You need to use trigonometry, and square all of the numbers, you then add the lowest two and they should sum to the other number.
The set that this works for is the correct set.
Hope this helps x
The given quadrilateral ABCD is a parallelogram since the opposite sides are of same length AB and DC is 4 and AD and BC is 2.
<u>Step-by-step explanation</u>:
ABCD is a quadrilateral with their opposite sides are congruent (equal).
The both pairs of opposite sides are given as AB = 3 + x
, DC = 4x
, AD = y + 1
, BC = 2y.
- AB and DC are opposite sides and have same measure of length.
- AD and BC are opposite sides and have same measure of length.
<u>To find the length of AB and DC :</u>
AB = DC
3 + x = 4x
Keep x terms on one side and constant on other side.
3 = 4x - x
3 = 3x
x = 1
Substiute x=1 in AB and DC,
AB = 3+1 = 4
DC = 4(1) = 4
<u>To find the length of AD and BC :</u>
AD = BC
y + 1 = 2y
Keep y terms on one side and constant on other side.
2y-y = 1
y = 1
Substiute y=1 in AD and BC,
AD = 1+1 = 2
BC = 2(1) = 2
Therefore, the opposite sides are of same length AB and DC is 4 and AD and BC is 2. The given quadrilateral ABCD is a parallelogram.
Answer:
(3/2,3)
Step-by-step explanation:
1.Rewrite the equation
y=3 2x=3
2.Solve the equation
y=3 x=3/2
(x,y)=(3/2,3)
What is the outliner of 279,593,593,597,599,606,611,613,615,619,

Step-by-step explanation:
Answer:
C) y = 2 lxl - 4
Step-by-step explanation:
The general form of an absolute value function:
f(x) = a l x - h l + k, where "a" represents vertical stretches, and whether the open up or down.
If a is positive, it open up word.
h and k how far the graph shifts horizontally and vertically.
Here the given graph open up word. Therefore, a is positive.
h = 0 and k = -4 shifts down.
Therefore, the given graph y = 2lxl -4
The answer is C) y = 2 lxl - 4
Hope you will understand the concept.
Thank you.
