Answer:
April took out a loan of $600 and paid it back with simple interest of $60 after 5 years. The formula to calculate interest is given the principal and the time and the interest rate is . For this problem we have to find the interest rate given . To archive that , we can just solve the equation making the interest rate the subject of the formula as shown below,
I= Prt
=> r= I/Pt
=> r= 60/600x5 = 1/50
The interest rate is 1/50 or 0.02 as a decimal. The interest rate is 2% as a percentage.
Answer:
-7
Step-by-step explanation:
Given

Required
The first difference
To do this, we simply calculate the difference between the consecutive y-values.
i.e.

So, we have:




<em>Hence, the first differences are -7 (all through)</em>
Answer:
x = 0.5, one solution
Step-by-step explanation:
6+1 = -6x + 10
7 = -6x + 10
-3 = -6x
6x = 3
x = 3/6
x = 1/2
x = 0.5
Answer:
A is the only solution.
Step-by-step explanation:
A simple way to solve it is to plug in the x and y values
For A, we plug in 2 for x and 3 for y
3-3=5(2-2)
0=5(0)
0=0
Ordered pair A is a solution
For B, plug in 3 for x and 2 for y
2-3=5(3-2)
-1=5(1)
-1 does not equal 5
Therefore only A is a solution
