6 0

Answer:

3

Step-by-step explanation:

Slope is given by

\frac{y2 - y1}{x2 - x1}

where y2 = -1, y1 = -7, x2 = -1, x2 = -3

\frac{ - 1 - ( - 7)}{ - 1 - ( - 3)}  =  \frac{ - 1 + 7}{ - 1 + 3}

=   \frac{6}{2}  = 3

A rectangle has a a perimeter of 72 ft. The length and width are scaled by a factor 3.5.
Ivanshal [37]
Perimeter of a rectangle:
P = 2 L + 2 W,  P = 72 ft
P ( new ) = 2* 3.5 L + 2 * 3.5 W = 3.5 * ( 2 L + 2 W ) = 3.5 P
P ( new ) = 3.5 * 72 = 252 ft
Answer:
The perimeter of the new rectangle is 252 ft.

What coordinate do lines 2/3x+1/6y=2/3 and 4x+y=4 meet?
VMariaS [17]

Answer:

The coordinates of the lines when both lines meets at point is ( 0, 0 )

Step-by-step explanation:

Given as :

The two lines are

\frac{2}{3}x + \frac{1}{6}y = \frac{2}{3}

And 4 x + y = 4

The coordinate of the lines are obtained when the two lines intersect

Let the coordinate of intersection points are ( x , y )

Now , The first lines as

\frac{2}{3}x + \frac{1}{6}y = \frac{2}{3}

Or, Taking LCM we get ,

\frac{4x + y}{6} = \frac{2}{3}

Cross multiplication both sides

Or, 3 × ( 4 x + y ) = 2 × 6

Or,  3 × 4 x +  3 × y = 12

Or, 12 x + 3 y = 12          ...........A

Other line is 4 x + y = 4

i.e 3 × ( 4 x + y ) = 3 × 4

or, 12 x + 3 y = 12          .........B

Solving both the line equations

(12 x + 3 y ) - ( 12 x + 3 y ) = 12 - 12

I.e x = 0  and  y = 0

So coordinates are ( x , y )  =  ( 0 , 0 )

Hence The coordinates of the lines when both lines meets at point is ( 0, 0 ) Answer
