13500 because if it increases the answer would be 18,000 people. if 18,000 decreases by 25 the answer is 13500
it to calculate the cost of $100 for every 50lbs, you would use 100x
then you need to add that to the 1200
so the equation would be y = 1200+100x
B is the correct answer
Answer:
irst, solve for two points which solve the equation and plot these points:
First Point: For
x
=
0
f
(
0
)
=
(
−
2
⋅
0
)
−
3
f
(
0
)
=
0
−
3
f
(
0
)
=
−
3
or
(
0
,
−
3
)
Second Point: For
x
=
−
2
f
(
−
2
)
=
(
−
2
⋅
−
2
)
−
3
f
(

)
=

−

f
(

2
)
=
1
or
(
−
2
,
1
)
We can next plot the two points on the coordinate plane:
graph{(x^2+(y+3)^2-0.035)((x+2)^2+(y-1)^2-0.035)=0 [-10, 10, -5, 5]}
Now, we can draw a straight line through the two points to graph the line:
graph{(y + 2x + 3)(x^2+(y+3)^2-0.035)((x+2)^2+(y-1)^2-0.035)=0 [-10, 10, -5, 5]}
Step-by-step explanation:
Step-by-step explanation:
let the number of cookies sold on first week be=x
let the number of cookies sold on second week be= x+4
let the number of cookies sold on third week be= (x+4)×2
total number of cookies sold = 351
now 351=(x)+(x+4)+(x+4)×2
351=3x+(4+4×2)
351=3x+12
3x=351-12
3x=339
x=339÷3
x=11
Cookies sold on first week=113
Cookies sold on second week= 113+4= 117
Cookies sold on third week =113+4×2 = 113+8=121
now add all the number of cookies solved for confirmation
=113+ 117+ 121= 351
