$10^2-48:6+25*3=100-8+75=167$

11)

$8(\frac{16}{4} )+2^2-11*3=32+4-33=3$

12)

$(\frac{6}{3} +4)^2:4*7=(2+4)^2:4*7=6^2:4*7=36:4*7=9*7=63$

13) (your answer is incorrect)

$5(9-4)^2-3^2=5*5^2-3^2=5*25-9=125-9=116$

14) (your answer is incorrect)

$5^2-2^2*4^2-12=25-4*16-12=25-64-12=-51$

15)

$(\frac{50}{5^2} )^2:4=(\frac{50}{25} )^2:4=2^2:4=4:4=1$

16)

$\frac{24+32+30+28}{2}$ -expression to represent this situation

$\frac{24+32+30+28}{2}=\frac{114}{2}=57$

Which graph shows a rate of change of 1/2 which is a fraction between –4 and 0 on the x-axis?

irakobra [83]

By definition, we have that the average rate of change is given by:

$AVR = \frac{y2-y1}{x2-x1}$

Substituting values we have:

$AVR = \frac{3-1}{0-(-4)}$

Rewriting we have:

$AVR = \frac{2}{0+4}$

$AVR = \frac{2}{4}$

$AVR = \frac{1}{2}$

Therefore, the graph that has an AVR of 1/2 is the graph of the linear function.

Answer:

graph shows a rate of change of 1/2 is the linear function

Y=f(x) = (1/2)<br> Find f(x) when x = 1

sammy [17]

The value of function on x=1 is 0.5

Step-by-step explanation:

In order to find the value of a function on given input, the input is put at the place of variable in the function.

Given function is:

$f(x) = (\frac{1}{2})^x$

We have to find the value of function on x = 1

Putting x = 1 in function

$f(1) = (\frac{1}{2})^1\\= \frac{1}{2}\\= 0.5$

Hence,

The value of function on x=1 is 0.5

maksim [4K]

Hi so I’m going to answer your problem which is “List three words or phrases used in real life that indicate positive numbers,” so let’s get right into it!

You can it as temperature too, today is 80+ degrees outside!

You can also use an the floors of which an elevator takes you in which direction it takes upwards or downwards like “take the elevator 4 floors up”

You can also use gas as a thing we use in real life, it also indicates numbers

Like gas is __ a gallon cheaper this week
