Given the <span>piecewise function f(x) is defined below
</span> f(x)= \left \{ {{x^2+1; \ \ \ -4 \leq x \ \textless \ 1} \atop {-x^2; \ \ \ 1 \leq x\ \textless \ 2}} \atop {3x; \ \ \ x \geq 2} \right.

In the piecewise function, we use the top function, when x has a value from -4 to 1, 1 not included. We use the middle function when x has a value from 1 to 2, 2 not included. And we use the bottom function when x has a value of 2 and above.

Therefore, to find f(1), we make use of the middle function.
f(1) = -(1)^2=-1

just divide Atlantic/Mississippi

\frac{3.1 \times  {10}^{17} }{6.3 \times  {10}^{11} }  =  \frac{3.1}{6.3}  \times  \frac{ {10}^{17} }{ {10}^{11} }  \\  = 0.492 \times  {10}^{17 - 11}  \\  = 0.492 \times  {10}^{6}  \\  = 4.92 \times  {10}^{5}

0.75h + 3 = 12 <br> What's the answer?
kykrilka [37]

Answer:

h = 12

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

0.75h + 3 = 12

<u>Step 2: Solve for </u><em><u>h</u></em>

  1. Subtract 3 on both sides:                    0.75h = 9
  2. Divide 0.75 on both sides:                  h = 12

<u>Step 3: Check</u>

<em>Plug in h into the original equation to verify it's a solution.</em>

  1. Substitute in <em>h</em>:                    0.75(12) + 3 = 12
  2. Multiply:                               9 + 3 = 12
  3. Add:                                     12 = 12

Here we see that 12 does indeed equal 12.

∴ h = 12 is a solution of the equation.
