Greetings and Happy Holidays!

<span>1) Perpendicular to </span>-x+5y=14
In order for lines to be perpendicular, their slopes must be negative reciprocals.
Example of slopes with negative reciprocals: 5 and \frac{-1}{5}

First, rearrange the equation into slope y-intercept form:
-x+5y=14

5y=x+14

\frac{5y}{5}=\frac{x+14}{5}

y=\frac{1}{5}x+\frac{14}{5}

The slope of the equation is: \frac{1}{5}

The negative reciprocal formula: (m_{1})(m_{2})=-1

Solve for the negative reciprocal: 
\frac{1}{5}m_{2}=-1

Divide both sides by \frac{1}{5}
\frac{\frac{1}{5}m_{2} }{ \frac{1}{5}} = \frac{-1}{ \frac{1}{5}}

m_{2}=(-1)(\frac{5}{1})

m_{2}=(\frac{-5}{1})

m_{2}=-5

The slope of the new line is: -5

2) Passes through (-5,-2)

Create
an equation with the slope discovered in slope y-intercept form.
y=-5x+b

Input
the point the line passes through.
(-2)=-5(-5)+b

Solve
for b (the y-intercept).
-2=-5(-5)+b

Multiply.
-2=25+b

Add
-25 to both sides.
(-2)+(-25)=b

-27=b

The y-intercept is equal to -27

The Equation of the line is:
y=-5x-27

I hope this helped!

The question states that both parts of Noshi's desk were shaped like trapezoids and both had a height of 3.

We know that the formula for area of a trapezoid is (a+b)/2 * h, where a and b are bases of the trapezoid and h is the height. Note: This is like any other form of trying to find the area, because we are doing base times height, however, we need to divide the sum of the bases by 2 to find the average base length.

Let's call the first trapezoid on the left Trapezoid A and the second slanted trapezoid Trapezoid B.

Area of Trapezoid A = (a+b)/2 * h = (5+8)/2 * 3 = 13/2 * 3 = 6.5 * 3 = 19.5 feet
Area of Trapezoid B = (a+b)/2 * h = (4+9)/2 * 3 = 13/2 * 3 = 6.5 * 3 = 19.5 feet

To find the area of Noshi's total desk, we simply need to add the areas of Trapezoid A and Trapezoid B together.

19.5 feet + 19.5 feet = 39 feet

Therefore, the area of Noshi's desk is 39 feet.

Hope this helps! :)

What is the solution of two thirds x=12
joja [24]
Hi there!

To solve this problem, we need to simplify. 

2/3x = 12

To isolate x, we should multiply both sides of the equation by the reciprocal of 2/3 to make x equal to a value:

Reciprocal of 2/3 = 3/2

x = 12 * 3/2
x = 18 

Hope this helps!

The perimeter of a parallelogram is 180 cm. One side exceeds the other by 10 cm. What are the lengths of adjacent sides of the p
Georgia [21]

Answer:

one side is 40 other is 50

Step-by-step explanation:

perimeter=180cm

let one side=length=x

Acc. to condition:

other side=width=x+10 (one side exceed other by 10)

perimeter= 2(length+width)

subtitue all values given above:

180=2(x+x+10)

180=2(2x+10)

2x+10=180/2

2x+10=90

2x=90-10

2x=80

x=40

now

lenght=x=40cm

width=x+10=40+10

width=50cm
