Solve the system: x + y = 10 and x - y = 4. What is x?
Answer: x = 7
Adding the equations gives 2x = 14, so x = 7.
What is the simplified form of (3x²y)(4xy³)?
Answer: 12x³y⁴
Multiply coefficients (3×4=12) and add exponents: x^(2+1)=x³ and y^(1+3)=y⁴.
A store marks up items by 25%. If an item costs the store $48, what is the selling price?
Answer: $60
Selling price = 48 × 1.25 = $60.
Which of the following is a factor of x² - 9x + 18?
Answer: (x - 3)
x² - 9x + 18 = (x - 3)(x - 6), so (x - 3) is a factor.
What is the solution to |2x - 4| = 10?
Answer: x = 7 or x = -3
Set 2x - 4 = 10 (x = 7) and 2x - 4 = -10 (x = -3).
If 5x + 2y = 20 and y = 5, what is x?
Answer: x = 2
Substituting y = 5: 5x + 10 = 20, so 5x = 10 and x = 2.
What is the degree of the polynomial 4x³ - 7x⁵ + 2x - 9?
Answer: 5
The degree is determined by the highest exponent, which is 5 in -7x⁵.
