Step-by-step explanation:
I did the math by adding
The number of months will Plant A be as tall as Plant B will be 16 months.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
You record the heights of two plants each month for 3 months. The table is given below.
Month Plant A Plant B
0 4 in 8 in
1 5.75 in 9.5 in
2 7.5 in 11 in
Let 'x' be the number of months and 'y' be the height of the planet.
Then the first equation is given as,
y - 4 = [(5.75 - 4) / (1 - 0)] (x - 0)
y = 1.75x + 4 ....1
The second equation is given as,
y - 8 = [(11 - 8) / (2 - 0)] (x - 0)
y = 1.50x + 8 ....2
From equations 1 and 2, then we have
1.75x + 4 = 1.50x + 8
0.25x = 4
x = 16 month
The number of months will Plant A be as tall as Plant B will be 16 months.

Use substitution to solve the system of equations.
Answer:
(0, 2)
Step-by-step explanation:
12.5x + 2.5y = 5
y = 5x + 2
12.5x + 2.5(5x + 2) = 5
12.5x + 12.5x + 5 = 5 (distribution property)
25x = 0 (combined like terms)
x= 0
y = 5(0) + 2
y = 2
check
12.5(0) + 2.5(2) = 5
5 = 5
Yes
B)
I would use the first equation (y = 5x + 2) to substitute into the second equation (12.5x + 2.5y = 5) because it is already (y = ...) so it is easier to insert it into the second equation.

Answer: A=C+7
Step-by-step explanation:
Let’s say hypothetically C=6, then B would be 4 since you would have to subtract 2 and A would be 13 since 4+9=13
The difference between 13 and 6 is 7, but that would work with any number and i’m just using c=6 as an example to make the problem easier to understand

Find the mean median and mode of each data set (I NEED HELP PLEASE)
Answer:
there is no mode I’m only telling the mode
Step-by-step explanation:
the mode is the average amount of numbers there is 1 of each so no mode
Answer:
Mean: 94,227 (all the numbers added up) ÷ 9= 10,469.66
Median: 5,115
Mode: not defined (there are no numbers that repeat)
Step-by-step explanation:
Here are the definitions of mean, median and mode:
Mean: Adding all the numbers and then dividing them by the amount of numbers there are (ex. 1+2+3 --> 6 ÷ 3= 2)
Median: To find the median, you have to put all the numbers by each other. The number in the middle is the median (ex. 1,2,3,4,5 -> the median is 3. If there is an even amount of numbers: 1,2,3,4 then you average the two middle numbers; 2+3= 5 ÷ 2= 2.5)
Mode: The number used most (ex. 1, 2, 2, 4, 4, 4, 6. The mode is 4 since it's used 3 times.)
To solve this, put all the numbers together:
13,354; 12,450; 8,300; 9,705; 5,115; 5,106; 9,300; 11,245; 19,652

Nestor works at a garden center where he plants flowers. It takes him 2.5 hours to plant 15 flowers.
If Nestor continues working at the same rate, how many flowers will he be able to plant in 3.5 hours?
Answer: 22 1/2 flowers i think
Step-by-step explanation:
it takes 2.5 hours to plant 15 and hes gonna work for 3.5 more hours so 15/2 =7.5 , 7.5+15=22.5
The answer is 30 flowers because if you add 15+15 you get 30 and to get 3.5 you add 2.5 + 1.0 = 3.5, hope this helps! im sorry if it doesn't

-8 = 5x- x + 12 - 8
solve for x
Step-by-step explanation:
-8=5x-x+12- 8 we have to solve the equation.
[tex] \sf \implies - 8=5x-x+12- 8[/tex]
We have to combine number which do not have variables like + 12 and -8. we have to see these two numbers to left hand side and when we shift these two number left hand side the sign of these two number are also change.
[tex] \sf \implies - 8 - 12 + 8 = 5x - x[/tex]
Now, we have to Solve this. -8-12 = -20. We add these two numbers - 8 and -12 because - and - turns into + but. Now, we add this two numbers we get - 20. -20 + 8 = -12. We we get our answer that is -12 because minus and plus turns into minus.
[tex] \sf \implies - 12 = 4x[/tex]
We write 4x because we subtract 5x with x here single x means 1x. So, 5x - 1x we get 4x.
[tex] \sf \implies \cancel{ \dfrac{ - 12}{4} }= x [/tex]
[tex] \sf \implies \dfrac{ - 3}{1} = x[/tex]
[tex]\sf \implies - 3 = x[/tex]

a. Write an equation representing the amount of medication left in Tammy’s body after n hours.
b. How much medicine is left in Tammy’s body after 3 hours? 24 hours?
c. Create a graph to represent the medication in Tammy’s body over time.
d. Use your graph to estimate the half-life of this medication.
e. What is the range of this situation? What does this tell you about how long it takes for the medicine to completely leave the body?
Answer:
a) M(n)=500−0.10n
b) 499.7, and 497.6 milligrams
c) The table and graph are below
d) 2500 hours
e) Range [0,500] milligrams

Other answers are below
Step-by-step explanation:
a) The equation representing the amount of medication, M, left in Tammy's body after n hours
M(n)=500−0.10n
b) When n=3 hours we have
M(3)=500−0.10(3)=499.7 mg
When n=24 hours we obtain
M(24)=500−0.10(24)=497.6 mg

d. Use your graph to estimate the half-life of this drug.
According to the table and the graph, the half-life is 2500 hours.
M(2500)=500−0.10(5000)=250 milligrams
e. What is the range of this situation?
From the time it is ingested until it is completely assimilated, 500 hours elapse
Range [0,500] mg
What does this tell you about the time it takes for the drug to completely leave the body?
500 hours divided by the 24 hours of the day is approximately
550/24 = 208.33 days or approximately 2008.33/30 = 7 month

It's a very simple diagram but basically b is where the line cuts into the vertical y line (so in this case 0). m is then how many x there are per y. In this case it's just one.
Answer:
y=x
Step-by-step explanation:
y= mx+b
Pick any points that are on the line; for example (1,1) and (2,2)
for (x1=1, y1=1) and (x2=2, y2=2)
m = (y2-y1) /(x2-x1) = (2-1)/(2-1) = 1/1 = 1
If slope m = 1 then the equation is y = x+b now
Pick any point that is on the line again and substitute the coordinate in our equation to find b (the y-intercept) ; for example point (0,0) is on the line.
y = x+b, for (x=0, y=0) is
0 = 0 +b
0 =b
The equation in the slope intercept form of the given line is y = x, because the slope m=1 and the y-intercept , b=0
