Answer:

y-1=3(x-2)

Step-by-step explanation:

The point-slope form of a line is

y-y_{1} =m(x-x_{1} )

where m denotes slope of line and (x_{1} ,y_{1} ) is a point on line.

From question statement,we observe that

m= 3 and (x_{1} ,y_{1} )=(2,1)

putting above values in point-slope form of line,we get

y-1=3(x-2) is point slope form of a line with slope 3 that contains the point (2,1).

Answer:

Point slope form:

The equation of line is given by: y-y_1=m(x-x_1)        .....[1]

where m is the slope and a line contains a point (x_1, y_1).

As per the given statement:

Slope(m) = 3

(x_1, y_1). = (2, 1)

Substitute these in [1] we have;

y-1=3(x-2)

therefore, the point slope form of a line with slope 3 that contains the point (2, 1) is; y-1=3(x-2)

In an examination a candidate has to secure 40%of the marks to pass if a candidate secure 190marks and fails by10marks the total
MaRussiya [10]

The total number of marks in the examination is <u>500 marks</u> when the passing percentage is 40%, and a candidate securing 190 marks, failed by 10 marks.

In the question, we are given that in an examination, a candidate has to secure 40 percent of the marks to pass.

We are asked the total number of marks in the examination if a candidate secured 190 marks and failed by 10 marks.

The marks secured by the candidate = 190 marks.

The marks which he failed by = 10 marks.

Thus, passing marks = 190 + 10 = 200 marks.

We assume the total marks to be x marks.

We are given that to pass, a candidate needs 40 percent of the total marks.

Thus, passing marks = 40% of x marks.

But, we calculated the passing marks to be 200 marks.

Thus, we get an equation,

40% of x = 200,

or, 40/100 * x = 200,

or, x = 200*100/40 = 500.

Thus, the total number of marks in the examination is <u>500 marks</u>, when the passing percentage is 40%, and a candidate securing 190 marks, failed by 10 marks.

Find the value of x in each case and give an explanation plzzz, thank youu :)
Serga [27]

Answer:

Step-by-step explanation:

the arrows from the picture tells us that TV is parallel to RS

since TS is a transversal that cuts the 2 parallel lines TV and RS than ∠S =x

(alternate interior angles)

sum of angles in a Δ is 180° so x+x+2x = 180°, 4x =180°, x= 45°

2x = 45*2 = 90°
