Answer:

(\frac{2}{3} , \frac{1}{5})

Step-by-step explanation:

The fastest way to do this is to convert both equations into slope-intercept form and graph it to find the solution point. If you wanted to do this algebraically, you might want to start out by getting rid of the fractions and using either substitution or elimination to find x and y.

You can invest $200 at 8% for 3 years. Find the simple interest.
Ira Lisetskai [31]

Answer:

$48

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

then, solving our equation

I = 200 × 0.08 × 3 = 48

I = $ 48.00

The simple interest accumulated

on a principal of $ 200.00

at a rate of 8% per year

for 3 years is $ 48.00.

Since the Great Recession of 2007–2009.
vaieri [72.5K]

Answer: C

The movement of the unemployment rate and inflation rate has been inconsistent with a stable Phillips Curve

Step-by-step explanation:

The Phillips curve is an economic model suggesting a negative relationship between the unemployment rate and inflation. The model, therefore, implies that a fall in unemployment should lead to an increase in inflation. However, there is a doubts among economists about whether the Phillips curve is an appropriate model to forecast inflation. The doubt is based upon the issues which presented itself during, and after, the Great Recession. During the Recession, the U.S faced a rise in the unemployment rate and according to predictions from the Phillips curve, the rise in the unemployment rate should have yielded a greater decrease in inflation. Much greater than the decrease the U.S. experienced. It

seems like the relationship between inflation and unemployment, once regarded reliable, has weakened. Researchers have been trying to understand why inflation has been behaving in this way.

How do you write 5x - 4y = 1 in slope intercept form
Alexxandr [17]

First move the 4y to the right and the 1 to the left:

4y=5x-1

Then divide everything by 4:

y=5/4 x - 1/4
