A mom buys a water bottle and a jersey for each of the 10 players on the volleyball team. Each jersey costs $6.70. The mom spends a total of $221 for water bottles and jerseys. Enter an equation that modes the situation with u, the cost of one water bottle.
Answer:
one water bottle cost 15.4 dollars
Step-by-step explanation:
6.7 times 10 is 67
therefore the mom spent 67 dollars on jerseys
221 (total) minus 67 ( jersey) = 154
therefore she spent 154 dollars on water
154 divided by 10
=15.4
the water bottles cost 15.4 dollars

How do I convert 83, 000, 000 to a scientific notion?
Answer:
Scientific notion: 83M meanin million
Answer:
[tex]8.3[/tex] x [tex]10^7[/tex]
Step-by-step explanation:
83 000 000 × 1 = 83 000 000
But 1 can be written as [tex]\frac{10^7}{10^7}[/tex]
83000000 × [tex]\frac{10^7}{10^7}[/tex] = 83000000 × 1 = 83000000
[tex]\frac{83000000}{10^7}[/tex] x [tex]10^7[/tex] = 83000000 × 1 = 83000000
Divide the denominator of [tex]10^7[/tex] into 83000000
[tex]8.3[/tex] x [tex]10^7[/tex] = 83000000

Both Carlos and Irene's solution corresponds to the factored form of the original equation and are Hence correct
The graph shows the relationship between the number of years after a car is purchased
and the car's value
Which statement correctly describes the relationship shown in the graph?
A)
The car's initial value is $18,000, and the car's value increases $2,000 each year.
B)
The car's initial value is $18,000, and the car's value increases $6,000 each year
C)
The car's initial value is $30,000, and the car's value decreases $2,000 each year.
D)
The car's initial value is $30,000, and the car's value decreases $6,000 each year
Answer:
C. The car's initial value is $30,000, and the car's value decreases $2,000 each year.
Step-by-step explanation:
first I looked at the graph and saw that the y-intercept(car's initial value) was 30,000 which allowed me to eliminate A and B. Then found the slope by using the [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]= slope formula. [tex]\frac{24,000-30,000}{3-0}=\frac{-6,000}{3}=-2,000[/tex]. This tells us that the slope is -2,000 which means that the value decreases by 2,000 each month. So the correct answer is C.
The car's initial value is $30,000, and the car's value decreases by $2,000 each year. the correct answer would be an option (C).
What is the slope of the line?The slope of a line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
The given graph shows the relationship between the number of years after a car is purchased and the car's value.
As per the graph, we take two points (0, 30,000) and (6, 18,000)
Here slope of the given graph is equal to the car's value decreases by each year.
So slope = (18,000 - 30,000)/(6-0) = -12,000/6 = -2000
This means the car's value decreases by $2,000 each year.
Thus, the car's initial value is $30,000, and the car's value decreases by $2,000 each year.

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower
bed. The diagram shows the flower bed and its dimensions in feet.
4w? + 3w - 1
5w - 2
Which expression represents the area in square feet that the homeowner will cover with fertilizer?
Answer:
The answer is D
Step-by-step explanation:
The 4w^2 stays the same because there are no like factors, then you add the 5w and 3w then get 8w...-1+ (-2) is -3
The polynomial that represents the area in square feet will be 20w³ + 7w² - 11w + 2. Then the correct option is B.
What is a polynomial?A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed.
A mortgage holder is building a blossom bed on the lawn. He intends to put a layer of compost over the whole bloom bed. The chart shows the blossom bed and its aspects in feet.
4w² + 3w - 1 and 5w - 2
The polynomial that represents the area in square feet will be given as,
⇒ (4w² + 3w - 1) x (5w - 2)
⇒ 20w³ + 15w² - 5w - 8w² - 6w + 2
⇒ 20w³ + 7w² - 11w + 2
The polynomial that represents the area in square feet will be 20w³ + 7w² - 11w + 2. Then the correct option is B.

Jonny is writing a program for a video game. For one part of the game he uses the
rule given below to move objects on the screen. Showing all your work, give the output that the rule gives for the inputs.
(x, y) --> (x-8.2, y+3.6)
First input: (7.6, 9.3)
Second input: (10.5, -2.1)
Answer:
[tex](-0.6,12.9)[/tex]
[tex](2.3,1.5)[/tex]
Step-by-step explanation:
Given: For one part of the game, Jonny uses the rule [tex](x,y)[/tex] → [tex](x-8.2,y+3.6)[/tex] to move objects on the screen.
To find: outputs for the given inputs
Solution:
Given rule is [tex](x,y)[/tex] → [tex](x-8.2,y+3.6)[/tex]
Put the first input as [tex](x,y)=(7.6,9.3)[/tex]
Output is [tex](x-8.2,y+3.6)=(7.6-8.2,9.3+3.6)=(-0.6,12.9)[/tex]
Given rule is [tex](x,y)[/tex] → [tex](x-8.2,y+3.6)[/tex]
Now, put input the second input as [tex](x,y)=(10.5,-2.1)[/tex]
Output is [tex](x-8.2,y+3.6)=(10.5-8.2,-2.1+3.6)=(2.3,1.5)[/tex]
Answer:
(-3.2 , 12.3)
(0.7 , 3.6)
The rule :
(x, y)→(x−7.5, y+6.8)
For the x - coordinate ; Subtract 7.5
For the y - coordinate `; add 6.8
First input : (4.3, 5.5)
Output :
x = 4.3 - 7.5 = - 3.2
y = 5.5 + 6.8 = 12.3
Output = (4.3, 5.5) →(-3.2 , 12.3)
Second input : (8.2, -3.2)
Output :
x = 8.2 - 7.5 = 0.7
y = - 3.2 + 6.8 = 3.6
Output = (8.2, -3.2)→(0.7 , 3.6)
The outputs obtained are :
(-3.2 , 12.3) and (0.7 , 3.6)

What is the slope of a line parallel to the line whose equation is 6x - y = 1. Fully
reduce your answer.
Answer:
6x
Step-by-step explanation:
To find a parallel line, you will need to put everything into the slope intercept form(y=mx+b).
When you do this, you should get -y=-6x+1. You cannot have a negative y, so you will divide everything by -1 to get y=6x-1.
Two lines are parallel when their slope is the same. The slope in this equation is 6.
