algol [13]

Answer:

32d

Step-by-step explanation:

-The students ride their bikes to and from school every day. The distance is thus;

d_t=2d

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

Days=Days \ per \ week \times \ number \ of \ weeks\\\\=(5-1)\times 4\\\\=16\ days

Now, we multiply the distance per day by the total number of days:

Distance, D=2d\times 16\\\\=32d

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).

Given f(x) - 3x= 1 and g(x) - 2x-3, for which value of x does g(x)= f(2)?
alexira [117]

Answer:

Best Answer:  f(x) = 3x - 1, g(x) = 2x - 3

f(2) = 3(2) - 1 = 6 - 1 = 5.

2x - 3 = 5

2x = 8

x = 4. This value ensures g(x) = f(2).
