The answer would be 0.3 * 15 = 4.5
Answer:
b = 65
Step-by-step explanation:
b is the y- intercept
if you start to graph 6x from the two points that are already given then it'll find the y-intercept which is b
here's the graph
Answer:
<h2>x=2</h2><h2>y=4</h2>
Step-by-step explanation:
5x-y=6
2x+y=8
add them up
7x=14
divide by 7 to get x
x=2
fit it into both equation
y=4
This is an exponential decay problem.
Using the equation Y = a *(1-rate)^time
where Y is the future value given as 12,000 and a is the starting value given as 13,000.
The rate is also given as 5%.
The equation becomes:
12,000 = 13,000(1-0.05)^x
12,000 = 13,000(0.95)^x
Divide each side by 13000:
12000/13000 = 0.95^x/13000
12/13 = 0.95^x
Use the natural log function:
x = ln(12/13) / ln(0.95)
x = 1.56 years. ( this will equal 12,000
Round to 2 years it will be less than 12000.
