Inverse variation:
k is a constant
Use the given information (when x=4 y=4) to find the value of the constant:
Then, the given relationship has the next equation:
Use the equation above to find y when x=2:
Then, when x=2, y=8
Answer:
Step-by-step explanation:
function: all the points
note: x intercept is the domain, y intercept is the range
domain must paired with exact range
the domain can be more than 1, but range must be 1.
domain : 3, 5, 0 , -1, -3, -5
range: 1, 3, 4 , -3(there is 2 but we write it one) , -4
and done!
thank you!
Answer:
189
Step-by-step explanation:
You take 63% make it a decimal by dividing it by 100 and then you multiply it with 300. 300*.63=189.
Answer:
a set of two or more equations, each containing two or more variables whose values can simultaneously satisfy both or all the equations in the set, the number of variables being equal to or less than the number of equations in the set.
Step-by-step explanation:
It works because of two properties of equations: Multiplying (or dividing) the expression on each side by the same number does not alter the equation. Adding two equations produces another valid equation: e.g. 2x = x + 10 (x = 10) and x − 3 = 7 (x also = 10).
