Answer:
(0,-7)
Step-by-step explanation:
the y-intercept is found when the x-value is equal to 0. In this case, we are finding a coordinate pair. First, plug in 0 for x.
7+y=4.3(0)
simplify
7+y=0
subtract 7 from both sides
y=-7
Make it an ordered pair,
(0,-7)
the sum of all interior angles in a polygon is 180(n - 2), where n = number of sides.
well, this is a quadrilateral, so it has 4 sides so it has a total of interior angles of 180(4-2) = 360°, since this is a kite, then <u>one pair of opposite angles are congruent</u>, namely ∡C = ∡A.
360° - 45° - 100° = 215°, and ∡C and ∡A split that evenly, so ∡C = 107.5°.
The answer is B AC
because it's the 2 that connect the line between A and C
Answer:
Ln or an = 3n - 16
Step-by-step explanation:
This is an arithmetic series. You are adding 4 to get the next term.
Ln = a + (n - 1)d
Ln is the last term or the nth term.
a = - 13
d = 3
Solution
Ln = - 13 + (n - 1)3 Remove the brackets
Ln = - 13 + 3n - 3 Combine like terms
Ln = -16 + 3n or
Ln = 3n - 16
