9. Mary was 23 years old when her daughter was born. The product of the ages now is 174. Find the ages of Mary and her daughter

mary should be 29 while her daughter 6.

Product means the number that you get to by multiplying two or more other numbers together. so when u multiply 29 and 6 u get 174.

Mary is 29 and her daughter is 6

Step-by-step explanation:

when Mary was 23, her daughter was 0

                  so the product is           23 × 0 = 0

when Mary was 24, her daughter was 1

                                                          23 × 1 = 1

when Mary was 25, her daughter was 2

                                                          25 × 2 = 50

when Mary was 29, her daughter was 6

                                                          29 × 6 = 174

∴ Mary is 29 and her daughter is 6

(im sure there is a way easier method to find this ;-; but this is how i did it)

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
