Answer:
The answer to your question is -5k⁶
Step-by-step explanation:
Polynomial
- z³ + 5k⁶ - (-z³ + 10k⁶)
Use law of signs for the parenthesis
- z³ + 5k⁶ + z³ - 10k⁶
Use associative property for like terms
(-z³ + z³) + (5k⁶ - 10k⁶)
Simplify like terms
(0) + (-5k⁶)
Result
-5k⁶
Answer:
D
Step-by-step explanation:
We can substitute y = 2x + 1 in the second equation
2x + 1 = -7x + 8
Add 7x to both sides
9x + 1 = 8
Subtact 1 from both sides
9x = 7
x = 7/9
Substituing x in the first equation
y = 14/9 + 1
x rounds to 0.8
y rounds to 2.5
Let $x be the amount of money which Kelci has raised. <span>Brianna has raised 3 times more money than kelci, then she has raised $3x. Totally both have aised $(x+3x)=$4x.
</span>
Since <span>together they have raised more than $300, then 4x>300,
</span>

.
Answer: the <span>inequality </span><span><span>

</span>can be used to determine the amount of money kelci has raised</span>
Try 1(18) / 2
Just multiply 1 by 18 and divide 18 by 2.
Then we have 9!
