The function y=12x when plotted using the interval of
x-values from -1 to 3 will give a straight line on a given plot. Therefore the
function rule of a line y=mx+b can be used to describe the growth or
progression of this function. The rule states that y is directly proportional
to x.
248/4 = 62
to check if you are right
you do
62*4= 248
or you can do
248/62= 4
You can check in both way
A)
X/3 -2 = 6
Add 2 to both sides:
X/3 = 8
Multiply both sides by 3:
X = 24
B)
X/5 +1 = 5
Subtract 1 from both sides:
X/5 = 4
Multiply both sides by 5:
X = 20
Answer:
The amount of interest earned at the end of 14 years would be $672.3486
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this problem, we have that:

So

The amount of interest earned at the end of 14 years would be $672.3486
Answer: 130 degrees
Step-by-step explanation:
105+80+45+x=360
230+x=360
-230 both sides
X=130 degrees
