Answer:
21.50
Step-by-step explanation:
Let C = cost before markup
1.25 C = 26.88
C = 26.88/1.25 = 21.50
4 - (x+2) < -3(x+4)
4 -1(x) -1(2) < -3(x) -3(4)
4 - x - 2 < -3x -12
<u> +3x +3x </u>
<u />2 + 2x < -12
<u>-2 -2
</u> 2x < -14
<u /> <u> ÷2 ÷2 </u>
x < -7
assume that x = -8
4 - (-8 + 2) < -3(-8 + 4)
4 - (-6) < -3(-4)
4 + 6 < 12
10 < 12 the inequality is true.
Answer:
A. $3770
Step-by-step explanation:
The correct answer must be $3770 (not $3270), checking accounts and savings accounts are liquid assets. However, cars are not liquid assets because liquid assets are things that can be quickly turned into cash without losing much if any of their inherent value. In this case, the retirement account is not a liquid asset as it is designed to hold your money until retirement age, and given that Cesar is 35 years old so he has not reached retirement age.
So it would be 1.2=X-0.4 and solve to get your answer. Output means the y-intercepts.
Answer:
Domain= {
}
Step-by-step explanation:
The function given is: 
, and we are asked to find the Domain of it. Let's recall that the Domain of a function is the set of all x-values for which the function is defined (can be evaluated rendering a real number as result). So in order to find which x-values constitute such Domain, let's investigate for which x-values we can effectively evaluate the square root of "x+6".
Notice that the square root is not defined for radicands that are negative (less than zero). The only radicands that are allowed are those greater than or equal to zero. So that is exactly the condition we want to impose on the radicand: to be greater than or equal to zero (
). Our radicand is the expression: "x+6", so we write in math terms the necessary condition as:
and solve for "x" in the inequality (isolating "x" on one side:
The Domain of this function is therefore all those real "x" values that are greater than or equal to negative 6 ()
