10. A student studied 18 hours in 7 days, if he wants to study average 2 hours each day 14 days. How many hours he needs to study for next 7 days!

Please show step by step breakdown

HE WILL HAVE TO STUDY 10 HOURS

Step-by-step explanation:

[(2 hours)/(1 day)](14 days)=(18+x)hours

Let's note that the unit of day is in the numerator and denominator.  It cancels

[(2 hours)/(1 day)](14 days)=(18 hours)+(x hours)

(2 hours)(14)=(18+x)hours

Let's note that the unit of hours is in the numerators of both sides of the equation.  It cancels

(2 hours)(14)=(18+x)hours

(2)(14)=18+x

28=18+x

10=x

answer: the answer to your question is parallel

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
