What percent of discount should be given in a doll costing Rs 180
wolverine [178]

Answer:

11.11%

Step-by-step explanation:

So the question is:

$180 * (x)% = $y

Therefore $180 - $y = $160

Now:

180 - 160 = 20

Therefore; $20 is the discount

Now per cent of discount:

20/180 * 100 = 11.111111111111111111111%

therefore: per cent of discount is 11.11% (rounded to two decimal place)

What is the equation of a line passing through the points (-3,<br> -2) and (2, 0)?
Lostsunrise [7]

Answer:

y=0.400x+-0.800

Step-by-step explanation:

Given the following question:

point A = (-3, -2)
point B = (2, 0)

To write the equation of the line that passes through two points we have to write the points in slope intercept form.

Formula for slope intercept:

y=mx+b

M is equal to the slope of the two points, so first we need to fine the slope of the two points.

(-3,-2)=(x1,y1)
(2,0)=(x2,y2)

m=\frac{y2-y1}{x2-x1}
m=\frac{0--2}{2--3} =\frac{2}{5}
m=\frac{2}{5} =0.400

y=mx+b
y=-2
m=0.400
x=-3
-2=0.400(-3)+b
0.400\times-3=-1.20
-2+1.2=-0.800
b=-0.800

y=0.400x+-0.800

Hope this helps.

vagabundo [1.1K]

f(x)= -1/2x-7 (better expressed as   f(x) = (-1/2)x - 7  )   has a negative slope, so as x increases, y decreases.  Answer D is correct.
