What coordinate do lines 2/3x+1/6y=2/3 and 4x+y=4 meet?

VMariaS [17]

Answer:

The coordinates of the lines when both lines meets at point is ( 0, 0 )

Step-by-step explanation:

Given as :

The two lines are

$\frac{2}{3}$ x + $\frac{1}{6}$ y = $\frac{2}{3}$

And 4 x + y = 4

The coordinate of the lines are obtained when the two lines intersect

Let the coordinate of intersection points are ( x , y )

Now , The first lines as

$\frac{2}{3}$ x + $\frac{1}{6}$ y = $\frac{2}{3}$

Or, Taking LCM we get ,

$\frac{4x + y}{6}$ = $\frac{2}{3}$

Cross multiplication both sides

Or, 3 × ( 4 x + y ) = 2 × 6

Or, 3 × 4 x + 3 × y = 12

Or, 12 x + 3 y = 12 ...........A

Other line is 4 x + y = 4

i.e 3 × ( 4 x + y ) = 3 × 4

or, 12 x + 3 y = 12 .........B

Solving both the line equations

(12 x + 3 y ) - ( 12 x + 3 y ) = 12 - 12

I.e x = 0 and y = 0

So coordinates are ( x , y ) = ( 0 , 0 )

Hence The coordinates of the lines when both lines meets at point is ( 0, 0 ) Answer

PLEASE HELP..... I WILL GIVE BRAINLIEST!!

Yakvenalex [24]

For the first part:

Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:

$12+12+12=3(12)$

With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:

$19+19=2(19)$

So, her total is:

$3(12)+2(19)$

If you subtract 3 from the total, then the expression is:

$3(12)+2(19)-3=36+38-3=71$

For the second part:

If she's paying 3 less for each shirt, then the cost of 3 shirts will become:

$(12-3)+(12-3)+(12-3)=3(12-3)$

In the same fashion, for the two jeans:

$(19-3)+(19-3)=2(19-3)$

So the expression for the total cost is:

$3(12-3)+2(19-3)=36-9+38-6=59$

For number three:

The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.

For number four:

If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).

So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.

Find the area of the shaded region.

taurus [48]

Answer:

$426.96 \: {km}^{2}$

Step-by-step explanation:

Area of the shaded region = Area of triangle with base 40 km and height 27 km - Area of circle with radius (12/2) 6 km.

$= \frac{1}{2} \times 40 \times 27 - 3.14 \times {(6)}^{2} \\ \\ = 20 \times 27 - 3.14 \times 36 \\ \\ = 540 - 113.04 \\ \\ = 426.96 \: {km}^{2}$
