F (x) =3(x-2) given that f(t) =6, find t

lina2011 [118]

Answer:

$\qquad{:}\longrightarrow\tt f (x)=3 (x-2)$

$\qquad{:}\longrightarrow\tt f (t)=3 (t-2)$

$\qquad{:}\longrightarrow\tt f(t)=6$

$\qquad{:}\longrightarrow\tt 3 (t-2)=6$

Simplify

$\qquad{:}\longrightarrow\tt 3t-2=6$

$\qquad{:}\longrightarrow\tt 3t=6+2$

$\qquad{:}\longrightarrow\tt 3t=8$

$\qquad{:}\longrightarrow\tt t=\dfrac{8}{3}$

$\therefore\sf t=\dfrac{8}{3}$

A)Jodis car used 12 gallons of gas to travel 456 miles. how many miles did her car travel per gallon of gas? show your work.

Tresset [83]

a) Jodi's car traveled 38 miles per gallon of gas. We know this because by dividng the amount of miles traveled by number of gallons Jodi has in her car we can find how many miles she travels per gallon of gas.

So our equation would be 456 / 12 = 38

b) The cost per gallon of gas was $3.74. We can find this answer by dividing how much she paid ($44.88) by how many gallons she bought (12).

So our equation would be 44.88 / 12 = 3.74

Where did we get one?

77julia77 [94]

Answer:

The -1 came from factoring.

The equation is multiplied by 8 because 8 could be pulled from 16x-8.

16 can be divided by 8 2 times and 8 can only divided by 8 once.

so factoring it makes the equation 8(2x-1)
