Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using function notation?
O MY = - van
O f() = - 3x + 4
O f(x) = - *x+
O fly) = -3y+ 4

Asap (explain how you got it as well for brainliest)i tried 1: 2 and 2: 3 and they were wrong.picture of figure: in the figure below, the segment is parallel to one side of the triangle. the ratio of 12 to y is1: 21: 31: 42: 3

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60

If you have the following equation, 2/3x+5/6-x=2-3/4x what would you multiply each term by to get rid of all the fractions
