A dry cleaner charges $5.00 to clean one item. He offers to clean a second item for $4.50, and a third for $4.00. If he continues to subtract $0.50 for each additional item, how much will it cost to clean six items?
MARKING BRAINLEST IF HURRY
Answer:$2.50 to clean 6 items
Step-by-step explanation:
$5.00-0.5=$4.5= 2 items
$4.5-0.5=$4= 3 items
$4-0.5=$3.5= 4 items
$3.5-0.5=$3= 5 items
$3-0.5=$2.5= 6 items

A chain of retail computer stores opened 2 stores in its first year of operation. After 8 years of operation, the chain consisted of 206 stores. If the number of stores opening per year is increasing at an exponential rate, identify the continuous rate of growth. Round k to the nearest hundredth. *
Answer:
0.66
Step-by-step explanation:
The exponential growth equation is expressed as;
S(t) = S0e^kt
S(t) is the number of stores after t years
S0 is the initial number of stores
If a chain of retail computer stores opened 2 stores in its first year of operation then at t = 1, S(t) = 2. Substitute into the equation;
2 = S0e^k(1)
2 = S0e^k .... 1
Also if after 8 years of operation, the chain consisted of 206 stores, this means at t = 8, S(t) = 206. Substitute into the equation;
206 = S0e^k(1)
206 = S0e^8k .... 2
Next is to calculate the value of k
Divide equation 2 by 1;
[tex]\frac{206}{2} = \frac{S0e^{8k} }{S0e^k }\\103 = e^{7k}\\apply \ ln \ to \ both \ sides\\ln103 = lne^{7k}\\ln103 = 7k\\k = \frac{ln103}{7}\\k = \frac{4.6347}{7} \\k = 0.6621[/tex]
Hence the value of k to the nearest hundredth is 0.66
Jonathan wants to the new baseball game for his game console. The game costs $45.99. Of sales tax is 6%, write an equation to find the total cost of the game, represented as P.
Answer: See explanation
Step-by-step explanation:
Cost of game = $45.99
Sales tax = 6%
The equation to find the total cost of the game, represented as P will be:
P = 45.99 + (6% × 45.99)
= 45.99 + (0.06 × 45.99)
= 45.99 + 2.7594
= $48.7494
When a plumber is called, the cost of the service call is $50 for him to show up at your house, plus an additional $25 per hour.
What is the slope ?
y is the total cost of the service call and x is the number of hours the plumber is at your home
Answer:
The slope is 25
y=mx+b with m representing slope
y=25x+50
Step-by-step explanation:
can someone explain this to me:)
Answer:
B) m = 2 , b = -3
Step-by-step explanation:
b = y-intercept
The y-intercept is -3

WILL GIVE BRAINLIEST write an equation for the nth term of the arithmetic sequence and find the 100th term 14,19,24,29, ...
Answer: the nth term of the sequence 14, 19, 24, 29 is: 5n+9 so the 100th term of the sequence will be 509.
explanation below:
Step-by-step explanation:
to find the 100th term we will have to find the nth term of the sequence when we have the nth term we need to replace n with the term we need to find and multiply it with the number behind n then subtract or add the number and u will get ur answer.
I hope this helps
Answer:
an=9+5n
a100=509
Step-by-step explanation:
a1=14
19-14=5
24-19=5
29-24=5
d=5
an=a1+(n-1)d
an=14+(n-1)(5)
an=14 +5n -5
an=9+5n
an=a1+(n-1)(d)
a100=14+(100-1)(5)
a100=14+(99)(5)
a100=14+495
a100=509
or
an=9+5n
a100=9+5(100)
a100=9+500
a100=509
Tyler thinks that the relationship between the ages of the children in Family B can be described with 2m – 2y = 10, where m is the age of the middle child and y the age of the youngest. Explain why Tyler is right.
Answer:
m - y = 5 is equivalent to 2m - 2y = 10
Step-by-step explanation:
Given
m = age of middle child
y = age of youngest child
[SEE ATTACHMENT FOR COMPLETE QUESTION]
Required
Explain why Tyler is correct
From the question, we understand that m is 5 greater than y
This can be represented as
m = 5 + y
To explain why Tyler is correct, we simply solve the above expression.
First, subtract y from both sides
m - y = 5
Multiply both sides by 2
2 * (m - y) = 2 * 5
2m - 2y = 10
This implies that m - y = 5 is equivalent to 2m - 2y = 10
And that means, Tyler conclusion is correct

Question 5)
Given the points
(2, 0)(5, 5)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:0\right),\:\left(x_2,\:y_2\right)=\left(5,\:5\right)[/tex]
[tex]m=\frac{5-0}{5-2}[/tex]
[tex]m=\frac{5}{3}[/tex]
Therefore, the slope is:
[tex]m=\frac{5}{3}[/tex]
Question 6)
Given the points
(-1, 0)(-2, 3)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:0\right),\:\left(x_2,\:y_2\right)=\left(-2,\:3\right)[/tex]
[tex]m=\frac{3-0}{-2-\left(-1\right)}[/tex]
[tex]m=-3[/tex]
Therefore, the slope is:
[tex]m=-3[/tex]
Question 7)
Given the points
(-1, -1)(1, 3)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:-1\right),\:\left(x_2,\:y_2\right)=\left(1,\:3\right)[/tex]
[tex]m=\frac{3-\left(-1\right)}{1-\left(-1\right)}[/tex]
[tex]m=2[/tex]
Therefore, the slope is:
[tex]m=2[/tex]
Question 8)
Given the points
(2, 0)(-2, 4)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:0\right),\:\left(x_2,\:y_2\right)=\left(-2,\:4\right)[/tex]
[tex]m=\frac{4-0}{-2-2}[/tex]
[tex]m=-1[/tex]
Therefore, the slope is:
[tex]m=-1[/tex]
Question 9)
Given the points
(0, 1)(4, -2)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:1\right),\:\left(x_2,\:y_2\right)=\left(4,\:-2\right)[/tex]
[tex]m=\frac{-2-1}{4-0}[/tex]
[tex]m=-\frac{3}{4}[/tex]
Therefore, the slope is:
[tex]m=-\frac{3}{4}[/tex]
Question 10)
Given the points
(0, 2)(1, -3)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:2\right),\:\left(x_2,\:y_2\right)=\left(1,\:-3\right)[/tex]
[tex]m=\frac{-3-2}{1-0}[/tex]
[tex]m=-5[/tex]
Therefore, the slope is:

Answer:
y=2x+4
Step-by-step explanation:
2 is the slope, you can see that with rise over run. 4 is the y intercept
Answer:
y=2x+4
Step-by-step explanation:
Look at the y-axis if the point that touches the y-axis is 4
Then the slope is 2
you go down 2 which is -2 (Since down is negative)
and you go left 1 which is -1 (Since left is negative)
now the equation looks like this:
y=-2/-1x+4
Simplify: (negative and negative cancel each other out making it positive)
y=2x+5
