We are given
The equation that models this trip is T= 36x + 60
T represents the total cost for the group to take the trip and
X equals the number of people going
we know that
Domain is all possible values of x for which any function is defined
Since, number of people can neither be negative nor in decimals
so, x can not be negative or in decimals
now, we will check each options
option-A:
x=40
This is positive and whole number
so, this can be domain
so, this is TRUE
option-B:
x=60
This is positive and whole number
so, this can be domain
so, this is TRUE
option-C:
0< x< 40
It also includes decimals numbers
and we know that
x can not be in decimals
so, this is FALSE
option-D:
0< x< 39
It also includes decimals numbers
and we know that
x can not be in decimals
so, this is FALSE
<h3><u>
The value of y is 1.6</u></h3><h3><u>
The value of x is 4.5</u></h3>
By elimination:
2x + 5y = 17
6x - 5y = 19
<em><u>We can add the second equation to the first in order to isolate one variable.</u></em>
(2x + 5y) + (6x - 5y)
8x = 17
<em><u>Because we added the left side, we have to add the right side here as well.</u></em>
17 + 19 = 36
8x = 36
<em><u>Divide both sides by 8</u></em>
x = 4.5
We can plug this value back into the original equation to find the value of y.
2(4.5) + 5y = 17
9 + 5y = 17
<em><u>Subtract 9 from both sides.</u></em>
5y = 8
<em><u>Divide both sides by 5.</u></em>
y = 1.6

Step-by-step explanation:
5.5lbs(16oz/lb)+3lbs(16oz/lb)+6oz=142 oz or if you prefer
142oz(lb/16oz)=8 0lb+0.875 lb(16oz/lb)=8 lb, 14oz
Answer:
If your trying to answer for X, here is how you do it.
For the equation '' Y = 10x + 20 '', isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:
X = Y/10 − 2
Or
X = − 2
For the other equation " Y = 20x + 10 ", it's the exact same thing. Isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:
X = Y/20 − 1/2
Or
X = −
