Answer:
x+y=15
Step-by-step explanation:
Given equation of 
Differentiating both side 

It passes through the point (12,3) so

So equation of tangent passing through (12,3) is
as 
So x+y =15 will be the equation of tangent which passes though the point (12,3)
Answer:
28 degrees
Step-by-step explanation:
hi! since m<ABC is 175 degrees and m<YBC is 147 degrees, we can subtract these to find m<ABY.
175-147= 28 degrees
Which set of numbers correctly shows all of the factors of 28? 1, 2, 4, 7, 14, 28 1, 2, 7, 14, 28 0, 1, 7, 14, 28 1, 2, 4, 7, 8,
slega [8]
Answer:
1, 2, 4, 7, 14, 28
Step-by-step explanation:
Factors of 28 are the numbers that divide into 28 evenly.
1, 2, 4, 7, 14, 28
Z-12=6
you take the 12 and add it to both sides making it look like:
z-12+12=6+12
which also looks like
z-0=6+12
z-0 = z
so now you have
z=6+12
6+12 = 18
SO Z=18!!!
your answer is 18
Answer: 2 bookcases.
Step-by-step explanation:
Let be "x" the number of bookcases that the custodian will be able to repaint completly with 5 gallons of paint.
According to the data given, the custodian needs 2 gallons of paint to repaint one bookcase. Since all the bookcases are equal, you can set up the following proportion:

Now you must solve for "x" in order to find its value:

Notice that the custodian will be able to repaint 2 bookcases completely, then you can say that:
