Answer:
0.25 (inches?)
Step-by-step explanation:
the equation is:
y=mx+b
y is the length of her hair, the dependent variable, the outcome
m is the slope, which is in this case the growth of her hair in a month
x is the independent variable, or the number of months
b is how long her hair is to start with, which is 12 in
we are looking for m, which is the growth of her hair per month, which is given as 0.25 inches, so that would be the answer
Answer:
In total 177 more students enrolled this year.
Step-by-step explanation:
First get the sum of the students who enrolled in 1995, then the sum of 2005 and then subtract the sums.
1) add.
for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3
2) subtract
for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3
3) change
for example 3 - (- 2) = 3 + 2
4) -10
the sum is -10.25, which is closest to -10
First, solve the parenthesis
Remember to follow PEMDAS, and the left-> right rule
12/3 = 4
4 x 2 = 8
8 + 3 = 11
11 - 7 = 4
Square the remaining number
4² = 4 x 4 = 16
16 is your answer
hope this helps
