Answer:

X=-1, y=4

Step-by-step explanation:

y = x + 4 \\ x + 2y = 8 \\  =  =  =  =  =  =  =  =  =  =  =  = \\ y - x = 4 \\ x + 2y = 8

by using eliminating property

3y = 12 \\ y = \frac{12}{3}    = 4

by substitution

X=-1

Which term BEST describes the quadrilateral formed when line segments connect points A, B, C, and D?
NeX [460]

Answer:

The quadrilateral formed is a trapezoid

Step-by-step explanation:

In this case, it is necessary to know what points A, B, C, and D.

If the points are equal to the following coordinate points

A (-2, 1)

B (2, 1)

C (3, -2)

D (-3, -2)

As shown in the image the answer would be a trapezoid.

________________________________

The figure cannot be a square, a rhombus or a rectangle since by definition these are:

A square has all sides of equal length and all its right angles.

A rhombus is a parallelogram that has all sides of equal length and all its angles different from right angles.

A rectangle is a parallelogram that has all its right angles.

The figure that we obtain is neither a parallelogram nor does it have all its right angles.

KIM [24]

It is given in the problem that

Liam buys a motorcycle for $2,900

Its value depreciates annually at a rate of 12%=0.12

At the end of t years, it has a value of less than $2,000

The exponential equation modeling this situation can be written as below

2900(1-0.12)^t

The inequality representing its value less than $2,000 can be written as below

2900(1-0.12)^t
