Answer:
b. distributive property
c. commutative property
e. subtraction
f. division
Step-by-step explanation:
These are the steps you use to solve algebraic equations.
B is the answer I think it’s close though
Answer:
-| y | ≤ | -y |
Step-by-step explanation:
-| y | will be non-positive (may include 0). |-y| will be non-negative (may include 0). A non-positive number is always less than or equal to a non-negative number. They are only equal when both are zero.
Answer:
<em>y</em> = 6
Step-by-step explanation:
The red square represents a 90 degree angle. If you subtract 36 from 90 you will get 54. Then to find <em>y</em>, divide 54 by 9 and you get 6.
Hope this helped!! :)
Answer:
a) (-9, +∞)
b) [8/3, +∞)
Step-by-step explanation:
a) 6x - 5 < 7x + 4
We need to write the terms with x on one side and the terms without x on the other side
6x - 5 < 7x + 4
-5 - 4 < 7x - 6x
-9 < x
Therefore x >-9, in set notation this would be (-9, +∞)
b) x² + 3(x - 1) ≥ x² + 5
We need to solve first the parentheses and combine like terms
x² + 3(x - 1) ≥ x² + 5
x² +3x -3 ≥ x² + 5
x² - x² + 3x ≥ 5 + 3
3x ≥ 8
x ≥ 8/3
Therefore, the solution in set notation would be [8/3, +∞)
