Find the equation of the line shown.

Answers

Given : A graph of linear equationis given to us.

To Find : The equation of the line .

Solution : Here we can see that the line passes through points ( 1 , 2 ) and ( 2 , 4). So , clearly here we can use Two - point form to find the equation of the line .

So , first point will be , ( 1 , 2 ) & second point will be ( 2 , 4 ) . So here ;

[tex]\sf x_1 = 1\: \& \:y_1 = 2[/tex][tex]\sf x_2 = 2\: \&\: y_2=4[/tex]

Now , the two point form formula is :

[tex]\Large\boxed{\red{\sf \purple{\mapsto} y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)}}[/tex]

[tex]\tt:\implies y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]

[tex]\tt:\implies y-2=\dfrac{4-2}{2-1}(x-1) [/tex]

[tex]\tt:\implies y-2 = \dfrac{2}{1}(x-1) [/tex]

[tex]\tt:\implies y-2=2(x-1)[/tex]

[tex]\tt:\implies y -2 = 2x - 2 [/tex]

[tex]\underline{\boxed{\purple{\tt\longmapsto 2x - y = 0}}}[/tex]

Wilson paints 40% of a bookcase in 20 minutes.

How much more time will it take him to finish the bookcase?

Answers

Answer:

30 minutes

Step-by-step explanation:

The percentage rises up by 40% every 20 minutes and if we divide that in half he paints 20% in 10 minutes. Wilson needs to paint 60% more of the bookcase. 40% plus 20% is 60%. So we just add 20 with 10 to get 30 minutes.

How do I write an equation in point-slope form for m=-3 (-2,-1) ?

Where
m

Substituting the slope and values from the point in the problem gives:

Answer:

y + 1 = -3(x + 2)

Step-by-step explanation:

Point-slope form is y - y1 = m(x - x1)

m= -3 (-2, -1)

Plug -3 in for the m in the equation, -2 in for x1, and -1 in for y1

y - (-1) = -3(x - (-2))

Subtracting negatives will make them positive

y + 1 = -3(x + 2)

This is the point-slope form, continuing to solve for y will give the y-intercept form.

Y-intercept Form:

y = -3x - 7

All perfect squares are divisible by 2.
A.) true
B.) False, counterexample of 16
C.) False, counterexample of 15
D.) False, counterexample of 25

Answers

Answer:

the correct answer is C

Step-by-step explanation:

because the square root of 15 is 3.8 and 3.8 isnt divisible by 2

D. False, counter example of 25.
The reason for that is because A is not true, B is not a counterexample, C is not a square, so D is the answer.

When an article is sold at a discount of 10 %, a profit of Rs 8 is earned. If the same
article is sold without allowing a discount, there will be a profit of Rs 20. Find the cost price of the article.

Answers

Answer:

Market Price = MP

Cost Price = CP

P1 = (MP - 10%) - CP = Rs8

- CP = Rs8 - 0.90% MP

CP = 0.90 MP - Rs8

P2 = MP - CP = Rs20

- CP = Rs20 -MP

CP = MP - Rs20

0.90 MP - Rs8 = MP - Rs20

- 0.10% MP = - Rs12

0.10% MP = Rs 12

MP = Rs120p

CP = MP - Rs20 = Rs120 - Rs20 = Rs100.

The cost price of the item is Rs100.

Data Set A has a mean of 215 and a standard deviation of 35. Data Set B has a mean of 400 and a standard deviation of 12.
Which data set is more spread out?

Answers

Answer:

Data set A

Step-by-step explanation:

Data set A is the one that is more spread out.

The mean is the same as the average of a given sample. It is usually a measure of the central tendency of a data set.

Standard deviation is a measure of the spread of a given set of data.

The lower the value of the standard deviation, the more clustered around the mean a data is. Data is spread out if it has a higher value of standard deviation.

Since data set A has a standard deviation of 35, it the most spread out.

But as he forged along he saw to his great astonishment that all the lights were in one enormous buildinga lofty structure with pointed towers plunging upward into the gloom. His eyes made out the shadowy outlines of a palatial chateau; it was set on a high bluff, and on three sides of it cliffs dived down to where the sea licked greedy lips in the shadows.
