Which ordered pair is a solution to the equation y = -6x?
(12, -2)
(3,-9)
-10.60)
(18, -3)

Answers

Answer:

(-10; 60)

Step-by-step explanation:

y = -6x

(12; -2)

-2 = -6 · 12

-2 = -72 - no

(3; -9)

-9 = -6 · 3

-9 = -18 - no

(-10; 60)

60 = -6 · (-10)

60 = 60 -  yes

(18; -3)

-3 = -6 · 18

-3 = -78 - no

Solve for b at the top
And x at the bottom
I’ll give 17 points

Answers

Answer:

b = -1

x = 1

Step-by-step explanation:

8 - (b - 2) = 11

subtract 8 from both sides

- (b - 2) = 3

distribute

-b + 2 = 3

subtract 2 from both sides

-b = 1

now, to make the b positive, we make the other side negative by multiplying.

b = -1

-2x+ 4 = 5 -3x

subtract 4 from both sides

-2x = 1 -3x

add 3x to both sides

1x = 1

divide by 1

x = 1

The number of people that attended the first basketball game of the season was 840. The number of people attending the last basketball game of the season increased by 30%. How many people attended the last basketball game

Answers

Answer:

1092 people attended the last basketball game.

Step-by-step explanation:

Given that:

Number of people who attended the first basketball game = 840

Percent increase for last game = 30%

Total people who attended last game = (100+30)% = 130% of first game

Number of people who attended last game = [tex]\frac{130}{100}*840[/tex]

Number of people who attended last game = 1.30*840 = 1092

Hence,

1092 people attended the last basketball game.

i need to find x & y. plz answer i really need thisssss. only if correct :)

Answers

Answer:

x=12, y= 20

Step-by-step explanation:

We can find x using the pythagorean thereom because ABD is a right triangle.(D is the point between segments with legnth 5 and 11)

AC^2 + CD^2 = AD^2

x^2 + 5^2 = 13^2

x^2 = 25 = 169

x^2 = 144

x = 12

We may now find y using the pythagorean thereom because ABC is a right triangle. Right now we know x = 12

AC^2 + CB ^2 = AB^2

12^2 + 16^2 = y^2

144 + 256 = y^2

y^2 = 400

y= 20

Kara Williams is the new controller for Colors, a designer and manufacturer of sportswear. Shortly before the December 31 fiscal year-end, Lashea Lucas (the company president) asks Williams how things look for the year-end numbers. Lucas is not happy to learn that earnings growth may be below 10% for the first time in the company's five-year history. Lucas explains that financial analysts have again predicted a 12% earnings growth for the company and that she does not intend to disappoint them. She suggests that Williams talk to the assistant controller, who can explain how the previous controller dealt with this situation. The assistant controller suggests the following strategies:a. Postpone planned advertising expenditures from December to January.b. Do not record sales returns and allowances on the basis that they are individually immaterial.c. Persuade retail customers to accelerate January orders to December.d. Reduce the allowance for bad debts (and bad debts expense).e. Colors ships finished goods to public warehouses across the country for temporary storage until it receives firm orders from customers. As Colors receives orders, it directs the warehouse to ship the goods to nearby customers. The assistant controller suggests recording goods sent to the public warehouses as sales.RequirementWhich of these suggested strategies are inconsistent with IMA standards?
