Answer:
1. 15
2. 45
3. There is a missing digit.
Step-by-step explanation:
Given: y=3 and x= 1/2
Question 1: 4(2y-4x)-1=
- Numerical factors in this term have been multiplied.
4(6-4/2)-1
- We can reduce this fraction by dividing both numerator and denominator by a common numeric factors.
4(6-2)-1
- Numerical terms in this expression have been added.
4*4-1
- Numerical factors in this term have been multiplied.
16-1
- Numerical terms in this expression have been added.
15
Question 2: 4x^2+2y^3-10 =
4/2²2*27-10
4/2²+54-10
- We need to perform a multiplication.
- The following rule is applied:
- [tex]\frac{A}{B} C=\frac{AC}{B}[/tex]
45: Numerical factors in this term have been multiplied.
