Addis Ababa is the capital of Ethiopa.
Dress pants for $ 40, a shirt for $ 30, a tie for $ 20
he uses the dress pants coupon....which is the second coupon which gives him y percent off the dress pants
so ur answer is : (1 - y) * 40
Step-by-step explanation:
7(x + 6) = 42
<em>distributive property</em><em>: a(b + c) = ab + ac</em>
(7)(x) + (7)(6) = 42
7x + 42 = 42
<em>subtraction property of equality</em><em> (subtract 42 from both sides)</em>
7x + 42 - 42 = 42 - 42
7x = 0
<em>division property of equality </em><em> (divide both sides by 7)</em>
7x : 7 = 0 : 7
x = 0
Answer:
This is called a mid segment theorem in which the al ine segment (DE) joining the midpoints of two sides of a triangle is parallel to the third side.
Step-by-step explanation:
Suppose we have a triangle ABC. Then the midpoints can be located as D, E and F. If we join D , E and F another triangle is formed.
From the figure we can see that
AE≅ CE
AD≅DB
BF≅CF
BECAUSE all the given points are the midpoints which divide the lines into two equal halves.
If we increase the line DE to a point L we find out that DL is parallel to BC i.e. it does not meet at any point with BC. ( the two lines do not meet)
(1)
If we join C with L we find out that the the line DE is half in length to the line BC.
AS
AE= CE (midpoints dividing into equal line segements.)
LE= DE
Triangle CEL= Triangle DEF
so
DL= BC
But DE = 1/2 DL
therefore
DE= 1/2 BC (2)
Therefore from 1 and 2 we find that a line segment (DE) joining the midpoints of two sides of a triangle is parallel to the third side
Answer:
(x − 7)² + (y + 2)² = 52
Step-by-step explanation:
The equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
We know that (h, k) = (7, -2). But we need to find the radius. To do that, find the distance from the center to a point on the edge:
r² = (x₁ − x₂)² + (y₁ − y₂)²
r² = (7 − 1)² + (-2 − -6)²
r² = 6² + 4²
r² = 36 + 16
r² = 52
So the equation of the circle is:
(x − 7)² + (y + 2)² = 52
