Answer : Second Option is correct.
Explanation :
Since we have given in the figure ,
AE=12 units
AD=9 units
EB=4 units
DC=x units
By using the BPT theorem, which states that
"If a line is drawn parallel to one side of a triangle in distinct point , the other sides are divided in the same ratio."
So, here we have a ΔABC,
in which DE║BC as shown in the figure ,
so, by using the BPT we get,
Hence, length of DC = 3 units .
Answer:
B = (-11, -17)
C = (11, -17)
Step-by-step explanation:
Reflection over the x-axis is accomplished by changing the sign of the y-coordinate:
(x, y) ⇒ (x, -y) . . . . . reflection over x-axis
Reflection over the y-axis is accomplished by changing the sign of the x-coordinate:
(x, y) ⇒ (-x, y) . . . . . reflection over the y-axis
__
B = (-11, -17)
C = (11, -17)
__
<em>Check</em>
Reflection over both axes negates both coordinates. It is equivalent to reflection over the origin, or rotation 180°.
A(-11, 17) ⇒ C(11, -17) . . . . . both coordinates change sign
Answer:
100th term = -1485
Step-by-step explanation:
<h3>Arithmetic Progressionthe </h3><h3>nth term, Tn:</h3>
n = number of terms
= 100
a = first term
= 5
d = difference
= second term - first term
= 2 - 5
= -3
substitute the values into the formula
Answer:
The original price of computer is $ 1040
Solution:
Given that, Mason used a 30% coupon to buy a new computer
After the discount, the cost of the computer was $728
To find: original price of computer
From given question,
price after discount = $ 728
discount = 30 % of original price
Let "x" be the original price of computer
price after discount = original price - discount price
Step-by-step explanation:
