/tex] 3
4:00 a.m. [tex]{}[/tex] 4

The population of a town is 13,000. It decreases at a rate of 5% per year. In about how many years will the population be less than 12,000?
Answer:
2 years
Step-by-step explanation:
13000 X 0.05 = 650
13000 - 650 = 12350 year 1
12350 X 0.05 =617.5
12350 - 617.5 =11732.5 year 2

3x+8=3x+____
Which value could you write in the blank above that would make the equation have one solution?
a.2x
b.8
c.7
Answer:
2x
Step-by-step explanation:
Think about it. Adding 8 would make the equation: 3x+8=3x+8. That has infinite solutions. if you made it 7, it would be 3x+8=3x+7, which is impossible.
Therefore, it must be 2x, which would make the equation 3x+8=5x.
Let's check: 3x+8=5x
8=2x
4=x

Create a table of values for each given function, turn them into coordinate pairs, graph on the coordinate plane, and then connect the pints. Choose points carefully so that they fit on the given coordinate plane.
Answer:
y points are 0, 1, 2, and 3 for x points 0, 2, 4, 6
Step-by-step explanation:
if a carpet is advertised at $20 per square yard, what is the cost per square foot?
Answer:
$2.22
Step-by-step explanation:
3 ft = 1 yd, so (3ft)^2 = (1yd)^2. Thus, 1 yd^2 = 9 ft^2
$20 / 1yd^2 = ($20 / 1yd^2)(1yd^2 / 9ft^2) = $2.22 per square foot
^ = to the power of...
yd = yard
ft = foot
