Answer: huh ?
Step-by-step explanation:
Answer:
4x -51
Step-by-step explanation:
m(n(x)) = m(x - 10) = 4(x-10) - 11 = 4x -40 -11 = 4x -51
$720 * .06 = 43.2
He will make $43.20 more each week.
Answer:
x=3
Step-by-step explanation:
Answer:
± 60
Step-by-step explanation:
aₙ = a₁ * rⁿ⁻¹
a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶ (1)
a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴ (2)
(1)/(2): 30/120 = 1/4 = r²
r = ± 1/2 or ± 0.5
a₁ = a₇/r⁶ = 30/0.5⁶ = 1920
a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60
