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
Answer:
They aren't equivalent
Step-by-step explanation:
Look at them as simplified fractions
4/18 = 2/9
2/12 = 1/6
If both of these are in their most simplified forms then its not equivalent!
The highest peak is in the middle and both sides of it are fairly similar, so this would be a bell shaped distribution.
Answer;
-2.5x-5
Step-by-step explanation:
first multiply whats in the () so -0.5 times 7z = -3.5z + -2 + 1z - -3
then combine like terms -3.5z + 1z = -2.5z
-2+-3= -5 so -2.5z - 5
It's many things, it's a binomial, an expression, a linear model.
