Answer:
$1417.5
Step-by-step explanation:
Given data
Principal=$4500
Rate = 9%
Time=3.5 years
The simple interest is given as
SI=PRT/100
substitute
SI= 4500*9*3.5/100
SI= 141750/100
SI= $1417.5
Hence the simple interest is $1417.5
Answer:
Option A
Step-by-step explanation:
I used a graphing tool to graph the equations given. When graphed, the lines intercept at (-2,3). Therefore, it is the solution to the system of equations. See the picture attached for the graph.
Option A should be the correct answer.
Answer:
Let's solve your equation step-by-step.
1/2x + 2 = −2
Step 1: Subtract 2 from both sides.
1/2x + 2 − 2 = −2 −2
1/2x = −4
Step 2: Multiply both sides by 2.
2 * (1/2x) = (2) * (−4)
x= −8
