Answer: Polygons - Quadrilaterals
sum of the interior angles of a quadrilateral is 360 degrees.
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
The vertex is like the top point of the pyramid. If we cut in that direction, we essentially cut the pyramid in half. This makes a triangle crossection
Line BC passes through (-5,5) and (0 ,1)
Slope = 5-1/-5-0 = -4/5
Line BC cuts the y-axis at (0,1)
⇒ y-intercept must be 1
General Equation of a linear line: y = mx + b
Plug m = -4/5 and b = 1 into the general equation and find the equation of line BC:
y = -4/5x + 1
Multiply by 5 on both sides:
5y = -4x + 5
Add 4x to both sides:
4x + 5y = 5
Answer: 4x + 5y = 5 (Option C)
First, I would find the difference of 82 and 26: 82 - 26 = 56.
Since there are 7 days in a week, I'd divide 56 by 7: 56/7 = 8.
Therefore, the average weekly change is $8.
