HELP PLSSS THIS IS HARD SOMEONE

f(x,y)=(3x,3y)

Step-by-step explanation:

Dilation with the centre at the origin with scale facor k,

= f(x,y)--->f(kx,ky)

When k=3,

f(x,y)>f(3x.3y)

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
