Anika [276]3 years ago

Answer:

The answers to the first question are A,C,D

The answer to the second question is YZ=16

Step-by-step explanation:

(1st Question)

Since <K and <M Are equal, and both <L's are equal, KL and ML are congruent (Answer choice) because of the ASA postulate.

You need to create the following equation to find the length of KN and MN 7x-4=5x+12

(Get the "x" variable to one side)

2x-4=12

(Isolate the variable)(Remove the 4)

2x=16

(Divide the 2 by itself to remove it from the x, remember to divide both sides by 2)

x=8 (Answer Choice)

Plug in the x value into each equation

KN= 7(8)-4

KN= 56-4

KN= 52

MN= 5(8)+12

MN= 40+12

MN= 52 (Answer Choice)

MN=KN

(Second Question)

Since XWY(20) is half of XWZ(40), ZWY also equals 20.

This now proves the triangle is congruent by the AAS postulate.

Since the triangles are congruent, if XY = 16, YZ also equals 16.

A given line has the equation 2x + 12y = −1. What is the equation, in slope-intercept form, of the line that is perpendicular to
VikaD [51]

Answer:

y = 6x + 9

Step-by-step explanation:

The equation of a line in slope- interceot form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2x + 12y = - 1 into this form

Subtract 2x from both sides

12y = - 2x - 1 ( divide all terms by 12 )

y = - \frac{1}{6} x - \frac{1}{12} ← in slope- intercept form

with slope m = - \frac{1}{6}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{1}{6} } = 6

Note the line passes through (0, 9) on the y- axis ⇒ c = 9

y = 6x + 9 ← equation of perpendicular line

Please help me with this thanks
Kryger [21]

Step-by-step explanation:

B = area of the base

= 9×4 = 36 square inches

P= perimeter of the base

= 2(9+4)

=2×13= 26 inches

H =distance between the bases

= 16 inches

SA= 2B+PH

= 2(36)+ 26× 16

= 72+416 = 488 square inches

Write the equation of the line that passes through the point (3,5) and is perpendicular to the line y=3.
3241004551 [841]

Answer:

x = 3

Step-by-step explanation:

y = 3 is the equation of a horizontal line parallel to the x- axis.

A line perpendicular to it must therefore be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (3, 5) with x- coordinate 3 , thus

x = 3 ← equation of perpendicular line
