Answer:

Mistakes:

Used addition

Didn't flip inequality form

Corrections:

Divide each term

Instead of a positive value it should be negative

flip the direction of the inequality form

Step-by-step explanation:

- 9x \div  - 9  \leqslant 90 \div – 9

cancel the common factor

\times  \leqslant 90 \div  - 9

Divide 90 by – 9

Answer is:

\times  \leqslant  - 10

Hope this helps!

Let f(x) = 3x + 2 and g(x) =7x + 6. Find f ·g and its domain.
Kitty [74]

Answer:

The answer is the option D

21x^{2}+32x+12 ; All real numbers

Step-by-step explanation:

we have

f(x) = 3x + 2

g(x) =7x + 6

Calculate f(x)*g(x)

(3x + 2)*(7x+6)

Multiply applying the distributive property

(3x + 2)*(7x+6)=3x*7x+3x*6+2*7x+2*6\\=21x^{2}+18x+14x+12\\=21x^{2}+32x+12

The domain of the function is the interval------> (-∞,∞)

All real numbers

Butoxors [25]

Answer:

the people would save 12 meters

Step-by-step explanation:

If it is a right triangle that has 45,45,90 angles, Than two side lengths would be the same, so there are two 30 meter side lengths. The path is 48 meters long, and the road would be 60 meters long (30+30), so you subtract 48 from 60, and get 12. You would save 12 meters

Colton earns $35 per lawn he mows. In kne day he mows four lawns and he works five days a week for 20 weeks a year. His expenses
yanalaym [24]

Answer:

1) Consider that he makes $1189 every two weeks engaged with work

2) An estimate of the opportunity cost of going on the fishing trip is $1450 in two weeks

3). If he decides to buy the truck, he has to work for about 7 weeks before going on the fishing trip

Step-by-step explanation:

From the given data

Total revenue from lawn mowing per year = 35 × 4× 5×20 = $1400

Similarly total operating costs = $2110

Total profit per annum = $11890

However total revenue per every 2 weeks = $1189

To buy the truck, sell his and go on the fishing trip it will cost = 5200-1500+250 =$3950 hence he has to work for about 6.64 or approximately 7 weeks before going on the fishing trip

2) Opportunity cost will factor in the cost of having someone work for him while away

The cost is = $250 + $120/day

Hence in two weeks it will cost him $1450

3) He has to work for about 7 weeks to be able to afford the truck
