Solve |x + 3|= -6
Rudik [331]

Answer:

The equation has NO solution ⇒ C

Step-by-step explanation:

  • An absolute value of a number means the value of the number without its sign
  • IxI = m, then x = m or x = -m
  • Example: I2I = 2 and I-2I = 2

<u><em>V.I.N:</em></u><em> </em>

  • <em>Absolute </em><em>never give a negative</em><em> value</em>
  • <em>If the number </em><em>on the other side of the equation negative</em><em> then the </em><em>equation has no solution</em>

Let us solve the question

∵ Ix + 3I = -6

∵ The right side of the equation is negative

∵ Absolute never give a negative value

→ By using the 2nd note above

∴ The equation has NO solution

What is the value of (6a-2)
DanielleElmas [232]
It totally depends on the value of 'a', and if 'a' changes, then (6a-2) immediately changes too. Whatever 'a' is at the moment, (6a-2) is 2 less than 6 times 'a'.

Find the seventh term of the
jekas [21]

Answer:

T_7 = \frac{64}{729}

Step-by-step explanation:

Given

a =1

r = \frac{2}{3}

Required

Determine the 7th term

The nth term of a gp is:

T_n = a * r^{n-1

So, we have:

T_7 = 1 * \frac{2}{3}^{7-1

T_7 = 1 * \frac{2}{3}^{6

T_7 = 1 * \frac{2^6}{3^6}

T_7 = 1 * \frac{64}{729}

T_7 = \frac{64}{729}
