The correct answer is false the order should be
Step 1
Step 3
Step 5
Step 2
Step 6
Step 4
Step 7
Try them and see.
For the first:
3(-3) + 0 = -9 . . . . not > -8
3(-2) + (-1) = -7 . . . is > -8 . . . . . 2) (-2, -1) is a solution
For the second:
4 - 4(-2) = 12 . . . . not ≤ -6
-2 -4(1) = -6 . . . . . is ≤ -6 . . . . . . 2. (1, -2) is a solution
Answer:
The slope is the percentage of test score per number of days absent
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to

we have
y -----> is the percentage of test score
x ----> is the number of days absent
so
That means -----> The slope is the percentage of test score per number of days absent
In this problem the slope is negative
so
If the percentage test score increases----> the number of days decreases
If the percentage test score decreases----> the number of days increases
It's 8...................................
Have you considered applying the Law of Cosines?
For angle B: b^2 = a^2 + c^2 - 2ac*cos B
a, b and c are all known, leaving cos B as the only unknown. Find cos B, and then find angle B itself. From the diagram we know that angles A, B and C are all acute.
