Answer:

( 0 , 3 )

Step-by-step explanation:

1. Way one of solving this problem

This equation is in standard form, one must get it to slope-intercept form to find the answer. In other words, one must solve for "y"

3x + 4y = 12

Manipulate the literal equation with inverse operations;

3x + 4y = 12

4y = 12 - 3x

/4      /4

y = - \frac{3}{4}x + 4

2. Way two of solving this equation

The y-intercept is when this line intercepts the y-axis, so "x" is zero. Substitute "0" in for "x", and solve to find the y-intercept

3x + 4y = 12

x = 0

3 (0) + 4y = 12

0 + 4y = 12

Inverse operations;

4y = 12

/4   /4

y = 3

Answer:

y-intercept = 3

Step-by-step explanation:

3x + 4y = 12

4y = -3x + 12

4y/4 = -3/4x + 12/4

y = -3/4x + 3

What is the explicit formula for the sequence?
Aleksandr [31]

Answer:

a_{n} = n - 2

Step-by-step explanation:

Note the difference between consecutive terms is constant, that is

0 - (- 1) = 0 + 1 = 1

1 - 0 = 1

2 - 1 = 1

3 - 2 = 1

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 1 and d = 1, thus

a_{n} = - 1 + n - 1 = n - 2

C: y=2x+7 D: y= 1/2x+7
CaHeK987 [17]
Remember that if lines are parallel, they will have the same slope. Also, the number added or subtracted in the equation is the y intercept, or the y value when the x=0. They gave you the point (0,-7) so really, they just gave you the y intercept. How nice!! That means you just use the same slope as the original and then add -7 to it to get your equation. With that knowledge, you can now easily identify the correct answer!!

Which answers are examples of the Law of Detachment? select all that occur If two angles are vertical angles, then they have the
Lina20 [59]

The law of detachment is a set of three sentences, such that:

Sentence 1 is a statement of the form If p, then q

Sentence 2 is a statement of the form p

Sentence 3 is a conclusion of the form q

Let's see which of the options follow the pattern indicated above:

Option A: If an object is a square, it is a parallelogram. The object is a square. The object is a parallelogram. - MATCHES THE ABOVE PATTERN. Hence, is an example of the Law of Detachment.

Option B: If two angles are linear pairs, the angles are supplementary. The two angles are linear pairs. Therefore, the angles are supplementary. - DOES NOT MATCH THE ABOVE PATTERN.

Option C: If it is snowing, the play will be cancelled. If the play is cancelled, the theater will refund the cost of admission. Therefore, if it is snowing, the theater will refund the cost of admission to the play. - DOES NOT MATCH THE ABOVE PATTERN.

Option D: If it is snowing, the play will be cancelled. It is snowing. Therefore, the play is cancelled. - MATCHES THE ABOVE PATTERN. Hence, is an example of the Law of Detachment.

Hence, option A and option D are examples of the Law of Detachment.
