1 answer:

3 0

Y = 3x/4 - 1

Taking (-1-2)/(0-4) gives the slope of the line to be 3/4. Substituting x = 0 gives the y-intercept as -1.

Quincy sold three times as many magazines as Olivia. Trenton sold two less than twice the number of magazines that Quincy sold.

Anastaziya [24]

Olivia sold 14 magazines.

Step-by-step explanation:

Total magazines sold = 138

Let,

Magazines sold by Olivia = x

Magazines sold by Quincy = y

Magazines sold by Trenton = z

According to given statements;

x+y+z=138 Eqn 1

Quincy sold three times as many magazines as Olivia.

y = 3x Eqn 2

Trenton sold two less than twice the number of magazines that Quincy sold.

z = 2y-2 Eqn 3

Putting value of y from Eqn 2;

$z=2(3x)-2\\z=6x-2\ \ \ \ Eqn\ 4$

Putting value of y from Eqn 2 and value of z from Eqn 3 in Eqn 1

$x+3x+(6x-2)=138\\4x+6x-2=138\\10x=138+2\\10x=140\\$

Dividing both sides by 10

$\frac{10x}{10}=\frac{140}{10}\\x=14$

Olivia sold 14 magazines.

Find the complement of the set given that

natima [27]

The complement of the set is {8, 9, 10, 11}

<h3>How to find the complement of the set?</h3>

The universal set is given as:

U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}.

The other set is given as:

{x | x is in N and x < 8}

The complement of the set is the set elements that are in the universal set, but not in the given set

The set {x | x is in N and x < 8} can be rewritten as

X = {0, 1, 2, 3, 4, 5, 6, 7}

So, the complement is

X' = {8, 9, 10, 11}

In February, Alec had 1,525 visitors to his website. In March, he had 1,385 visitors to his website. What is the percentage decr

Helga [31]

A proportion box can be used to solve this problem. First, we need to compute the difference or change in the original amount of visitors Alec had (in February) and the new amount of visitors (in March).

1,525 - 1, 385 = 140

We place this amount (140) in the top left of our box, and we place the original amount (1,525) in the bottom left of our box. We are looking for the percentage decrease, so that box in the upper right will stay empty. The number 100 always goes in the bottom right of our percent proportion box.

(The attached image will show an example of how to set this up).

Our last step is to cross multiply and divide.

140 x 100 = 14,000

14,000 ÷ 1,525 = 9.18

So, the percentage decrease of the number of visitors to Alec's website from February to March was 9.18%.
