Answer:
Step-by-step explanation:
The function has the vertex at .
Since , the graph of the function is a maximum graph.
The highest y-value is the y-coordinate of the vertex which is 5.
Therefore the range is {}

Answer:
-5/14
Step-by-step explanation:
2/7 times 2 to get the denominator to be 14 since adding and subtracting fractions require the same denominator. 2/7 times 2 = 4/14. -9/14+4/14=-5/14.
First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4
C is the answer because it is
