Answer:

Both a square and a rectangle may have their four angles at 90°, have parallel opposite sides with the same length, and have their diagonals equal in length, but only a square has four sides of equal length.

AB is dilated by a scale factor of 3 to form AB . Point O is the center of dilation, and point O lies on AB . If the slope of AB

avanturin [10]

<h2>Answer:</h2>

Option: D is the correct answer.

D. The slope of is 3, and passes through O.

<h2>Step-by-step explanation:</h2>

It is given that:

AB is dilated by a scale factor of 3 to form AB .

Also, the line AB pass through the origin.

So, if AB pass through (0,0) and some point (x,y) then the slope of line AB is:

$Slope=\dfrac{y-0}{x-0}\\\\i.e.\\\\Slope=\dfrac{y}{x}=3$

( Since, it is given the slope of AB is 3 )

Now , if AB is dilated to A'B' by a scale factor of 3 then

(0,0) → (0,0)

and

(x,y) → (3x,3y)

i.e. (0,0) and (3x,3y) will lie on A'B'.

Hence, the slope of line A'B' is given by:

$Slope=\dfrac{3y-0}{3x-0}\\\\i.e.\\\\Slope=\dfrac{3y}{3x}\\\\i.e.\\\\Slope=\dfrac{y}{x}=3$

Hence, both have the same slope.

The answer is : Option: D

A coach purchases 47 hats for his players and their families at a total cost of $302. The cost of a small hat is $5.50. A medium

blagie [28]

Answer:

d. 23

Step-by-step explanation:

x: small hat

y: medium hat

z: large hat

We now write the system of equations:

x + y + z = 47

5.50x + 6y + 7z = 302

-3x + y = 0

We can write the system in matrix form as:

Ax = b

Where,

A = [1 1 1; 5.50 6 7; -3 1 0]

b = [47; 302; 0]

x = [x; y ; z]

Solving the system we have:

x = 6

y = 18

z = 23
