Answer:
Step 2: Commutative Property
Step 3: Associative Property
Step-by-step explanation:
According to the Commutative Property of Addition: Two real numbers can be added in either order.
a + b = b + a
Therefore, she used the Commutative Property in Step 2.
In Step 3, she used the Associative Property, in which the grouping of the addends does not change the sum.
An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i² = −1. The square of an imaginary number bi is −b². For example, 5i is an imaginary number, and its square is −25
Answer:
-1
Step-by-step explanation:
Formula: 
<u>Using two points:</u>
Since we are given the 
and 
value, what is left is the 
and 
in the formula, which represent slope and the y-intercept.
<u>Slope</u>
is slope
Formula: 
Plug points: 
Solve: 
Simplify: 
Therefore, the slope is -1

<u>y-intercept</u>
is the y-intercept
Plug one of the points and the slope into the formula, solve for b: (4, 3)
Answer:
140
Step-by-step explanation:
5%/100 = 7/?
7 times 100 = 700
700 divided by 5 = 140 coins
