Answer:

The set {x | x is an even prime number, x<150} has 1 element.

Step-by-step explanation:

Prime Numbers: The numbers which have no factors other than 1 and the number itself are called prime numbers.  

Even Numbers are those numbers which are completely divisible by 2.

So, the only EVEN PRIME NUMBER = 2

Now, Set = {x | x is an even prime number, x<150}

So, the set has {2} as its only element.

Hence, the total elements in the set is 1.

Or, the set {x | x is an even prime number, x<150} has 1 element.

Answer: $2926.05

Step-by-step explanation:

Compounded interest follows the formula:

P(1 + r/n)^nt where P = principle, or starting contribution, R = Rate (Percentages converted to decimals), N = number of compounds per year, and T = number of years.

The Principle would be $2500

The Rate would be 2.64% or 0.0264

N would be 2, since it is semiannual

T would be 6, since this lasts 6 years.

When we plug it in, we see

2500(1 + (.0264/2))^(2)(6)

= 2926.053

In a real situation in the bank, they would give you $2926.05

5x + 7y = -29 y = x + 1
o-na [289]

Answer:

  (x, y) = (-3, -2)

Step-by-step explanation:

Perhaps this is a system of equations you want the solution for.

Since you have an expression for y, substitution is a viable approach.

  5x +7(x+1) = -29 . . . . . . substitute for y

  12x = -36 . . . . . . subtract 7 and simplify

  x = -3 . . . . . . . . . divide by 12

  y = (-3) +1 = -2 . . . use the expression for y

The solution is (x, y) = (-3, -2).
