32. A student is in the process of solving an equation. The original equation and the first step are shown
below.
Answers
Answer:
Step-by-step explanation:
The student used the commutative property of addtion on the right hand side, which is correct because reordering the addends doesn't affect the value of the expression.
The student used additive commutative property for the first step.
What is an additive commutative property?According to this property, when two numbers or integers are added, the sum remains the same even if we change the order of numbers/integers. This property is also applicable in the case of multiplication. It can be represented as; a + b = b + a.
The student used a + b = b + a
3a + b = 2 + 7 - 5a = 2 - 5a + 7
Because add two numbers, exchange the position of the addend, and sum of them remain same.
This is a additive commutative property.
Hence, the student used additive commutative property for the first step.

Is the equation y=5x+1 a linear equation? Explain.
Answers
Answer:
Yes
Step-by-step explanation:
Linear equations are equations in which the highest power of the equation is always 1, they look like a straight line when put on graph and they usually have this form: y = ax + b
y = 5x + 1 is a good example of a linear equation but they may also look like: y = 2x (b = 0) or y = x + 3 (a = 1).
