Answer:

y=-\frac{2}{5}x-3

Step-by-step explanation:

First, you must find the midpoint of the segment, the formula for which is (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}). This gives you (-5,-1) as the midpoint. This is the point at which the segment will be bisected.

Next, since we are finding a perpendicular bisector, we must determine what slope is perpendicular to that of the existing segment. To determine the segment's slope, we use the slope formula \frac{y_{2}-y_{1} }{x_{2}-x_{1}}, which gives us a slope of \frac{5}{2}.

Perpendicular lines have opposite and reciprocal slopes. The opposite reciprocal of \frac{5}{2} is -\frac{2}{5}.

We now know that the perpendicular travels through the point (-5,-1) and has a slope of -\frac{2}{5}.

Solve for b in y=mx+b.

y=mx+b\\-1=-\frac{2}{5}(-5)+b\\-1=2+b\\-3=b\\b=-3

Therefore, the equation of the perpendicular bisector is  y=-\frac{2}{5}x-3.

A half-acre building lot is five times as long as it is wide. What are its dimensions?
Gnoma [55]

we know that

A half-acre is equal to----------> 2,023.43\ m^{2}

Let

x---------> the length side of the building lot

y--------> the width side of the building lot

A------> Area of the building lot

x=5y-------> equation 1

A=2,023.43\ m^{2}

A=x*y

2,023.43=x*y --------> equation 2

substitute equation 1 in equation 2

2,023.43=[5y]*y

5y^{2}= 2,023.43\\y^{2}= 404.686\\y= 20.11\ m

<u>Find the value of x</u>

x=5y---> x=5*20.11--> x=100.55 m

therefore

<u>the answer is</u>

the dimensions of the building lot are 100.55 m* 20.11 m

Johnny and Cage are working together to mold figurines for a craft fair. They already have 8 figurines which were left from the
alukav5142 [94]

Answer:

See Explanation

Step-by-step explanation:

Given

Initial = 8

Increment = 3 (every hour)

Required

Explain why it is linear

First, we need to determine the equation that represents the scenario

Let x be the number of hours worked and y be the number of figurines at x hours.

The equation is determined as follows:

y = Initial\ Figurines + Increment * x

This gives:

y = 8 + 3 * x

y = 8 + 3x

Reorder

y = 3x + 8

A linear equation is of the form

y = mx + b

By comparison,

y = mx + b is equivalent to y = 3x + 8

<em>Hence, we can conclude that the situation is linear</em>
