The table below shows the elevations at which the different artifacts were found during an archeological dig. a) Write the name of each artifact and the elevation at which each artifact was found using a positive integer, zero, or negative integer.
b) Explain how you determined if an elevation required a postivite integer, zero, or a negative integer.
( I have to find the mistake to the student's work to these questions )
Students work:
a) arrow head=+15
bone=+721
clay bowl=0
necklace=-462
woven basket=-1,200
b) 'by the text telling me below or above sea level. 0 meant on sea level
(PLEASE HELP IM DESPERATE, sorry for having such a large question)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
