Please help i dont know how to do either question

Step-by-step explanation:

A(2 , 5)  ; B(2 , -4)

X coordinate of point A and x- coordinate of point B is 2. So the  Line AB is parallel to y-axis.

The line that is perpendicular to line AB is parallel to X- axis.

So the Slope of line perpendicular to line AB = 0

14) y = (-1/2)x + 5

Slope = -1/2

Parallel line have same slope.

Slope of the line parallel to the given line = -1/2

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
