Answer-
y = -1x or y = -x
Explanation-
Step 1: Look for a pattern in the x column and the y column.
X = -1, 3, 7, 11
(The pattern is that you add 4 with every number)
Y= 0, -4, -8, -12
(The pattern is that you subtract 4 with every number)
Step 2: Create and (if needed) simplify the slope
Slope = y/x
Slope -> -4/4
Simplified Slope -> -1
Step 3: Put it in slope-intercept form
Slope-intercept form -> y = mx + b
y = -1x + 0 -> y = -1x or y = -x
Answer:
Every one out of 125 people got a mild allergic reaction or 0.8%
Step-by-step explanation:
64/8000 simplified by 8 is 8/1000 simplified by 4 is 2/250 simplified by 2 is 1/125
A) Now look, in the year 2000, the population is 118,000
In the year 2006 is 138,000
To find the percent change |Original Amt - New Amt| -------------------------------- x100
Original Amt
So for this question you would do 118,00 - 138,000 (ignore the negativesss)
and you get -20,000 (ignore the negatives) and then you get 20,000
Now, you have to do 20,000 divided by 118,000 x 100
20,000 divided by 118,000 and you get 0.169491525
Now you have to multiply 0.169491525 by 100
0.169491525 x 100 = 16.9491525
Round this and you get a 16.9% change.
b) To predict the population in 2012 you will have to do 138,000 + 16.9%
To calculate this you have to do this:
138,000 x 0.169 = 23322
Now add 23,322, to 138,000 and you get 161,322.
A) 16.9%
B) 161,322
hope this helped :)
Answer:
a^8 - 12a^4 + 36
= (a^4)^2 - 2*a^4*6 + 6^2
= (a^4 - 6)^2
Answer:
a 16
Step-by-step explanation:
16 x 12 = 192 plates
496 total plates - 192 = 304
304 packages of 8 plates
304 / 8 = 38 sets of 8 plates
38 + 16 = 54 packs of plates
