Answer:
y = −32
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = -1
Step-by-step explanation:
combine like terms on both sides (like terms refers to the variable, x in this case) so
3x + 7 = 11x + 15
then get x terms to one side and non-x terms to the other
this gives you: 7 - 15 = 11x - 3x
-8 = 8x
dived both sides by 8 (since its the constant with x) which gives you
x = -1
hope I could help ( I messed up at first but I fixed it)
There follows the formula for "z-score:"
raw score - mean
z = ------------------------------
standard dev
9.1 - 8
Here, the z-score is z = ------------- = 0.344
3.2
Answer:
Consider the segment on the right.
collinear points
If 3 points A, B, and C are collinear and B is between A and C, then
