Answer:
4x + 8y = 50 or 4x + 8y > 50
Step-by-step explanation:
To find which equation show the exact answer, Becasue he need at least 50 poitns to have a B, so:
4x + 8y must larger or equal to 50
In these choice, some I can't figure out what it means but the correct answer for this is:
4x + 8y = 50 or 4x + 8y > 50
Hope this help you :3
<h2>Steps:</h2>
So for this, we will be completing the square to solve for m. Firstly, subtract 8 on both sides:
Next, divide both sides by 2:
Next, we want to make the left side of the equation a perfect square. To find the constant of this perfect square, divide the m coefficient by 2, then square the quotient. In this case:
-8 ÷ 2 = -4, (-4)² = 16
Add 16 to both sides of the equation:
Next, factor the left side:
Next, square root both sides of the equation:
Next, add 4 to both sides of the equation:
Now, while this is your answer, you can further simplify the radical using the product rule of radicals:
- Product rule of radicals: √ab = √a × √b
√12 = √4 × √3 = 2√3.
