Mike and Jeanie played 38 games of checkers. Mike won 6 more games than Jeanie. To find out how many games Jeanie won a student used this equation
M + J = 38
In this equation: M = number of games Mike won and J = number of games Jeanie won.
Which other equation would help the student to solve this problem?

30 people weigh 160 pounds or more

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

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.
