Answer:
The answer to your question is the last choice.
Step-by-step explanation:
The first column represents the x
The second column represents the y
The third column represents the z
The last column represents the independent term
The first line represents the first equation
The second line represents the second equation
The third line represents the last equation
From the previous information, we conclude that the answer is the last choice.
Given:
Two endpoints of a diameter of a circle:
P (-7, -10)
Q (3, 2)
a) To find the center of the circle, find the midpoint of the two points:
midpoint:
(x2 - x1 )/ 2 , (y2 - y1) / 2
x= (2 - (-7))/2 = 4.5
y= (3 - (-10))/2 = 6.5
Therefore, the center of the circle is at C(4.5, 6.5)
b) To find the radius of the circle, we need to find the distance between the two points and divide by 2.
d = √(y2-y1)^2 + (x2 - x1)^2
d = √(2-(-7))^2 + (3 - (-10))^2
d = 5√10 = diameter
r = d/2 = 5√10 /2
His total sales were 402.68 dollars. 700 minus 275 minus 22.31
A because x is the original price, so you multiply by the tax (9%) which would convert to 1.09 which you would multiply to the x
