Solve for x. 2=4x-6​

Mathematics
1 answer:
77julia77 [94]3 years ago
8 0

Answer:

x = 2

Step-by-step explanation:

Rewrite the equation as 4x - 6 = 2

Move all terms not containing x to the right side of the equation:

Add 6 to both sides of the equation.

4x = 2 + 6

Add 2 and 6.

4x = 8

Divide each term by 4 and simplify.

Divide each term in 4x = 8 by 4.

\frac{4x}{4} =\frac{8}{4}

Reduce the expression by cancelling the common factors.

x=\frac{8}{4}

Divide 8 by 4.

x = 2

Line AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (−1, 4). Lines AB and CD are
vlada-n [284]

Answer  

Option (A) is correct .

Reason

The formula for the slope.

Slope = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

As given

Line AB contains (0, 4) and (1, 6) .

put in the slope formula

Slope = \frac{6 - 4}{1 - 0}

Slope = \frac{2}{1}

Slope of the AB is 2.

As given

Line CD contains points (2, 10) and (−1, 4).

put in the slope formula

Slope = \frac{4 - 10}{-1 -2}

Slope = \frac{-6}{-3}

Slope = 2

Slope of the CD is 2.

As the slope of the  AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (−1, 4) is 2 .

Therefore the option (A) is correct i.e the lines are parallel because the slopes are the same.

How many even k-digit numbers can be constructed out of the digits 3, 4, 5, 6, and 7?
nordsb [41]

Answer:

A. 1562 numbers , B. 130 numbers

Step-by-step explanation:

<u>A)</u> Using same digit again

1 digit nos = 2 ( ie 4 , 6 )

2 digit nos = 5  (ie any no) x 2 ( ie 4 ,6 )

Similarly

3 digit nos = 5 x 5 x 2

4 digit nos = 5 x 5 x 5 x 2

5 digit nos = 5 x 5 x 5 x 5 x 2

Adding all 5 equations

Total = 2 + 10 + 50 + 250 + 1250  = 1562

<u>B)</u> Cant use a digit more than once

1 digit nos = 2 ( ie 4 , 6 )

2 digit nos = 4 ( ie any no other than 4 or 6) x 2  ( ie 4 , 6 )

Similarly

3 digit nos = 4 x 3 x 2

4 digit nos = 4 x 3 x 2 x 2

5 digit nos = 4 x 3 x 2 x 1 x 2

Adding all five equations

Total = 2 + 8 + 24 + 48 + 48 = 130
