In a JSS 1 class, 10 girls study Music and 15 girls study Fine art. Altogether 20 girls study Music or Fine art (or both). Draw a Venn diagram and find out how many girls study both subjects. In a class of 40 student 25

80 the answer is 80

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.

step-by-step explanation:

i think it's b. 5.5

step-by-step explanation:

because if you subtract 2 from 7.5 that's what you

hope that . i might be wrong though =i
