If the graph of the parent function f(x) = x is shifted 7 units down, which of the following equations would the new graphed line represent?

Option (2)

Step-by-step explanation:

If a function g(x) is shifted 'a' units downwards then the equation of the transformed function will be,

g(x) = f(x) - a

Similarly, when the parent function is shifted 'a' units upwards, equation of the transformed function will be,

g(x) = f(x) + a

If the parent function is f(x) = x

And the graph of this function is shifted 7 units downwards,

Transformed function will be,

f'(x) = x - 7

Option (2) will be the correct option.

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

answer: i think it is (1,-2)
