The easy answer: If, say, B is the zero matrix, i.e.

then

First you have to know the price of item.
EX: Say a candy car costs $1.50.
The candy bar was marked down 30%.
$1.50 x 30/100 = $.45
The item will decrease $.45.
$1.50 - $.45 = $1.05
Answer:
7
Step-by-step explanation:
There is a point of inflection at each point where the graph crosses the line y=2. There are 7 points of inflection shown.
__
A point of inflection is where the graph changes from being concave downward to concave upward, or vice versa. For a sine function, that is everywhere the function crosses its midline.
Let’s first find the angle y
Angle y = 180-(140+10)(angle sum property)
Angle y = 180-150
Angle y = 30 degrees
Angle x = 180- 110 ( linear pair )
Angle x = 70
Angle z = 180-(70+90)( angle sum property)
Angle z = 180-160
Angle z = 20
Circle Q is a translation of circle P, 6 units up and <span>Circle Q is a dilation of circle P with a scale factor of 7 are both correct answers.
Similar figures can result when a figure is translated (moved or slid) to a different position or when it remains the same shape but in a different size (dilation).</span>
