One solution.. what you're describing is two lines that intersect at the common y intercept. This will be the only point that satisfies both equations in the system.
Answer:
The correct option is last one 77 degrees.
Therefore the measure angle W is 77 degrees.
Step-by-step explanation:
Given:
Exterior angle = 122°
∠W = (2x-13)°
∠Y= x°
To Find:
∠W = (2x-13)° = ?
Solution:
Exterior Angle Property:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Angle W and Angle Y are the interior angles of Exterior angle 122°.
∴ 
Substituting the values we get

Now Substitute 'x' in angle W we get

Therefore the measure angle W is 77 degrees.
Answer:
y+7=25(x+4)
Step-by-step explanation:
It is + because remember two - - negatives make a positive +. And the original formula is like this y-y=m(x-x), then m represents the slope, so your slope will always go in place of the m. And you can number the it y one - y two = m (x one - x two) if that helps. Hope it did help!!!
Answer:
50
Step-by-step explanation:
4 books = 200
1 book = x
Now do cross multiplicaton and divide:
1 x 200 ÷ 4
200 ÷ 4
50
