For this case we have the following equation:

5x + 1 = 4y + 3

We must indicate an equivalent equation that allows to obtain the value of the variabale "x"

To do this, we clear x from the given equation:

We subtract 1 from both sides of the equation:

5x = 4y + 3-1\\5x = 4y + 2

We divide between 5 on both sides of the equation:

x = \frac {4y + 2} {5}

<u>Answer:</u>

The correct answer option is D. x=\frac{4y+2}{5}.

<u>Step-by-step explanation:</u>

We are given the two models that represent the following equation:

5x+1=4y+3

We are to determine whether which of the given equations in the answer options can be used to find the value of x.

To find the equation, we will make x the subject in 5x+1=4y+3.

5x=4y+3-1

5x=4y+2

x = \frac { 4 y + 2 } { 5 }

Therefore, the correct answer option is D.

A basketball-player scores a free-throw with probability 0.9. What is the probability that her first miss occurs on the 6th shot
-BARSIC- [3]

Answer:

Pr = 0.059049

Step-by-step explanation:

Given

p = 0.9 --- probability of scoring

Required

Probability that his first miss is his 6th shot

Let q represent the event that he did not score.

Using complement rule:

q = 1 - p = 1 - 0.9 = 0.1

The event that his first miss is his 6th is represented as:

p p p p p q ---- That he scoress the first 5 attempts

So, the probability is:

Pr = p^5 * q

Pr = 0.9^5 * 0.1

Pr = 0.059049

A parallelogram has coordinates A(1, 1), B(5, 4), C(7, 1), and D(3, -2). What are the coordinates of parallelogram A′B′C′D′ afte
saul85 [17]

Hey there! I'm happy to help!

First, we need to rotate our points 180° about the origin. To find the coordinates after such a rotation, we simply find the negative version of each number in the ordered pair, which can be written as (x,y)⇒(-x,-y).

Let's convert this below

A: (1,1)⇒(-1,-1)

B: (5,4)⇒(-5,-4)

C: (7,1)⇒(-7,-1)

D: (3,-2)⇒(-3,2)

Now, we need to translate these new points five units to the right and one unit down. This means we will add 5 to our x-value and subtract 1 from our y-value. This will look like (x,y)⇒(x+5,y-1). Let's do this below.

A: (-1,-1)⇒(4,-2)

B: (-5,-4)⇒(0,-5)

C: (-7,-1)⇒(-2,-2)

D: (-3,2)⇒(2,1)

Therefore, this new parallelogram has coordinates of A'(4,-2), B'(0,-5), C'(-2,-2), and D'(2,1)

Now you know how to find the coordinates of translated figures! Have a wonderful day! :D
