Answer:
x < 7
Step-by-step explanation:
First apply the -2 onto each term that it is being multiplied onto.
-2x + 6 > - 8
Now subtract six from both sides.
-2x > -14
Now divide by -2.
x < 7
<u>REMEMBER</u>
When doing greater than and less than equations like this, if you divide by a negative you must flip the greater than/less than.
Put it into standard form so you would have
27x10¯6 divided by 9x10¯6
Then you can divide the numbers so 27/9 = 3
Then to divide the powers you just take them away so - 6--6 = - 6 +6 = 0
Therefore the answer is just 3
5y = 4x + 20
- 4x + 5y = 20
Answer:
Option B: 
Step-by-step explanation:
The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
