Answer:

a) 2x + y =12, x = 9-2y. Solution: x=5 and y=2

b) x + 3y=16, 2x - y = 11

Solution: x = 7 and y= 3

c) 2x+ y = 11, x - 2y = - 7. Solution: x = 3 and y=5

d) y=11-2x, 4x - 3y=-11

Solution: x=2 and y=7

Step-by-step explanation:

a) 2x + y = 12

b) x = 9-2y

Substitution:

a) 2(9-2y)+y = 12

18 - 4y + y = 12

18-12 = 4y -y

6 = 3y

6/3 = y

y = 2 and

X = 9 - 2(2) = 5

Step-by-step explanation:

Because I think what you do is subtract every number by each other for example 9 minus 10, 11 minus 15, 13 minus 20 so on and so on and then when you get all the answers add them all together and that's your answer.

Linnea’s company’s revenue in 2017 as a percent of its revenue in 2016 is; 1.44%.

Now, we are told that her revenue in 2017 is 36/25 of her revenue in 2016.

To express this revenue as a percentage, we will multiply 36/25 by 100%.

⇒ 36/25 × 100%.

⇒ 1.44%

Thus, in conclusion Linnea’s company’s revenue in 2017 as a percent of its revenue in 2016 is 1.44%.

Using the vertical asymptotes, it is found that the function is graphed below is:

D. [tex]F(x) = \frac{1}{x(x - 3)}[/tex]

A vertical asymptote is a point of a function which is outside it's domain.

In this problem, the asymptotes are: [tex]x = 0, x = 3[/tex].

Hence, the denominator is: [tex]x(x - 3)[/tex], which corresponds to option D, and thus, the function is:

D. [tex]F(x) = \frac{1}{x(x - 3)}[/tex]

Ruben's score on the next test to raise his average (mean) to 77 is 89.

The average is the quotient of the total divided by the number of items involved.

The average is also known as the mean.

The mean is one of the values of central tendency.  Other values of central tendency include the mode and the median.

The number of biology tests taken by Ruben so far = 6

The mean score of the six tests = 75

The total score so far in the six tests = 450 (6 x 75)

The expected average for seven tests = 77

The total score for the seven tests = 539 (77 x 7)

The expected score for the seventh test = 89 (539 - 450)

Thus, Ruben is expected to score 89 for his average score to be 77.
