Please help- I don't know math very well :(
Vanyuwa [196]

#1

\\ \sf\longmapsto f(x)=4(x-3)

\\ \sf\longmapsto f(3)

\\ \sf\longmapsto 4(3-3)

\\ \sf\longmapsto 4(0)

\\ \sf\longmapsto 0

#2

Here

  • a_n=7n

\\ \sf\longmapsto a_{10}=7(10)=70

#3

d=1/4

a=1/4

\\ \sf\longmapsto a_4=a+(n-1)d

\\ \sf\longmapsto a_4=\dfrac{1}{4}+(3)(\dfrac{1}{4})

\\ \sf\longmapsto a_4=1

#4

\\ \sf\longmapsto y=2x-8

\\ \sf\longmapsto 2x=y+8

\\ \sf\longmapsto f(x)=\dfrac{8+y}{2}

#5

\\ \sf\longmapsto a_n=n-1

\\ \sf\longmapsto 4.5- 4(0.5)

\\ \sf\longmapsto 4.5-2

\\ \sf\longmapsto 2.5
