No because that would just be measuring freshman a better sampling method would be surveying the same number of students for each grade
The equation would look like
Y=-4x+7
Y=mx+b
Answer:
Step-by-step ef(x)=-2x+5……i
and f(-3x)=?
let x=-3x so that
-2x+5=-3x
x=5
substitutinx x into… i
f(x)=-10+5=-5
f(5)=-5………ii
now f(–3x)=f(-15)
scrutinizing… ii ,we can propose that
f(-15)=15.
Thus f(-3x)=15xplanation:
Y=mx+b
m=slope
given
y=6x-9
m=6
the slope is 6
