Find any points of discontinuity for y = 5x+6/x2+6x+9

x = -3 is the point of discontinuity.

Hence, option B is correct.

Step-by-step explanation:

Given the expression

In order to determine the discontinuity, the denominator must be 0.

so let us solve the denominator to get the values of x

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

Subtract 3 from both sides

Therefore, x = -3 is the point of discontinuity.

Hence, option B is correct.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
