Joan, s age is triple the age of her daughter. if joan is 42 years old, how old is her daughter

42 is 3 times 14.

Joan's daughter is 14 years old.

If you know your times tables, you know 42 = 6·7. Since you're familiar with the associative property of multiplication, you know you can regroup the factors of this:

... 42 = 6·7 = (3·2)·7 = 3·(2·7) = 3·14

Of course, you can always simply divide 42 by 3 using your calculator or even long division.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
