Mateo, a 31-year-old nonsmoker ($5.50), wants to purchase $100,000 in coverage for himself and $75,000 for his spouse, who is female, 30 years old, and does not smoke ($3.50). What will the insurance premium be?
A. $30.50
B. $32.50
C. $35.50
D. $36.00
Answers
Answer: B. $32.50
Step-by-step explanation:
The premiums listed in brackets are for every $25,000 of coverage.
Mateo wants a $100,000 coverage so we need to divide this by $25,000 to see how much more he will have to pay:
= 100,000 / 25,000
= 4
Mateo will have to pay 4 times the $5.50 for himself:
= 4 * 5.50
= $22.00
For his spouse who requires $75,000, he will have to pay:
= 75,000 / 25,000
= 3
= 3 * 3.50
= $10.50
Total Mateo is to pay for both his spouse and himself is:
= 22 + 10.5
= $32.50

PLLSSS HELP ME!! Which of the following functions accurately represents f??
Answers
Answer:
C. f(x) = x - 9 is the function that accurately represents f
Step-by-step explanation:
Plug in a value from the table to check which function is correct
1. Plug in x = 3 and check if you get -6.
A. f(3) = -4(3) + 12 = -12 + 12 = 0 -> 0 ≠ -6 so A is not the correct function
B. f(3) = 3(3) + 2 = 9 + 2 = 11 ≠ -6 so B is not the correct function
C. f(3) = 3 - 9 = -6 = -6 so C is the correct function
D. f(3) = -5(3) - 1 = -15 - 1 = -16 ≠ -6 so D is not the correct function

What is the constant?
What is the coefficient?
What is the variable?
What are the factors of 9x?
Answers
Answer:
the constant is 3 the coefficant is y and the varible is a and the factors of 9 are 18 and 27
Step-by-step explanation:
Answer:
The constant is 3
The coefficient is 12
The variables are both A and Y.
Disclaimer: I'm not sure about this next one, but I believe it's right.
9x factors are 3x, 1, and 9x.
If you wanted me to factor it, then it'd be something like 3x(3)
Step-by-step explanation:
A constant is a number that is by itself. Variables can't be constants. In this case, the only number that is by itself, that isn't a variable is 3. Therefore, 3 is the constant.
A coefficient is a number that accompanies the variable. Normally in a math equation, a variable is multiplied by a number. In this case, A is being multiplied by 12, so 12 is the coefficient.
The variable is the letter that represents any number. In this case, there are two variables, A and Y. They both represent numbers that can differ. So, A and Y are the variables.
The factors of 9x are 3x, 3, 1x, 1, 9x, and 9.
9 times 1x is 9x, 9x times 1 is also 9x.
3 times 3x is 9x, and 3x times 3 is again, 9x.

Answer: CD=7
Step-by-step explanation: By the definition of congruence, AB=CD.
Substitute the given expressions for AB and CD.
x+5=2x+3
Subtract x from both sides.
5=x+3
Subtract 3 from both sides.
2=x
Substitute x=2 back into the expression for CD and simplify.
CD=2(2)+3=7
Therefore, CD=7.

T(w) = 400/570 - W
a) What does T(150) mean in this situation?
b) At what value of w does the graph have a vertical asymptote? Explain how you know and what this asymptote means in the situation.

If the triangle and the rectangle have the same area, what is the value of n if m=6?
Answers
Answer:
n=3
Step-by-step explanation:
Triangle area: height*length*(1/2)
Rectangle area: width*length
Let's say x is the length, then our equation would be:
mx(1/2)=nx
we also know m is 6, so
6x(1/2)=nx
now we can solve for n
6x(1/2)=nx
3x=nx
3=n
n=3
