Answer:
8000
Step-by-step explanation:
Total number of homes in given data is 7+33+56+42+12 = 150
Now out of 150 there is 12 homes who have 4 or more phones
Let's set up proportions
150 / 12 = 100,000 / X
x=100000×12 /150
X=8000
We can use the points (13, 11) and (14, 6) to solve.
Slope formula: y2-y1/x2-x1
= 6-11/14-13
= -5/1
= -5
Therefore, the slope is -5.
Best of Luck!
Answer:
Step-by-step explanation:
y + 2 = -7(x + 7)
y + 2 = -7x - 49
y = -7x - 51
answer is b
Subtract $3 from $21 to get the cost of skating for three hours without the rental fee. 21-3=18. $18 was spent on skating for three hours so you'll divide 18 by 3 to get the hourly rate. 18/3=6.
C(x)=6x+3
If the whole perimeter of the pasture is 500 yards, and one side is 150 yards (the opposite side is 150 as well), the other side has to be 100 yards (the equivalent being 100).
Proof Check: 150+150=300 yds.
100+100=200 yds.
300+200=500yds.
