Step-by-step explanation:
100= -25h+5h
100=-20h
d.b.s by 20 to make h the subject
100/-20 = -20h/-20
h= -5.
What is the absolute value of the number indicated on the number line below?B.
8
D.
9
it can be either b or d
if your trying to find the absolute value for -8 then its b
if your trying to find the absolute value for -9 then its d
Yes
Set the total cost toy, the number of books is x.
So, y= 200+2x
so cost is a dunction of the number of books
Hope this helps you!!!!! :D
When something says 'solve for the system of equations' they are looking for a point where the graph of the two functions intersects. Since they give you the graph, the two functions approximately intersect somewhere between the x-value of -6 and -7 (i.e. -6.5) and somewhere between the y-value of -3 and -4 (i.e. -3.5). So, the closest estimate is (-6.5, -3.5) or A.
The numbers are irrational, so I can't write them exactly with digits.
When rounded to the nearest ten-thousandth, they are
31.3746
and
-6.3746 .
