<span><span /><span>The answer to that problem is 813. When you are given a problem like this, you can answer it by using the MDAS technique. MDAS stands for multiplication, division, addition, and subtraction. Since you are following the MDAS technique, you are asked to answer the equation based on MDAS order. To put this simply, look at the example below:

     20x40+3x9/3+4
     800+3x9/3+4
     800+27/3+4
     800+9+4
     809+4
     813</span></span>  

You can clearly see the MDAS order by following the bold text.

Multiplication and division must be done before addition and subtraction. Therefore:

(20×40)+(3×9÷3)+4
=800+9+4
=813

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.

What is the x intercept for y=(2x(x-3))/(x-1). ?
Ainat [17]

Answer:

( 0,0) and (3,0)

Step-by-step explanation:

y=(2x(x-3))/(x-1)

Set y = 0

0 =(2x(x-3))/(x-1)

Multiply each side by x-1, which makes x not equal to 1

0 =(2x(x-3))

Using the zero product property

2x=0  x-3 =0

x=0   x= 3

The x intercepts are x=0   x= 3

( 0,0) and (3,0)
