Solve for x under the assumption that x<0. x-5/x<4

Mathematics

AleksandrR [38]3 years ago
3 0
If you would like to solve the inequality x - 5/x < 4, you can do this using the following steps:

<span>x - 5/x < 4
</span>x^2 - 5 < 4x
x^2 - 4x - 5 < 0
(x - 5) * (x + 1) < 0
x < 0
1. x = 5
2. x = -1

The correct result would be x = -1.

Which choice correctly expresses the solution set in the inequality in words?
Vera_Pavlovna [14]

Answer:

The answer to your question is letter A.

Step-by-step explanation:

Inequality                   x + 2 ≥  5

Solve the inequality, remember that inequalities and equations are solved in similar ways.

- Subtract 2 in both sides

                                   x +2 - 2 ≥ 5 - 2

- Simplify

                                          x ≥ 3      

- Remember that this sign "≥" means that x is greater or equal to a number, and this sign "≤" means that x is lower or equal to a number.

The option that satisfies our inequality is the first option.

The population of a certain geographic region is approximately 103 million and grows continuously at a relative growth rate of 1
vladimir2022 [97]
Ok because it only wants 3 significant digits your just take 103 and times it by the decimal form of 1.67% which is .0167 to get 1.720, now add that to 103 and multiply by .0167 again to get the populations after the second year(Use the population at that year to multiply by .0167). Do the same for the 3rd, 4th and 5th years and you should end with 112 million people.

The number of fish in a lake decreased by 25% between last year and this year. Last year there were 60 fish in the lake. What is
11111nata11111 [884]

Answer:

45

Step-by-step explanation:

Decreasing by 25% means that there is 25% less of last years amount or 0.25x less. It also means that this year there is only 75% of what was last year actually in the lake or 0.75x. Since last year, there were 60 fish, this means this year there is 0.75(60) = 45. This year has 45 fish.
