Answer: x\leq 3

PLEASE MARK ME BRAINLIEST

Step-by-step explanation:

1) Simplify both sides of the inequality:

4x+8\geq 5x+5

2) Subtract 5x from both sides:

4x+8-5x\geq 5x+5-5x

3) Simplify:

-x+8\geq 5

4) Subtract 8 from both sides:

-x+8-8\geq 5-8

5) Simplify:

-x\geq -3

6) Divide both sides by -1:

\frac{-x}{-1} =\frac{-3}{-1}

7) Simplify:

x\leq -3

Determinați domeniul de definiție al funcției f:D→R, f(x)=(√2-3x)+2
Rudik [331]

Answer:

The domain is all real numbers less than or equal to two-third

Step-by-step explanation:

<u><em>The question in English is</em></u>

Determine the domain of the function f :D→R, f(x)=\sqrt{2-3x}+2

we know that

The radicand of the function must be greater than or equal to zero

so

2-3x \geq 0

Solve the inequality for x

subtract 2 both sides

-3x \geq -2

Multiply by -1 both sides

3x \leq 2

Divide by 3 both sides

x \leq \frac{2}{3}

The solution is the interval ----> (-∞,2/3]

therefore

The domain is all real numbers less than or equal to two-third

Can you please solve and explain how. I dont have any idea :(
mezya [45]

From the expression 2f + 5(8-f), we know that Karla caught f purple dot fish, and (8-f) green dot fish, because green dot fish gives 5 points.

2f -points for the purple dot fish, f is a number of the purple dot fish.

5(8-f) - points for the green dot fish, (8-f) is a number of the green dot fish.

So,

altogether she made 8 attempts.

One attempt cost 50 cents,

8 attempts cost 8*50=400 cents = $ 4.

Answer is B. 4 (dollars).
