Elan Coil [88]

For this one it's really simple. Just do 90-(-2). It may look confusing right now, but it's really easy. All you need to know is that a negative and a negative cancel out to form a positive. So it's actually 90+2. 92 is the difference.

A man bought certain number of litches

Arlecino [84]

Answer: The loss is 4%

Step-by-step explanation:

Lets call litches that are 20 pcs per Rs 100 - litches A

that are 30 pcs per Rs 100- litches B

So a man can buy 2 pcs A per Rs 10

and 3 pcs B per Rs 10

6x pcs A per Rs 30x

and 6x pcs B per Rs 20x

Now he gonna sell the 12x litches for y Rs

Lets find y from the proportion

12x cost y

25 cost 100

y/12=100/25

y=48 Rs

So the man bought 6x A + 6x B for 20x+30x=50 Rs

And then he sold them for 48 Rs

Obviously the man gonna loose the money.

Lets find the losses in %

(50-48)/50*100=200/50=4%

The loss is 4%

(02.02 MC) Use the graph to fill in the blank with the correct number.

saveliy_v [14]

Answer:

The answer is "2"

Step-by-step explanation:

When we check the points where the x is -2

by calculating the "y-value":

It is 2, right?

it implies that $f(-2)=2$

that's why the final answer is "2"

Where do (3/2,-7) and (-4,5) intercept

Vinil7 [7]

Answer:

The intercept of the given points is - $\frac{41}{11}$

Step-by-step explanation:

Given points as :

( $x_1$ , $y_1$ ) = ( $\frac{3}{2}$ , - 7 )

( $x_2$ , $y_2$ ) = ( - 4 , 5 )

Now, slope of line using given points can be written as :

Slope = m = $\dfrac{y_2 - y_1}{x_2 - x_1}$

or. m = $\dfrac{5 - ( - 7 )}{( - 4 ) - [tex]\frac{3}{2}$ }[/tex]

or, m = $\dfrac{12}{( - 4 ) - [tex]\frac{3}{2}$ }[/tex]

or, m = $\frac{12}{\frac{- 8 - 3}{2}}$

Or, m = $\frac{12}{\frac{- 11}{2}}$

∴ m = $\frac{-24}{11}$

So, The slope of the line using points = m = $\frac{-24}{11}$

now, equation of line in slope intercept form can be written as

y - $y_2$ = m × ( x - $x_2$ )

or, y - 5 = $\frac{-24}{11}$ × ( x - ( - 4 ) )

or, y - 5 = $\frac{-24}{11}$ × ( x + 4 )

Or, 11 × ( y - 5 ) = - 24 × ( x + 4 )

Or, 11 y - 55 = - 24 x - 96

Or, 11 y = - 24 x - 96 + 55

Or, 11 y = - 24 x - 41

∴ y = $\frac{-24}{11}$ x - $\frac{41}{11}$

Now, comparing with slope intercept equation

I.e y = m x + c , where c is the intercept

So, The intercept of points is - $\frac{41}{11}$

Hence The intercept of the given points is - $\frac{41}{11}$ Answer
