The missing vertices of the pararllelogram is D(- 4, 0).

What is a parallelogram?

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

We know the diagonals of a parallelogram bisect each other.

Given, Three of the four vertices (corners) of a parallelogram are A(-2,7), B(3,7), and C(2,5) and assuming the fourth vertices is D(x, y).

∴ The midpoint of BD is equal to the midpoint of AC.

Midpoint of a line segment joining the point (x₁, y₁) and (x₂, y₂) is

(x₁ + x₂)/2, (y₁ + y₂)/2.

So, (3 + x)/2, (7 + y)/2 = (-2 + 3)/2, (7 + 7)/2.

(3 + x)/2 = -1/2.

3 + x = - 1.

x = - 4 And,

(7 + y)/2 = 14/2.

7 + y = 7.

y = 0.

So, D(- 4, 0).

A company offers customers two plans for Internet service.

Plan A: $30 for the modem and $5 per month for service.

Plan B: $20 for the modem and $10 per month for service.


Equations:

Plan A: _______________

Plan B: _______________


BONUS: After how many months will both plans equal the same? _______________

Answers

Answer:

Step-by-step explanation:

lets say you are paying for a year

A- it would cost you $30 on the spot and another 60 for the year

A=30$60= $90

A-$30+($5*t)

B- it will cost you $20 on the spot then another 120 for the year

B-$20+($10*t)

B=$20+$120= $140

t= 12

plan A: 5x+30
plan B: 10x+20
bonus: the 2nd month

explanation for bonus:
5(2)+30
10+30
=40

10(2)+20
20+20
=40

the first month plan A would cost $35. plan b would cost $30 the first month. So, the earliest month both of them would cost the same price would be the second month.

Step-by-step explanation:

First, rearrange the equation.

w^2 + 4w - 60 = 0

Next, factor.

10-6=4, (-6)(10)=-60

(w+10)(w-6)=0

w=-10 or 6

There is no such this as negative length, so the answer must be 6.
