The exponential function in the graph shows the value, in dollars, of an investment over time. what real-world information is given by the point (1, 142.50)? question 7 options: the value after 1 year the starting value the value after 142.50 years the amount of time it takes for the value to decrease by one-half

The x axis gives the time and the y axis gives the value of the investment.

x = 1, x = 2, x = 3 means the value of the investment after 1 year, 2 years, 3 years, respectively.

The point (1, 142.50) tells us the value [ y value = 142.50 ] of the investment after 1 year [ x = 1 ].

Out of the answer choices, the first one is correct.

ANSWER: "The value after 1 year"

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
