I'm assuming that you are given the equation f(x) = 2x^2 + 3 and the value f(-3).
To find this, all you need to do is plug in the value of -3 in f(x) for all x values. It would look like:
All you need to do is simplify:
Your final answer is f(x) = 21.
= √(24 - 6)
= √18
= 4.24

Step-by-step explanation:
<u>Step 1: Define Equation</u>
6n + 7 = 55
<u>Step 2: Solve for </u><em><u>n</u></em>
- Subtract 7 on both sides: 6n = 48
- Divide 6 on both sides: n = 8
<u>Step 3: Check</u>
<em>Plug in n into the original equation to verify it's a solution.</em>
- Substitute in <em>n</em>: 6(8) + 7 = 55
- Multiply: 48 + 7 = 55
- Add: 55 = 55
Here we see that 55 does indeed equal 55.
∴ n = 8 is a solution of the equation.
18/24 = pink roses... 75% of the roses are pink.
