The graph of which of the following equations is a line parallel ot the graph of x-5y=8

Parallel lines are lines that have the same slope. The line of is parallel to the line of

Given that:

Make y the subject

Divide both sides by 5

A linear equation is represented as:

Where:

slope

So:

For two lines to be parallel to , they must have the same slope (m)

Of the given options

(a) x+5y=8   (b) 5x-y=8    (c) 2x+10y=8   (d) 2x-10y=8

Only  has the same slope as and the proof is as follows:

Make y the subject

Divide by -10

The slope (m) of the above line is:

The slope of the two lines are

Hence, is parallel to the line of

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242
