The sum of a number and 5 is tripled then lessened by 15 to get 9

x = "a number"

:

Just write an expression for each phrase:

:

"sum of a number & 5 is tripled",

3(x+5)

:

"the result"

=

:

"1 less than twice the number"  

2x - 1

:

Put is all together to form an equation and solve it:

3(x+5) = 2x - 1

:

3x + 15 = 2x - 1

:

3x - 2x = -1 - 15

:

x = -16

:

:

Now in the original statement see if that is true

"the sum of a number and five is tripled, the result is one less than twice the number"

3(-16+5) = 2(-16) - 1

3(-11) = -32 - 1

-33 = -33; equality confirms our solution of x = -16

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
