in the expression -9x - 2x^2 + 7, what is the coefficient of x?
The coefficient of x is -9.
what about the other ones?
2x^2 + 8 - 4x + 6x^2 + 7 simplifies to 8x^2 - 4x + 15
4x^2 + 8x - 11x + 6 - 5x^2 + 2 simplifies to -x^2 - 3x + 8
(m^2 - m) + (3 + m - 1)
(7x^2 - x -2) - (-6x^3 + 3)
(m^2 - m) + (3 + m - 1) simplifies to m^2 + 2
(7x^2 - x - 2) - (-6x^3 + 3) simplifies to 6x^3 + 7x^ 2 - x - 5
Suppose you earned 7t - 1 dollars on Monday and 8t + 5 dollars on Tuesday. What were your total earnings? Simplify your answer.
f^2 * f^4
100^12/100^8
x^13/x^2
4^4 * 4/^10
2^22 * 2^22
4^5/4^5
2^2/2^5
Total earnings = (7t - 1) + (8t + 5) = 15t + 4
f^2 * f^4 = f^(2+4) = f^6
100^12/100^8 = 100^(12-8) = 100^4
x^13/x^2 = x^(13-2) = x^11
4^4 * 4^10 = 4^(4+10) = 4^14
2^22 * 2^22 = 2^(22+22) = 2^44
4^5/4^5 = 1
2^2/2^5 = 1/2^3 = 1/8
