Which value was affected the most: range
Distribute sum groups
x(x^2 + 4x - 2) - 5(x^2 + 4x - 2)
Distribute
x^3 + 4x^2 - 2x - 5(x^2 + 4x - 2)
Distribute
x^3 + 4x^2 - 2x - (5x^2 + 20x - 10)
Simplify brackets
x^3 + 4x^2 - 2x - 5x^2 - 20x + 10
Collect like terms
x^3 + (4x^2 - 5x^2) + (-2x - 20x) + 10
Simplify
<u>x^3 - x^2 - 22x + 10</u>
Answer:
Step-by-step explanation:
Here's a completely valid trick for finding the equation of this new line:
Start with the given 2x + 4y = 6. Replace that '6' with 'C.' We need to find C. To do this, replace x with 6 and y with 4 and calculate C:
2(6) + 4(4) = C, or 12 + 16 = C. Thus, C = 28, and the desired equation is
2x + 4y = 28, or (in simplified form) x + 2y = 14
