Step-by-step explanation:
=0.5*13*18.2
It reveals whether the answers will be negative, and how many solutions the equation will have.
Answer:
11 kittens and 12 parakeets
Step-by-step explanation:
each kitten has 4 feet while each parakeet has 2
11 x 4 = 44 (kittens)
12 x 2 = 24 (parakeets)
11 + 12 is 23 which is your 23 heads.
44 + 24 is 68 which would be your feet
The y intercept is - 1
It is where the line touches or crosses the y axis

Answer: D) 95</h3>
===============================================================
Explanation:
First, let's calculate angle BYC. This is the angle formed by the chords that subtend the arcs mentioned. This angle faces or is aimed toward the direction of the arcs. To find this angle, we'll average the arc measures like so:
angle BYC = (arcAD + arcBC)/2
angle BYC = (50+120)/2
angle BYC = 170/2
angle BYC = 85 degrees
Then we'll use the idea that angles BYC and DYC are supplementary (aka they form a straight 180 degree angle)
angleBYC + angleDYC = 180
angleDYC = 180 - angleBYC
angleDYC = 180 - 85
angleDYC = 95 degrees
which is why the answer is choice D.
