Inverse variation is of the form:
y=k/x, which we can express as:
yx=k we are given the point (2/3, 7) so we can solve for k
7(2/3)=k
14/3=k
y=14/(3x), so when x=7/3
y=(14/3)/(7/3)
y=(14/3)(3/7)
y=2
Answer:
B 10/26
Step-by-step explanation:
Cosine is the adjacent side over the hypotenuse.
Answer: 5y
Step-by-step explanation:
Product means the multiplication of, so taking the product of 5 and y we simply have;
5*y=5y
Harrison is correct because the 305 in the actual problem is greater than the 300 in the estimate and 57872 is less than 60000. Harrison arrived at his prediction by rounding to the nearest ten thousand and nearest hundred.
It helps you multiply by two by giving you the answer to the expression.
Example: 2•5=10/
