A proportional relationship is a relationship between two equal ratios.
Answer:
x = 5 or 1
Step-by-step explanation:
Square both sides to get
x^2 - 6x + 9 = 4 now subtract four from both sides
x^2 -6x+5 = 0 now factor ( or use quadratic formula)
(x-5)(x-1) = 0 so x = 5 or 1
Find the sum of the interior angles of a 22-gon. Since the polygon has 22 sides, we can substitute this number for n: (n 2)180˚= (22 2)180˚= 20180˚= 3600˚. Each angle of a regular polygon measures 157.5˚.
Answer:
Distance is 6.7units to the nearest tenth.
Explanation:
To solve this problem, we the distance formula. And this is given as:

We were given the equation:
y = 2 x + 4
This can also be rewritten as:
y – 2 x – 4 = 0.
Therefore, a = -2, b = 1 and c = -4
Also, we were given the points:
(x, y) = (–4, 11)
Making use of the above formula for distance, we have:


D = 6.7units (to the nearest tenth)
