In figure 1 there are 7 squares, in figure 2 there are 10 squares, figure 3 there are 13 squares. in each figure you are just adding 3. (try to find the patterns.) The equation representing the figures is x+3=y.
<span>calculate circumference first:
C = 2πr
C = 2(3.14159)(8 inches)
C = 50.265 inches
then 60/360 = 1/6 of the circle
50.265 inches / 6 </span><span>
= 8.378 inches (Round answer as needed) </span>
The slope of this line is -1 you find this by using the slip formula of y-y over x-x find two points on the line so I used points (-2,2) and (-1,1) plug them into the formula to get the slope of -1 hope this helps:)
Is there a question for this problom, are we supoosed to find out if billy was thinking right or was he wrong.
Y = 10x + 400
y = 30x + 300
10x + 400 = 30x + 300
20x = 100
x = 5 months(answer to first question)
y = 10(5) + 400
y = 450
After 5 months, Tina will save $450 with either option.
