Answer:
1/2x = 3*(27-12)
Step-by-step explanation:
Let x be the number
Is means equals
Difference means subtract
1/2x = 3*(27-12)
Answer:
time walking=1-t hrs
ditace is same
therefore 2.5*(1-t)=45*t
2.5-2.5t=45t
t=2.5/46.5 hrs
this has only one solution since it is in linear form
Answer:
In 4 months the cost of both gyms will be the same.
Step-by-step explanation:
At first we need to model the function to calculate the cost of the 2 gyms.
Slope-intercept equation of linear function

where
slope of line
y-intercept
Let linear function to calculate total cost of gym be:

where
total cost of gym
cost per month (slope)
number of months
start-up fee (y-intercept)
For Gym 1
,

For Gym 2
,

In order to find the number of months the cost of both gyms will be the same, we need to equate both functions and solve for number of months 


So,
In 4 months the cost of both gyms will be the same.
Answer:
(
, 0 )
Step-by-step explanation:
To find the x- intercepts let y = 0, that is
2x² + 3x - 2 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = - 4 and sum = + 3
The factors are + 4 and - 1
Use these factors to split the x- term
2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )
2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term
(x + 2)(2x - 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = 
The x- intercepts are (- 2, 0 ), (
, 0 )
Sales tax is a percentage of the sale price of an item that is then added on to the total price of the item.
Example:
let's say you are buying an item priced at $10.00 and the sales tax rate is 6%. Sales tax rates can vary from state to state and even within counties or cities.
