Answer : Graph D

Question says negative linear relationship. It means the slope is negative.

Option A and C have positive slope because the dots on graph goes up.

So we ignore A and C graph

B and D graphs have negative slope.

Given Correlation coefficient r is close to -0.5

In Graph B the dots are close to one another . It means the correlation coefficient r is close to - 1

Graph D shows a negative linear relationship with a correlation coefficient r close to =-0.5

A rational function has x = - 4 as a vertical asymptote. What term appears in factored form in the denominator of the function?

pantera1 [17]

Answer:

A.x+4

Step-by-step explanation:

We are given that a rational function which has a vertical asymptote at x=-4.

We have to find the term which appears in factored form in the denominator of the function.

We know that

To find the vertical asymptote of a rational function we will substitute the

denominator equal to zero.

Then, solve for x.

The value of x obtained are called vertical asymptotes.

By definition of vertical asymptote

x=-4

x+4=0

x+4 will be appears in factored form in the denominator of the function.

4y square + y - 45 when y=-5

kobusy [5.1K]

Given:

The expression is

$4y^2+y-45$

To find:

The value of the given expression when y=-5.

Solution:

We have,

$4y^2+y-45$

Putting y=-5, we get

$4(-5)^2+(-5)-45$

$=4(25)-5-45$

$=100-50$

$=50$

Therefore, the value of the given expression is 50 when y=-5.
