Answer: $(y-1)=9(x-6)$

Step-by-step explanation:

If a line is passing through the point (a,b) and has a slope m, then the equation of the line in point-slope form is given by :-

$(y-b)=m(x-a)$

Given: A line that includes the point (6, 1) has a slope of 9.

The equation of line in point-slope form: $(y-1)=9(x-6)$

Hence, the required equation in point slope form: $(y-1)=9(x-6)$

If the amount of vat paid by a customer while buyong a bag at 13℅ vat rate rs 143 ,find the cost of bag without vat

Darya [45]

Step-by-step explanation:

vat %=13%

vat=143

vat = vat% of sp (i.e sp without vat)

143 = 13/ 100 of sp

143*100=13sp

14300/13 = sp

sp=4766.67

therefore the cost of bag without vat is rs.4766.67

Marquise has 200200200 meters of fencing to build a rectangular garden.

adoni [48]

Hence the maximum possible area is 2500 square meteres

Given the area of the rectangular garden expressed as;

$A(x)=-x^2+100x\\$

The maximum area occurs when dA(x)/dx = 0

$\frac{dA(x)}{dx} = -2x + 100\\0= -2x + 100\\ 2x = 100\\x = \frac{100}{2}\\x = 50$

Next is to get the maximum area possible. Substitute x = 50 into the original function as shown;

$A(50)= -50^2 + 100(50)\\A(50) = -2500+5000\\A(50) = 2500$

Hence the maximum possible area is 2500 square meters

You are playing a game of Scrabble and have the 5 A tiles, 3 E tiles, 1 Z tile, 2 M tiles, 3 L tiles, and 1 Y tile to choose fro

BigorU [14]

When calculating probability, the easiest thing to do is first count how many things there are to choose from.

5 + 3 + 1 + 2 + 3 + 1 = 15 Also, there are 3 E tiles, and 1 Y tile. 3 + 1 = 4

The probability of you drawing a E or Y tile is 4 / 15
