Answer:
y= 2/7x+ 43/7
Step-by-step explanation:
When finding the y intercept, or B, you should use slope intercept and plug in your coordinate. It should look like this: 7=2/7(3) +b. Multiply 3 and 2/7 to get 6/7. Now, this is your equation: 7=6/7+b. Next, subtract 6/7 from both sides to get 43/7. So, your y-intercept is 43/7. This is your final equation: y= 2/7x+ 43/7. Hope this helped!
If the interest is compounded continuously, the formula you use would look like this: A(t) = Pe^rt, where A(t) is the final amount, P is the initial investment, e is euler's number, r is the rate, and t is the time in years. Fill it in like this:
A(t) = 1600* e^(.0475)(7). Do the multiplication between the powers first:
A(t)= 1600*e^.3325. Now take e to that power to get A(t)=1600(1.3944). Finish by multiplying: A(t) = $2231.12
Answer:
70%
Step-by-step explanation:
Given data
Last years worth of vanishing potion= $82
This years worth of vanishing portion= $118
Note: Another way of asking this question is "what percent of $82 is $118"
So
=82/118*100
=0.69*100
=69%
=70% approx
Hence last years sale is 70% of this year's sales
Answer:
44 cents
Step-by-step explanation:
a unit price is how much something costs per one
if it costs 4 dollars for 9, we can do 4/9 to find the unit price
4/9=.4444444....
this to the nearest hundredth is .44 or 44 cents
