You have that formatted a bit weird
A function is something where i can input a number and get ONE y output 
so f(x) = x + 2
I can input 4
f(4) = 4 + 2
f(4) = 6

The sum of two numbers is 43. The sum of 3 times the larger and 6 times the smaller is 174. Find the numbers.
EastWind [94]

Answer:

x = 28,  y = 15

Step-by-step explanation:

You can solve this by representing these two statements into equations and solving for one of the variables. Here, I will use x and y, where x > y.

x + y = 43

3x + 6y = 174

Now, we can choose which variable to solve for. I'm going to isolate one of the variables in the first equation by subtracting y from both sides.

x = 43 -y

Using this equation, we can substitute it for the x variable in the second equation like this:

3(43 -y)+6y=174

Simplifying this, we get

129 + 3y = 174

Solving this, we find that y = 15. We can plug this into one of the equations to find x:

x + 15 = 43

Solving for this equation, we find that x = 28.

Answer:

18 cm²

Step-by-step explanation:

The area labelled A is a triangle.

The area (A) of a triangle is calculated using the formula

A = \frac{1}{2} bh ( b is the base and h the height )

here b = 9 and h = 4 ( the same height as the rectangle ), thus

A = \frac{1}{2} × 9 × 4 = \frac{1}{2} × 36 = 18 cm²

Dirk is a broker who earns $41,000 annually, 3.5% commission on his clients’ investments of $2.4 million, and a fee of $5.25 on
Scilla [17]

Answer:

His annual earnings is $131,562.50

Step-by-step explanation:

Here, we want to calculate Dirk’s total annual earnings.

We have three things to add together;

Annual earnings, commission and fees

Annual earnings is already stated = $41,000

Commission

= 3.5% of $2.4 million

= 3.5/100 * 2,400,000 = $84,000

Fees

= $5.25 * 1,250 = $6562.50

Total earnings will be;

41,000 + 6562.5 + 84,000 = $131,562.50
