2x + 3y = 5x - y Complete the missing value in the solution to the equation. ( _ , 0 )

wariber [46]

Answer:

(4y/3, 0) or if there are no options, it's probably (0, 0)

Step-by-step explanation:

2x + 3y = 5x - y

So we are trying to find the missing value in the solution (_, 0)

We are looking for the x-intercept/root if the coordinate is in this way: (_, 0)

So to find the root, We are solving for x

2x + 3y = 5x - y

First, subtract 5x from bth sides

2x + 3y - 5x = 5x - y - 5x

2x + 3y - 5x = -y

Add like terms

-3x + 3y = -y

Now, subtract 3y from both sides

-3x + 3y - 3y = -y - 3y

-3x = -4y

Divide both sides by -3

-3x/-3 = -4y/-3

x = -4y/-3

We are not done yet because the answer above is not quite right. A negative number divided by a negative number results in a positive number.

So x = 4y/3

Now that we found x, we can input it to the coordinate

(4y/3, 0)

I put it on Sesmos graphing calculator and the answer seems to be (0, 0)

Assume a student shows up for EGR 280 completely unprepared and the instructor gives a pop quiz. Assume there are 6 questions, e

Kisachek [45]

Answer:

P=20%

Step-by-step explanation:

Let's suppose that each question in the test has one and only one correct answer. This means we have 1 desired outcome out of the total 5 desired outcomes. Therefore:

Probability=#of desired outcomes / #of possible outcomes

$P=\frac{1 correct}{5 opctions}$

$P=\frac{1}{5}$

P=0.20

P=20%

Using distributive property -1/6(6y+7)??

Solnce55 [7]

Hello!

The distributive property states, a(b + c) = ab + ac. Normally, we would simplify the values inside the parentheses first, and then multiply, but since these two values are not alike terms, we would need to use the distributive property.

-1/6(6y + 7) is also equal to -1/6(6y) + -1/6(7), so with that, we can simplify the expression.

-1/6(6y) + -1/6(7) can be simplified to -y + -7/6.

Therefore, using the distributive property, the answer is -y - 7/6.
