Answer:
5x+10
Step-by-step explanation:
(7x+4) - (2x-6)
Distribute:
7x + 4 - 2x + 6
Combine like terms
5x + 10 (ans)
10 pairs of short cost 10s (without sale).
10% =0.1, and 10% off is
10s - 0.10*10s (B) = 10s -1s (D)
10s -1s = 9s (A)
Expression that does not match is (C),
correct answer is (C).
(I) 2/3 is a zero of P(x)
(II) 0 is a zero of P(x)
(III) (-d/c) is a zero of P(x)
<u>Step-by-step explanation:</u>
<h3>(I) P(x) = 3x - 2</h3>
Here, P(x) = 3x - 2
To find the zeroes of P(x)
let P(x) = 0
∴ 3x - 2 = 0
∴ 3x = 2
∴ x = 2/3
Thus, 2/3 is a zero of P(x)
<h3>(II) P(x) = 9x</h3>
Here, P(x) = 9x
To find the zeroes of P(x)
let P(x) = 0
∴ 9x = 0
∴ x = 0/9
∴ x = 0
Thus, 0 is a zero of P(x)
<h3>(III) P(x) = cx + d, c ≠ 0</h3>
Here, P(x) = cx + d
To find the zeroes of P(x)
let P(x) = 0
∴ cx + d = 0
∴ cx = -d
∴ x = (-d/c)
Thus, (-d/c) is a zero of P(x)
