Can anyone !

jake is flying his helicopter on a trip from the airport to his secret hideout. if he flies at
140 miles per hour, the trip takes 3.2 hours. how long will the trip take if he flies at 160 miles per
hour?

t2 = 2.8 hours

Step-by-step explanation:

The distance is the same for each velocity.

Formula

d1 = d2

d = r*t

Givens

r1 = 140 miles / hour

t1 = 3.2 hours

r2 = 160 miles / hour

t2 = ?

Equation

r1*t1 = r2 * t2

Solution

140 * 3.2 = 160 * t2

448 = 160* t2

448 / 160 = t2

t2 = 2.8 hours

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
