Answer:
B
Step-by-step explanation:
the 0.1 is rate of change decreasing and 10.1 is original amount
2x + y = 8
3x - y = 17
---------------add
5x = 25
x = 25/5
x = 5
2x + y = 8
2(5) + y = 8
10 + y = 8
y = 8 - 10
y = -2
solution is (5,-2).....this is consistent and independent because it has one solution
Answer:
<em>The standard form like 
will be: 
</em>
Step-by-step explanation:
Given expression is: 
First factoring out -16 as (-1×16) , we will get....
Now, replacing 
as 
.......
Finally, simplifying the radicals in the above expression, we will get......
Thus, the standard form like will be:
Answer:
A
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
