An exponential behavior can be observed.

Let x be the number of years she has to wait.

100((1+0.08/12)^12x) = 150

Now solve for x.

log base 1.08/12 of 1.5 = 61.02 approx

12x=61.02

x=5.09 years

Jordan wrote the following description. Three fewer than one fourth of x is 12. Write an equation to represent the description??

VMariaS [17]

Answer:

1/4x - 3 = 12

Step-by-step explanation:

When it says "three fewer," it means subtract three from one fourth of x. "Is" always means the equal sign. Knowing this, we get the equation:

1/4x - 3 = 12

Write the standard form of the line that contains a slope of -1/2 and y-intercept of 1. Include your work in your final answer.

NemiM [27]

The slope intercept form would be y= -1/2x + 1 and to get it into standard form all you have to do is move the -1/2 x to the other side, making it 1/2x + y = 1
