Parallel to y=−3/4x, through (4, -1)
kolbaska11 [484]

Answer:

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

Step-by-step explanation:

The slope-intercept form is given by y=mx+c, where m is the slope and c is the y-intercept.

Slope of given line= -\frac{3}{4}

Parallel lines have the same slope. Thus, the slope of the line would also be -\frac{3}{4}.

y=-\frac{3}{4}x +c

The value of c can be found by substituting a pair of coordinates.

When x= 4, y= -1,

-1=-\frac{3}{4} (4)+c

-1= -3 +c

<em>Add 3 to both sides:</em>

c= -1 +3

c= 2

Thus, the equation of the line is \bf{y=-\frac{3}{4}x+2.

Ghella [55]

Answer:

hints to solve each. partial answer due to lack of time, hope it helps!

Step-by-step explanation:

1)

a) solve ():

5 \sqrt{3} + 7 \sqrt{3} - 9 \sqrt{3} - 6 \sqrt{3} + 12 \sqrt{3} - 10 \sqrt{3} =

\sqrt{3} . (5 +7-9-6+12-10)

b) use \sqrt{6\\} = \sqrt{3\\}\\\\\sqrt{2\\}\\\\

c) use \sqrt{20\\} = \sqrt{4\\}\\\\\sqrt{5\\}\\\\ = 2\sqrt{5\\}\\\\

use \sqrt{8\\} = \sqrt{4\\}\\\\\sqrt{2\\}\\\\ = 2\sqrt{2\\}\\\\

2)

a) use \sqrt{30\\} = \sqrt{6}\sqrt{5}

use \sqrt{30\\} = \sqrt{6}\sqrt{4} = 2\sqrt{6}
