Answer:

The quadrilateral ABCD is a square.

Step-by-step explanation:

According to the statement, AB, BC, CD and DA are the sides of the quadrilateral, whereas DB and AC are its diagonals. If we know that x = 7, AB = 4\cdot x - 2, BC = 2\cdot x + 12, DC = 3\cdot x +5, AD = 6\cdot x -16, AC = 4\cdot x + 12 and DB = 8\cdot x -10, the lengths of each line segment are respectively:

Sides

AB = 4\cdot (7) -2

AB = 26

BC = 2\cdot (7) +12

BC = 26

DC = 3\cdot (7) +5

DC = 26

AD = 6\cdot (7) -16

AD = 26

Diagonals

AC = 4\cdot (7) +12

AC = 40

DB = 8\cdot (7) - 10

DB = 40

This information indicates that this quadrilateral is a square because of these characteristics:

1) All sides have the same length.

2) The ratio of any diagonal to any side is \sqrt{2}.

-2.2 + 0.3z= 3 -0.5z -0.8z<br><br> what does z equal
sineoko [7]
Add 2.2 to each side so 0.3z = 5.2 - 0.5z -0.8z
add 0.5z to each side so 0.8z = 5.2 - 0.8z
add 0.8z to each side so 1.4z = 5.2
divide each side by 1.4 so z = 3.71428571

What is the equation of the graph
balandron [24]

Answer:

y=6^x-2

Step-by-step explanation:

Start with the parent function, a^x. The graph looks like it has been translated b units down, so our function is a^x+b. Now at x=0, y=-2. So b=-2. Next at x=1, y=3. 3=a^(1)-2, a=6. y=6^x-2 is the equation
