Answer:
<u>Answer</u><u>:</u><u> </u><u>4</u><u>x</u><u>²</u><u> </u><u>-</u><u> </u><u>9</u><u>x</u><u> </u><u>+</u><u> </u><u>2</u><u>0</u><u> </u>
Step-by-step explanation:
• General quadratic equation:

• sum of roots → 4 + 5 = 9
• product of roots → 4 × 5 = 20
• substitute:

-2xy+3x-2xy+3x
-2xy-2xy+3x+3x ( combine like terms)
-2xy-2xy=-4xy
3x+3x=6x
-4xy+6x
Answer: B. -4xy+6x
You will multiply and combine similar variables using the rules of exports making the answer D: x^6
Answer:
The y intercept is 1/2
i.e. The starting height is 1/2
Step-by-step explanation:
Given

Required
Determine the y intercept --- <em>Missing</em>
At y intercept: 
So:

Substitute 


<em>The y intercept is 1/2</em>
10 ^ -3 = 0.001
10 ^ -2 = 0.01
10 ^ -1 = 0.1
10 ^ 0 = 0
10 ^ 1= 10
10 ^ 2 = 100
10 ^ 3 = 1000
