Answer:
Both situations can be modeled using linear functions
The rate of change of the function that models Regina's towing charge is 2.5
The y-intercept of the functions that model both situations represents the hook up fee
Step-by-step explanation:
Let
x -----> the number of miles towed
y ----> the total charge in dollars
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value (value of y when the value of x is equal to zero)
we have
Sam’s Towing
In this case the slope of the linear equation is equal to the unit rate
The unit rate is $2.00 per mile towed
so
The y-intercept is equal to the charge per fee
so
therefore
the linear equation is
Regina’s Towing
In this case the slope of the linear equation is equal to the unit rate
The unit rate is $2.50 per mile towed
so
The y-intercept is equal to the charge per fee
so
therefore
the linear equation is
Verify each statement
case 1) Both situations can be modeled using linear functions
The statement is true
See the explanation
case 2) The y-intercept of the function that models Sam's Towing charges is 2
The statement is False
The y-intercept of the function that models Sam's Towing charges is $57
case 3) The rate of change of the function that models Regina's towing charge is 2.5
The statement is true
See the explanation
case 4) The y-intercept of the functions that model both situations represents the hook up fee
The statement is true
See the explanation
case 5) The rate of change of the functions that model both situations represent the miles traveled per hour
The statement is False
The rate of change of the functions that model both situations represent dollars by mile towed
The expression 8x + 2(3y) represents the total amount, in dollars, that Davellyn spent on tank tops and scarves, where x represents the number of tank tops she bought and y represents the number of scarves she bought. Which statement must be true about the amount Davellyn spent?
She spent 8x dollars on scarves.
She spent 8 dollars for each scarf.
She spent 6y dollars on scarves.
She spent a total of 14 dollars.
Answer:
She spend 6y dollars on scarves.
Step-by-step explanation:
The question states that y represents the number of scarves she bought, so the first and second statements would be incorrect. You don't know how much she spent in total, so the fourth statement would also be wrong. So it's the third statement.
Also, you can just do 2*(3y), which is 6y.

You separate 42 bulbs of garlic into two groups:one for planting and one for cooking. You will plant 3 bulbs for every 4 bulbs that you will use for cooking. Each bulb has about 8 cloves. How many cloves of garlic will you plant?
Answer:
144 cloves
Step-by-step explanation:
You separate 42 bulbs of garlic into two groups:one for planting and one for cooking.
We have a ratio of planting to cooking
Planting : Cooking
You will plant 3 bulbs for every 4 bulbs that you will use for cooking.
Hence: 3 : 4
The total of their proportion = 3 + 4 = 7
Hence:
The number of garlic you plant =
3/7 × 42 = 18 bulbs of garlic
The number of garlic you use to cook =
4/7 × 42 = 24 bulbs of garlic
We are also told that:
Each bulb has about 8 cloves. How many cloves of garlic will you plant?
From the calculation above , we know the number of bulbs of garlic been planted
= 18 bulbs.
Hence:.
1 bulb = 8 cloves
18 bulbs = x
x = 8 cloves × 18 bulbs
x = 144 cloves
Therefore, you will plant 144 cloves of garlic

The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a retail price of $125. We need to find the wholesale (original) price of this bike. What percent of the wholesale (original) price is the retail price?
Answer:
Wholesale Price = $96.15Retail price percentage = 130%Step-by-step explanation:
Wholesale price was marked up by 30% and became $125.
Assume wholesale price is x. Expression will be;
125 = x + (30% * x)
125 = 1.3x
x = 125/1.3
x = $96.15
Retail price percentage = 125/96.15
= 1.30
= 130%

a rectangle is 6 times as long as it is wide. the perimeter is 140 cm. find the area of the rectangle. round to the nearest tenth if necessary.
Answer: [tex]w = 10[/tex]
Step-by-step explanation:
Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.
Step 1: Let 6w will be our length and let the perimeter be 140 cm.
[tex]6w, P = 140 cm[/tex]
Step 2: Perimeter means that you add up all the 4 sides of the rectangle.
[tex]P = 140 = w + w + 6w + 6w = 14w[/tex]
[tex]P = 140, 14w[/tex]
Step 3: Divide both sides 14 to get the single w variable.
[tex]\frac{140}{14} = \frac{14w}{14}[/tex]
Step 4: Simplify.
[tex]10 = w[/tex]
Step 5: Flip sides.
[tex]w = 10[/tex]

The Gonzalez's updated their bedroom by purchasing a new lamp for $89.95 and a comforter set for $239.99. They paid 6.5% sales tax on their purchases. If the Gonzalez's paid $351.72 total, determine if they paid the correct amount.
Answer:
Not exactly
Step-by-step explanation:
Cost lamp = $89.95Cost of comforter set = $239.99Sales tax = 6.5%Total payment:
($89.95 + $239.99)*1.065 = $351.39Total amount is a little different:
$351.72 vs $351.39Prove that (x+y)(x-y)+(y+z)(y-z)+(z+x)(z-x)=0
Answer:
x=0 x=y=z. with these presumed variable amounts, one can conclude that the equation you asked is equivalent to 0
Answer:
Step-by-step explanation:
(x+y)(x-y)+(y+z)(y-z)+(z+x)(z-x)
=x²-y²+y²-z²+z²-x²
