It is a function, because you are associating one and exactly one y-value to each x-value.
First, multiply both sides by 1000.
1000*c = w*t*c
Since c is on both sides, they cancel each other out
1000 = w*t
Divide both sides by w.
1000/w = t
Answer:
B) $30.87
Step-by-step explanation:
28.45*0.085=2.41825
When rounded to the nearest cent, you get 2.42.
28.45+2.42=30.87
The total cost after tax is $30.87.
Answer:1$ cards = 11 cards 3$ cards= 13
Step-by-step explanation:the first equation is -x-y=-24 and the second is x+3y=50. Solving them as a system will get 2y=26 to y=13 then plug in 13 to the y for -x-y=-24 to get 11. Mr jacobs is hard I know lol. Use elimination by subtraction and keep the first equation as x+y=24 and then flip to negative
Answer:
Step-by-step explanation:
Exponents with fractions in them are really just radical notation in a different form. You've probably seen the square root sign.
That can be written as
x^(1/2)
...and when you take an even root of a negative number, there is no real answer. (2 is an even number).
Looking at the answer choices here, we can see that B and D use even roots, so they will give non-real answers.
So, A and C are the answer choices to select.
