Answer:

4 or 4/1 (both the same thing just with plotting point writing 4/1 is easier for me so I know to go up 4 over 1 :) )

Step-by-step explanation:

Parallel lines have the same slope, so both lines will have the same slope. Use line 1’s points to find the slope with the formula

(y1-y2)/(x1-x2)

(5-1)/(-2-(-3)

4/1=4

Answer:

Answer is 4 .

Step-by-step explanation:

As parallel lines have same slopes..

Therefore,cordinate y1-y2 /x1-x2=Slope of L2

5-1/(-2-(-3))

=4/1

=4 ,Slope of line l2

Write the equation of the line that has a slope of -5 and a y intercept of 7
Elza [17]

Answer:

y = -5x +7

Step-by-step explanation:

slope intercept form of the equation is

y= mx+b

where m is the slope and b is the y intercept

The position of an open-water swimmer is shown in the graph. The shortest route to the shoreline is one that is perpendicular to
Stolb23 [73]

Answer:

Step-by-step explanation:

To define the perpendicular line we need to first know the slope of the reference line graphed.

m=(y2-y1)/(x2-x1) we have points (0,5) and (2,1)

m=(1-5)/(2-0)

m=-4/2

m=-2

For lines to be perpendicular their slopes must satisfy

m1m2=-1, we have a line with a slope of -2 so

-2m=-1

m=1/2, so our perpendicular line is so far

y=x/2+b, it must have point (3,2) so we can solve for b

2=3/2+b

b=1/2, so the swimmer will travel along the line

y=x/2+1/2

Find the coordinates of C' after a reflection across the line
iragen [17]
<h3>Answer:  (4,2)</h3>

==============================================================

Explanation:

C is at (0,0). Ignore the other points.

Reflecting over y = 1 lands the point on (0,2) because we move 1 unit up to arrive at the line of reflection, and then we keep going one more unit (same direction) to complete the full reflection transformation. I'll call this point P.

Then we reflect point P over the line x = 2 to arrive at the location Q = (4,2). Note how we moved 2 units to the right to get to the line of reflection, and then keep moving the same direction 2 more units, then we have applied the operation of "reflect over the line x = 2"

So we have started at C = (0,0), moved to P = (0,2) and then finally arrived at the destination Q = (4,2). This is the location of C' as well.

All of this is shown in the diagram below.

Solve the equation negative 3X +9 equals three(2x+3) + 3(x-4) + 1
timofeeve [1]

Answer:

1

Step-by-step explanation:

-3x+9=3(2x+3)+3(x-4)+1

Distributive property in the parenthesis

-3x+9=6x+9+3x-12+1

Combine Like Terms

-3x+9=9x-2

Get the x’s on one side

-3x+9=9x-2

+3.  +2    +3. +2

11=11x

Divide by 11 on both sides

11/11=1

skad [1K]
Total number of parts:
2+3=5.

Each part is:
20 cookies/ 5 parts= 4 cookies/part.

Number of chocolate cookies is:
4 cookies/part* 2 parts= 8 cookies.

Number of sugar cookies is:
4 cookies/part* 3 parts= 12 cookies.

There are 8 chocolate cookies and 12 sugar cookies~
