Answer:

[-9 ≤ x] or [x ≥ -9]

Step-by-step explanation:

<u>QUESTION :-</u>

Find the solution set of →  \frac{1}{3} x - 4 \leq  2+ x

<u>SOLUTION :-</u>

  • Simplify the L.H.S.

=> \frac{x-12}{3} \leq x + 2

  • Multiply both the sides by 3

=> \frac{x - 12}{3} \times 3 \leq 3(x + 2)

=> x - 12 \leq  3x +6

  • Substract 'x' from both the sides

=> x - 12 - x \leq 3x + 6 -x

=> -12 \leq 2x + 6

  • Substract 6 from both the sides.

=> -12 - 6 \leq 2x + 6 - 6

=> -18 \leq  2x

  • Divide both the sides by 2.

=> \frac{-18}{2} \leq \frac{2x}{2}

=> -9 \leq x  or  x \geq -9

Which of the following is most likely to be a relative minimum for this graph?
olga55 [171]

Answer: A (3, -4)

Step-by-step explanation:

A minimum is at the lowest point on the parabola. The minimum and maximum can be seen by looking at the vertex.

If you go right 3 spaces on the x-axis horizontally, then down 4 spaces vertically on the y-axis you get (3, -4).

4 is negative because you are going down below the x-axis.

Replace the ___ with &lt;, &gt;, or = to make a true statement. 7^4/7^2(fraction) ___ 49
Brrunno [24]
Use this exponent property;
\dfrac{a^m}{a^n} = a^{m-n}

So you have \dfrac{7^4}{7^2} =7^{4-2} = 7^2 = \boxed{49}

So you should use "=".
