Since the denominators are already the same, subtract the numerators: 15 - 3. the answer is 12/8. this is reduced to **3/2**. if you need the answer in mixede number form, it is **1 and 1/2**

How many intersections are there of the graphs of the equations below?

kipiarov [429]

Answer:

The number of intersections = ∞

Step-by-step explanation:

Given the system of equations:

0.5 x + 5y = 6

3x + 30y = 36

By multiplying the first equation by 6

∴ 6 (0.5 x + 5y) = 6 * 6

∴ 3x + 30y = 36

So, Those equations are "Dependent", because they are really the same equation, just multiplied the first equation by 6.

So, the two equations are identical

Therefore: They have infinity number of solutions.

See the attached figure.

0.5 x + 5y = 6 ⇒ in black color

3x + 30y = 36 ⇒ in red color

If a number is an element of the set of real

kvasek [131]

Answer:

Option (A)

Step-by-step explanation:

A set of real numbers is a combination of both rational and irrational numbers.

But the elements in the sets of rational and irrational numbers will be different.

In short, rational and irrational number sets are the two subsets of real numbers.

Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.

Option (A) is the correct option.

With the ratio at 1:1, Point C appears to be the midpoint. Use the midpoint formula to ascertain (make sure of) whether Point C

Mila [183]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete because the coordinates of A, B and C were not given in the question.

However, the following explanation will guide you...

The midpoints, C of two point A and B is calculated as:

$C(x,y) = (\frac{x_1 + y_1}{2}, \frac{y_1 + y_2}{2})$

Where $(x_1, y_1)$ are the coordinates of A

and

$(x_2,y_2)$ are the coordinates of B

Take for instance, the given coordinates are

A(4,6); B(2,4) and C(3,5)

Then;

Plug in these values in the given formula:

$C(x,y) = (\frac{x_1 + y_1}{2}, \frac{y_1 + y_2}{2})$

$(3,5) = (\frac{4 + 2}{2}, \frac{6 + 4}{2})$

$(3,5) = (\frac{6}{2}, \frac{10}{2})$

$(3,5) = (3,5)$

In that case,

C is really the midpoint

To the b part: Explaining why ratio 1:1 is used

The reason is that both parts of the ratio are in equal proportion (1 and 1);

Because of this equal proportion, ration 1:1 is right to calculate the midpoint
