Which of the sets of ordered pairs represents a function?
A = {(2,-2), (5,-5), (-2, 2), (-5,5)}
B = {(4,2), (4,−2), (9, 3), (9, −3)}

Answer:

y = 1 [ y intercept (0,1) ]

x = -5/11 [ x intercept : (-5/11,0) ]

Explanation:

First split this compound equation into two seperate ones:

y = 11x + 6y = 11x + 6 →

{ y = 11x + 6y → -5y = 11x → [ y = -11/5x ]

[ y = 11x + 6 ] }

________

Then find the x point of intersection by substitution.

y = -11/5x → y = 11x + 6

-11/5x = 11x + 6

-11/5x - 11x = 6

-66x/5 = 6

-66x = 30

-11x = 5

x = 5/-11

x = -5/11

_______

Then find the y point of interesection by substituting the x solution in one of the equations.

x = -5/11 → y = -11/5x

y = -11/5(-5/11)

y = 55/55

y = 1

The x-intercept is x = - 6/11.

The y-intercept is y = 6.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

y = 11x + 6

Now,

The x-intercept means y = 0.

So,

y = 11x + 6

0 = 11x + 6

11x = -6

x  = - 6/11

The y-intercept means x = 0.

y = 11x + 6

y = 0 + 6

y = 6

Thus,

The x-intercept is x = - 6/11.

The y-intercept is y = 6.

Answer:

18 : 9 is the same thing as 18/9.

So if we want 1 : n  = 1/n

(18 / 18) / (9 / 18)

=> 1 / 0.5

=> 1 : 0.5

Therefore, n = 0.5 is the solution of the equation.

Thanks!!

Answer:

n = 0.5

Step-by-step explanation:

To answer this question, we must first figure out the ratio 18:9.

What is 18 compared to 9?

If you said that 18 is double the amount of 9, or that 9 is half of 18, you are correct.

Using this logic, we then need to make the variable 'n' in 1:n half of 1 in decimal form.

So, what is half of 1 in decimal form?

If you said 0.5 OR 0.50, you are correct! And that is your answer !

Answer:

Final Balance = 106.90$

Step-by-step explanation:

Using the simple interest formula I = prt.

The current balance after accumulated interest is B = I + p.

Given a principle of $100, time of 3 years, and interest rate of 2.3%.

I = (100$)(3y)(2.3%) = (100)(3)(2.3%) = (300)(2.3%) = (300)(0.023) = 6.90$

B (final balance) = 6.90$ + 100$ = 106.90$

Answer:

Step-by-step explanation:

Stephen : Gavin : Jim

3 : 1 : 2

We can say that this means the total amount of sweets get split between the 3 of them into 6 equal parts ( 3 + 1 + 2).

If Stephen gets 24 sweets, this means

3 parts = 24

So to find 1 part, divide 24 by 3.

1 part = 8 sweets

Now we can find the total by multiplying this by 6.

6 parts = 8 x 6 = 48 sweets.
