232. Сколько решений имеет уравнение | х + 3 | -один?
marysya [2.9K]

Answer: <em>уравнение имеет 2 решения:</em>

<em>               x₁ = - 4;    x₂ = - 2.</em>

Step-by-step explanation:

<em>Ix + 3I = 1</em>

<em>1) x + 3 = 1</em>

<em>   x + 3 - 3 = 1 - 3</em>

<em>   x = -2</em>

<em>2) - (x + 3) = 1</em>

<em>    x + 3 = - 1</em>

<em>    x + 3 - 3 = - 1 - 3</em>

<em>    x = - 4</em>

Calculate the velocity of a moving train with a mass 10,000kg and 150,000J of energy.
Viefleur [7K]
Kinetic energy possessed by moving train is E_k = 150000J.

And mass m = 10000kg.

The formula for kinetic energy is E_k = \frac{m\times v^2}{2}.

Solve for velocity:

E_k = \frac{m\times v^2}{2}\implies 2E_k = m\times v^2

v^2=\frac{2E_k}{m}\implies \underline{v = \sqrt{\frac{2E_k}{m}}}

Now put in the data:

v = \sqrt{\frac{2\times150000J}{10000kg}}\approx5.48\frac{m}{s}

Which inequality represents the values of x that ensure triangle ABC exists? a triangle with side lengths of 6.5 units, 3.5 unit
nikdorinn [45]

Answer:

1 < x < 7.5

Step-by-step explanation:

This problem can be solved using given below property of triangle.

Sum of two sides is always greater than third side of triangle.

Difference of two sides is always lesser than third side of triangle.

_______________________________________________

Given

sides length

6.5 units

3.5 units

Third side is 2.5 +  x

using the property, Sum of two sides is always greater than third side of triangle.

6.5 + 3.5 > 2.5 +x

=>10 >2.5 + x

=>2.5 + x< 10

=> x< 10 -2.5

=> x < 7.5

using the property, Difference of two sides is always lesser than third side of triangle.

6.5 - 3.5 >  2.5 +x

=>3.5 >  2.5 +x

=> 2.5 +x  > 3.5

=> x  > 3.5 - 2.5

=> x  > 1

combining both we have

1 < x < 7.5

out of the given option none is 1 < x < 7.5

hence, correct answer will be 1 < x < 7.5 and wrong option can be claimed by student.
