You would do 157.5/35 to find how much gas she needs
157/35=4.5
She'll need 4.5gallons of gas
Absolute value function domain is all real numbers
absolute value has vertex of(0,-3)
and it opens up
means that the lowest y value is -3
highest is infinity
domain=-inifnity to infinity
range=-3 to positive initnify
the answer is C for the domain and B for the range
The first option,
both have to be negative, because they were originally both part of the one fraction, which was all negative.
For this case we have the following system of equations:
From the first equation we clear "x":
We substitute in the second equation:
We apply distributive property:
We add similar terms:
We add 65 to both sides:
We divide between 22 on both sides:
We look for the value of the variable "x":
Thus, the solution of the system is:
ANswer:
Dana:
Starts with 25 = 25
Spends 10 = 25 - 10 = 15
Received 50 = 15 + 50 = 65
New tires cost 75 = 65 - 75 = -10
Tracey:
Starts with 50 = 50
Gets gas for 25 = 50 - 25 = 25
Received 100 = 25 + 125 = 125
Purchased boots for 150 = 125 - 150 = -25
Tracey ends up with the least amount of money after their purchases.
Hope this helps! :)
