Answer:
100
Step-by-step explanation:
because 100 divided by 5 is 20
I believe it is asking for x so I will be finding the value of x.
X = 4, work is shown below:
−2x=−3x+12−2x
Step 1: Simplify both sides of the equation.
−2x=−3x+12−2x
−2x=−3x+12+−2x
−2x=(−3x+−2x)+(12)(Combine Like Terms)
−2x=−5x+12
−2x=−5x+12
Step 2: Add 5x to both sides.
−2x+<u>5x</u>=−5x+12+<u>5x</u>
3x=12
Step 3: Divide both sides by 3.
3x/3 =1 2/3
x=4
Answer:
Step-by-step explanation:
[{((7^2)+1)-5}*3]
=[{(49+1)-5}*3]
=[{50-5}*3]
=[45*3]
=135
Answer:
9,000
Step-by-step explanation:
Answer: C. a set of input values
The domain is the set of allowed x values, aka input values.
With fairly many domain problems, one thing to look out for are things like potential division by zero issues. For example, if you had the function f(x) = 2/(x-3), then we want to avoid the denominator x-3 from being zero. Because x = 3 makes x-3 equal to zero, this means we must kick x = 3 out of the domain; however, any other real number will work. This example function therefore has the domain of any real number but 3.
Square roots are another thing that often comes up with domain problems. One example could be g(x) = sqrt(x+5). We'd want the x+5 to never be negative. Solving leads to to tell us what set of input x values we can plug in: namely anything -5 or larger.
Other types of domain problems can occur, but those two types are most common in my experience.
