The answer is <span>B. |w – 48| ≤ 8.
w - the weight of the box
</span>The weight of the box must be within 8 pounds: w ≤ 8
The weight of the box must be within 8 pounds of a standard lifting weight of <u>48 pounds</u>: <span>|w – 48| ≤ 8</span>
Distribute -3.2 through the parentheses
Cancel equal terms on both sides of the equation
Add the decimals
<em>Thus, The expression are equivalent at b = 9.12...~</em>
Step-by-step explanation:
Select all of the following that are quadratic equations.
x² + 3x - 5 = 0 ✓
x² - x = 3x + 7 ✓
5x - 7 = 0 X
7x² + 14x = 0 ✓
x³ - 3x² + 1 = 0 X
x - 5 = 9x + 7 X
What is quadratic equations?
Quadratic equations is a equation that has a general form like "ax² + bx = c"
For example :
x² + 3x - 5 = 0
x² + 3x = 5
x² → ax²
3x → bx
5 → c
