Answer:

A : 20x+21=30x-29

B : m<1 = 121 m<2 = 121

Step-by-step explanation:

Original equation

20x+21=30x-29

Add +29 to both sides

20x+50=30x

Subtract -20x

50=10x

Divide by 10

5 = x

Checking your work and doing substitution

20(5)+21

100+21

121

30(5)-29

150-29

121

Answer:

an = -6n + 5.

Step-by-step explanation:

This is an arithmetic sequence with first term a1 = -1 and common difference d = -6

an = a1 + d(n-1)

an = -1 + -6(n - 1)

an = -1 -6n + 6

an = -6n + 5.

F(x) = 4/x-9<br> g(x)=4/x + 9<br> find f(g(x))

Alenkinab [10]

Hello,

$f(x)= \dfrac{4}{x-9} \\

g(x)= \dfrac{4}{x+9} \\

f(g(x))=f( \dfrac{4}{x+9} )\\

= \dfrac{4}{ \dfrac{4}{x+9}-9} \\

= \dfrac{4(x+9)}{4-9x-81} \\

=- \dfrac{4x+36}{77x+9x}
