first function 2nd function

slope =(y2-y1)/(x2-x1) slope =(y2-y1)/(x2-x1)

=(14-2)/(3-0) m = (-3--12/(3-0)

12/3 m=(-3+12)/3

4 m =9/3 =3

y = 4x+2 y = 3x+-12

set these two equations equal

4x+2 = 3x-12

subtract 3x

x+2 = -12

subtract 2 from each side

x = -14

y = 3x-12

y =3*(-14)-12

y = -42-12

y = -54

1. A parallelogram is a four sided figure that has two pairs of parallel, opposite sides. Parallelogram ABCD is

sveta [45]

Answer:

The reason is that the since the segment AB and the new line passing through A are both parallel to the segment CD and all points on the new line and the segment AB are the same perpendicular distance from CD and the segment AB and the new line which follow the same direction share a common point, A, then the line drawn must fall on AB

Step-by-step explanation:

The given information are;

The shape of the quadrilateral ABCD = A parallelogram

The direction of the line to be drawn = Parallel to CD

A point on the line to be drawn = Point A

Therefore, given that ABCD is a parallelogram, we have;

Segment AB is parallel to segment CD

All points on AB are equidistant from all points on CD

The perpendicular distance of point A from the lime CD = The perpendicular distance of point B from the lime CD

The line to be drawn is also parallel to CD with point A located on the line, therefore, given that the length of a line is infinite, and all points on two parallel lines have equal perpendicular distance from the each other, the point B on the segment AB which has the same perpendicular distance as the point A from the segment CD will be located on the new line passing drawn passing through A and parallel to the segment CD then the new line drawn must coincide with the segment AB.

Lance has 3 time as many pencils as Nick, and they have 84 pencils together. How many pencils does each of them have?

Rufina [12.5K]

Answer:

21 pencils for Nick and 63 pencils for Lance

Step-by-step explanation:

Lance is said to have 3 times the pencils Nick has.
Let's keep the number of pencils Nick has as x.
If Nick has x pencils that means Lance has 3x pencils.
The total number of pencils present is 84.

Now let's make an equation out of the information above:

3x + x = 84

Now solve for x.

3x + x = 84

4x = 84

x = 84/4

x = 21

So Nick has 21 pencils

Now for Lance:

3 * (21) = 63

So Lance has 63 pencils

63 + 21 = 84 pencils

SVETLANKA909090 [29]

Answer:

Part A: 12.5 cm

Part B: 0.8 km

Step-by-step explanation:

Map scale problems can be solved with proportions.

Part A

5 cm / 2 km = x cm / 5 km

5/2 = x/5

2x = 25

x = 12.5

Answer: 12.5 cm

Part B

5 cm / 2 km = 2 cm / x km

5/2 = 2/x

5x = 4

x = 4/5

x = 0.8

Answer: 0.8 km
