Solve: I 2x +5 I + 6 ≥ 4

Mathematics
1 answer:
masya89 [10]3 years ago
4 0

Answer:

Step-by-step explanation:

This is an absolute value problem.

If we begin a tentative solution by subtracting 6 from both sides, we get

I 2x +5 I + 6 ≥ 4  =>   I 2x +5 I  ≥ -2

Note well that  I 2x +5 I has a value of 0 or greater; it cannot be negative.

Thus  I 2x +5 I  ≥ -2 has no solution.

Which of the following is the solution for the inequality below? -3x+2<8
Zepler [3.9K]

Answer:

x>-2

Step-by-step explanation:

First you have to subtract 2 from both sides, which leaves you with -3x=6, then you have to divide -3 on both sides to get the variable by itself. Which is x<-2, but you have to switch the sign because you multiplied/divided by a negative number, then you get left with x>-2........Hope that helped!!!!!!!!!!:)

Find the value of each variables
BigorU [14]

Answer:

<em>X=11</em>

<em>y=22</em>

Step-by-step explanation:

tan60\frac{11\sqrt{3} }{x} \\\\\sqrt{3} =\frac{11\sqrt{3} }{x} \\\\x=\frac{11\sqrt{3} }{\sqrt{3} }

⇒x=11

Sib 60=\frac{11\sqrt{3} }{y} \\\\\frac{\sqrt{3} }{2} =\frac{11\sqrt{3} }{y} \\\\y=\frac{11\sqrt{3} }{\sqrt{\frac{3}{2} } }

⇒ y=22

<u>hope it helps....</u>
