Step-by-step explanation:
Below is an attachment containing the solution.
3.4% in decimal form is .034 = r
2014 - 2004 = 10 years = t
A = 45,000(1+.034)^10
A= 62,866

Answer:
81 miles
Step-by-step explanation:
378/14=27
The unit rate is 27 miles per hour
27*3 = 81
Answer:
when x = 7, y = 21
Step-by-step explanation:
This is about direct variation. If y varies directly with x, then there is a constant factor of variation, k. The constant of variation can be found by ʸ⁄ₓ
k = ʸ⁄ₓ
k = ¹⁵⁄₅ = 3
Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.
y = 3x
y = 3(7)
y = 21
