Answer:
Reduced price = $ ( p - 150)
Step-by-step explanation:
Let the original price of plane ticket be $p
Price reduced in plane ticket = $150
So the amount actually need to pay for a plane ticket will be given by:
Actual reduced price of plane ticket = $p - $150
i.e Algebraic expression for reduced price is:
Reduced price = $ (p - 150)

Answer f
Step-by-step explanation:
<em> x₁ = - 1</em>
<em> x₂ = 2</em>
- Step-by-step explanation:
<em>2²ˣ⁺¹ - 9ₓ2ˣ + 4 = 0</em>
<em>2²ˣₓ2 - 9ₓ2ˣ + 4 = 0</em>
<em>2ˣ = n</em>
<em>2n² - 9n + 4 = 0</em>
<em>2n² - n - 8n + 4 = 0</em>
<em>n(2n - 1) - 4(2n - 1) = 0</em>
<em>(2n - 1)(n -4) = 0</em>
<em>2n - 1 = 0 => n₁ = 1/2</em>
<em>n - 4 = 0 => n₂ = 4</em>
<em />
<em>2ˣ = 1/2 => 2ˣ = 2⁻¹ => x₁ = - 1</em>
<em>2ˣ = 4 => 2ˣ = 2² => x₂ = 2</em>
