Two events are mutually exclusive if they cannot occur at the same time.

For what value of x will the line passing through the points A(x+14, 5) and B(2−3x, 8) be vertical?
trapecia [35]

Answer:

x=-3

Step-by-step explanation:

we know that

The slope of a vertical line is undefined

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

A(x+14, 5) and B(2−3x, 8)

substitute

m=\frac{8-5}{(2-3x)-(x+14)}

m=\frac{3}{2-3x-x-14}

m=\frac{3}{-4x-12}

so

If the slope is undefined

then

The denominator must be equal to zero

-4x-12=0

solve for x

4x=-12\\x=-3

Evaluate angles d and e, giving reason for your answer​
Jobisdone [24]

Answer:

Ok so we know that the angle on top is 110 since the angle above is the same.

we also know that all the angle of the triangle will add up to 180 so

D+(180-E)+110=180

we also know that d and the angle directly across are the same so

180-110=70

70divide by 2 equals 35

now we subtratch 35 from 180 to get 145

E=145

D=35

Your Welcome
