Answer:

2.25km

Step-by-step explanation:

Calculate the total distance:

<u>9km/</u> 0.80 x 100% = 11.25km

 

The walker has travelled 9km, so

11.25km - 9km = 2.25km left

Which is the graph of y=[x]-2?
STatiana [176]

Answer:

The function y = ⌊x⌋ is called the "greatest integer value" function.

it works as follows: the input is any number x, the output is the greatest  

integer smaller or equal to x.

For example:

⌊0.1⌋=0

⌊0.26⌋=0

⌊0.4678⌋=0

⌊0.8989⌋=0

⌊0.999⌋=0

⌊1⌋=0

⌊1.0001⌋=1

so, the value of ⌊x⌋, for the entire interval (0, 1] is 0.

Similarly,  

the value of ⌊x⌋, for the entire interval (1, 2] is 1.   and so on,  

thus the graph of  y = ⌊x⌋ is as shown in picture 1

the graph of   y = ⌊x⌋ – 2   is the graph of   y = ⌊x⌋   shifted 2 units down.

check picture 2.

Help please 10 minutes!!!!!!!!!
WITCHER [35]

Substitute y = 2x - 15 to the second equation:

4x + 3(2x - 15) = -5      use distributive property

4x + (3)(2x) + (3)(-15) = -5

4x + 6x - 45 = -5       add 45 to both sides

10x = 40      divide both sides by 10

x = 4

Substitute the value of x to the equation y = 2x - 15:

y = 2(4) - 15 = 8 - 15 = -7

<h3>Answer: (4, -7)</h3>

-<br> Use the order of operations to simplify 4(3.5 - 1.5) -
irinina [24]

Answer:

When simplified this equation equals 8.

Step-by-step explanation:

Let me show you my work.  

4 ( 3.5 - 1.5 ) = 4 ( 2 )

4 ( 2 ) = 8 because 4 times 2 = 8

Hope this helps. . .
