Aaron mowed 7 lawns in 4 hours. At that rate, how long will it take him to mow 21 lawns?

12 hours

Step-by-step explanation:

So, 7 times 3 is 21. This means he have to multiply 4 by 3 to get 12.

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
