<h2>Answer:</h2>

A positive relation between two things means that they are proportional to each other. One affects the other thing.

1) Smoking and cases of lung cancer. This is positive. As smoking affects lungs and can cause lung cancer. So, with increased smoking comes the increased risk of lung cancer thus increasing cases of lung cancer.

2) Amount of time spent at school each day and number of text sent per day - These two events are independent of each other. They are not based on each other. Hence, no relationship here.

A negative relation implies that if one thing increases, the other decreases.

3) The number of licks taken and the size of the Tootsie Pop. This is negative. As the number of licks increases, the size of the pop decreases.

Graph the equation on the coordinate plane.<br><br><br><br> y = 4x+4

Alla [95]

To graph the equation of the line, find the x-intercept and the y-intercept of the function

we have

$y=4x+4$

we know that

The x-intercept is the value of x when the value of y is equal to zero

The y-intercept is the value of y when the value of x is equal to zero

Step 1

<u>Find the x-intercept</u>

For $y=0$

$0=4x+4$

$4x=-4$

$x=-1$

the x-intercept is the point $(-1,0)$

Step 2

<u>Find the y-intercept</u>

For $x=0$

$y=4*0+4$

$y=4$

the y-intercept is the point $(0,4)$

Step 3

Graph the points and draw the line

see the attached figure

therefore

Dexter read 11 science fiction books and 5 history books. Lena read 9 science fiction books and 4 history books. Compare the stu

Soloha48 [4]

Answer:

1. $Dexter = 11:5$ $Lena = 9:4$

2. $Dexter = \frac{11}{5}$ $Lena = \frac{9}{4}$

3. $Dexter = \frac{44}{20}$ $Lena = \frac{45}{20}$

4. $\frac{45}{20} > \frac{44}{20}$

Step-by-step explanation:

Given

Dexter

$Science\ Fiction = 11$

$History = 5$

Lena

$Science\ Fiction = 9$

$History = 4$

Solving (1): Write as ratio

Represent Science Fiction with S and History with H

For Dexter;

$Ratio = S : H$

$Dexter = 11:5$

$Lena = 9:4$

Solving (2): Write ratio as fraction

$Fraction = \frac{S}{H}$

$Dexter = \frac{11}{5}$

$Lena = \frac{9}{4}$

Solving (3): Write as a common denominator

$Dexter = \frac{11}{5}$

Multiply by $\frac{4}{4}$

$Dexter = \frac{11}{5} * \frac{4}{4}$

$Dexter = \frac{44}{20}$

$Lena = \frac{9}{4}$

Multiply by $\frac{5}{5}$

$Lena = \frac{9}{4} * \frac{5}{5}$

$Lena = \frac{45}{20}$

Solving (4): Compare both fractions

By comparison;

$\frac{45}{20}$ is greater than $\frac{44}{20}$

So, we have:

$\frac{45}{20} > \frac{44}{20}$
