Answer:

a = 8 2/3.

Step-by-step explanation:

The y coordinate of the point is 5, andthe x coordinate is a so substituting for these in the given equation:

3a - 4(5) = 6

3a  - 20 = 6

3a = 26

a = 26/3

= 8 2/3

\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}

here , we've been given a point with coordinates ( a , 5 ) and an equation ( 3x - 4y = 6 ).

  • <u>To </u><u>determine </u> - the value of a

Coordinate geometry deals with parameters related to points over cartesian plane , where a points , say G , has two coordinates x and y.

the coordinates are written as ( x , y ) , where x is the x coordinate or abcissa and y is the y coordinate or ordinate.

for getting the solution to the question asked , let us think of <u>x </u><u>as </u><u>a </u> and <u>y </u><u>as </u><u>5</u><u>.</u>

Now ,

substituting the values of x and y in the equation ,

3x - 4y = 6 \\ \implies \: 3(a) - 4(5) = 6 \\ \implies \: 3a - 2 = 6 \\ \implies \: 3a = 6 + 20 \\ \implies \: 3a = 26 \\ \implies \: a =  \frac{26}{3}

let's once check , if we've arrived at the correct result or no.

This can be done , by putting value of x as \frac{26}{3}\\ which is the value of a.

So ,

3x - 4y = 6 \\  \\ \implies \: \cancel3 (\frac{26}{\cancel3} ) - 4(5) =  6\\  \\ \implies26 - 20 = 6 \\  \\ \implies \: 6 = 6

hence , verified !

Therefore ,

\bold\red{a =  \frac{26}{3} }\\

hope helpful :D

A square is made up of an L-shaped region and three transformations of the region. If the perimeter of the square is 40 units, w
Mila [183]

Answer:

20 units

Step-by-step explanation:

This implies that the square can be divided into four equal L-shaped regions. These regions with respect to transformation forms a square.

Perimeter of the square is 40 units. Since a square has equal length of sides, thus each side of the square is 10 units.

Thus, each L-shape region has dimensions; 8 units, 5 units, 5 units and 2 units.

Perimeter of each L-shape region = the addition of the length of each side of the shape

Perimeter of each L-shape region = 8 + 5 + 5 + 2

                                                         = 20 units
