Answer:
Step-by-step explanation:
y = -5x - 17
in y = mx + b form, the y int is in the m position
y = mx + b
y = -5x - 17......so the y int (b) = -17 or (0,-17) <=== y intercept
u can also find the y intercept by subbing in 0 for x and solving for y
u can find the x intercept by subbing in 0 for y and solving for x
y = -5x - 17
0 = -5x - 17
5x = -17
x = -17/5......so the x intercept is -17/5 or (0,-17/5) <==== x intercept
The answer to that would be 3/8
Answer:
36 dollars
Step-by-step explanation:
We need to think backwards to solve this question.
(8 - 2) x 2 = 12
(12 - 2) x 2 = 20
(20 - 2) x 2 = 36
Area of sector=fraction of sector times area of circle
fraction of sector=degrees/360
and area of circle=pir^2
so
hold a sec, we have the wiper on the outside, so we want to find the outside ring thing
do
area big sector-area small sector
or even better
(degrees/360) times (area big-areasmall)
big is 10
small is 4 (10-6=4)
areabig=10^2 times pi or 100pi
areasmall=4^2 times pi or 16pi
areabig-areasmall=100pi-16pi=84pi
then find the fraction
84pi times (150/360)=35pi square inches
