The table shows the balance of two accounts each year for four years. Determine whether each balance is linear or nonlinear. Then predict which account will have a greater balance in Year 3.
Year, t Account A Balance Account B Balance
0 $450 $550
1 $504 $570
2 $564.48 $590
Account A Balance is linear. Account B Balance is nonlinear. Account A will have a greater balance in Year 3.
Account A Balance is nonlinear. Account B Balance is linear. Account A will have a greater balance in Year 3.
Account A Balance is linear. Account B Balance is nonlinear. Account B will have a greater balance in Year 3.
Account A Balance is nonlinear. Account B Balance is linear. Account B will have a greater balance in Year 3.

Account A Balance is nonlinear. Account B Balance is linear. Account A will have a greater balance in Year 3. Then the correct option is B.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
The slope for account A is calculated as,
m = (504 - 450) / (1 - 0) = (564 - 504) / (2 - 1)
54 ≠ 60
Account A is non-linear. The amount after 3 years will be more than $620 ($564 + $60).
The slope for account B is calculated as,
m = (570 - 550) / (1 - 0) = (590 - 570) / (2 - 1)
20 = 20
Account A is linear. The amount after 3 years will be $610 ($590 + $20).

PLEASE HELP I"LL MARK YOU THE BRAINLEST AND GIVE YOU ADDITIONAL POINTS> HELP ITS DUE VERY SOON. To answer this question you must divide the shape into two triangles and a rectangle and add the sums of the areas together.
You work as a custodian at a school and are responsible for wiping cafeteria tables in the shape shown. Each spray bottle covers 200 square feet, and you need to clean 6 tables.
If you have 4 bottles of spray, do you have enough to clean all 6 tables?
Yes, because the area of all 6 tables is 420 sq. ft., and the spray covers 800 sq. ft.
Yes, because the area of all 6 tables is 432 sq. ft., and the spray covers 800 sq. ft.
Yes, because the area of all 6 tables is 768 sq. ft., and the spray covers 800 sq. ft.
No, because the area of all 6 tables is 804 sq. ft., and the spray only covers 800 sq. ft.

hope this will be helpful to you .
8•3= 24
24• 1/2= 12
This means 12 is the area of one triangle, but we have two of those so...
12+12=24
Now to find the area of the rectangle we do (b•h)
16•8= 128
Add it all together and...
128+ 24= 152
We have 6 tables in total so multiply it by 6
152• 6= 912
We have 6 tables so...
156•6= 912 sq
There we go. We need 912 sq, and we only have enough to cover 800 sq. So no.

Answers
Answer:
let dimention of original garden be x
then (x-8)(x-5) = 180
x^2 -13x -140 = 0
(x-20)(x+7)=0
x= 20 or x = -7
x = 20
original area = (20)^2
= 400 m^2

Find the measure of < 3 in the figure if the measure of < 2 is 130
Answers
Answer:
50
Step-by-step explanation:
All angles around a circle is 360°
/_ 2 = 130°
/_ 1 = 130° (Vertically opposite angles)
= 130° + 130° = 260°
all angles = 360°
= 360° - 260° = 100°
= 100° ÷ 2
= 50°
= /_ 3 and /_ 4 = 50°
Verification = 130° + 130° + 50° + 50° = 360°
