I (12) J. Hewlett invested two sums of money, but invested $1500 less at
9% than J. Hewlett did at 8%. If the income from the smaller
investment is $100 less than the income from the larger investment,
how much did J. Hewlett invest at 9% and at 8%?

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

answer: 72: 111

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
