Indira and jean begin their hike at 10 am. one morning, they plan to hike from 2 2/5 mile marker to the 8 1/10 mile marker aling the trail.

The distrance to be travelled is 8/10 - 2/25 therefore:

Total dlistance = 81/10 - 12/5

add using least common denominator:

Total distance = 81 - 12 x 2

                    10

evaluate:       Total distance = 57/10 = 5.7

according to the given information if they travel at a speed of 3 miles per house and there are 12-10= 2 hours, so the distance travelled to noon will be 2x = 6 miles - 5.7 miles.  This implies that they will be able to reach the 8 1/10 mark by noon.

the answer is 4.8 units on e2020.

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
