Answer:

Step-by-step explanation:

For this question you can say d = 15 feet so we need the t then you can say :

15 = l 130 - 25t l ⇒ because of the absolute value you should say :

1) 130 - 25t = 15 ⇒ -25t = 15 - 130 ⇒ - 25t = -115 ⇒ t = 115/25 = 4.6 sec

2) 130 - 25t = - 15 ⇒ -25t = -15 - 130 ⇒ -25t = - 145 ⇒ t = 145/25 = 5.8 sec

so the answer is c :))

i hope this is helpful

The cost of parking in a garage, in dollars, can be modeled by a step function whose graph is shown. How much does it cost to pa

S_A_V [24]

Answer:

the cost is $\$6$

Step-by-step explanation:

observing the graph

we know that

For the interval of x------> $(0,1]$ -----> the cost is $\$0$

For the interval of x------> $(1,3]$ -----> the cost is $\$4$

For the interval of x------> $(3,4]$ -----> the cost is $\$6$

For the interval of x------> $(4,infinite)$ -----> the cost is $\$10$

In this problem we have

$3$ hours and $45$ minutes

therefore

the value of x belong to the interval $(3,4]$

the cost is $\$6$

Solve the inequalities by graphing. Select the correct graph. y > 2x y < 3

Kryger [21]

The solution of the first graph is 1, 2 while the second graph is a straight line.

<h3>How to solve for the graph</h3>

We have y > 2x

y< x

First you have to replace the inequality by a mathematical operator

y - 2x = 0

y - 3 = 0

equation 1 is of the form

y = mx

The slope here is 2,

to make a graph we need to have x = 1 then the line would pass through

(1,2).

The second equation is simply a second line that would pass through the x axis.

The correct graph is below:
