Answer:
A. y = x² - 9x + 18
Step-by-step explanation:
The key thing to look for in this graph is the <u>y-intercept</u> (where the graph will hit the y-axis).
We can't see exactly where y-intercept is, but we know it is a positive number.
In a standard form quadratic equation:
<em>y = ax² + bx + <u>c</u></em>
'<em>c</em>' tells you what the y-intercept is.
The choices with positive y-intercept are <u>A</u> and <u>B</u>.
Again, we can't see exactly where y-intercept is, but we know it is not 1.
y = x² - 9x + 18
has a positive y-intercept that is not 1,
thus the answer is A.

kilograms of yellow potatoes bought is 8330 kg
<em><u>Solution:</u></em>
Given that James buys 245 kilograms of red potatoes
He buys yellow potatoes that weigh 34 as much as the red potatoes
To find: kilograms of yellow potatoes bought by James
Let "y" be the kilograms of yellow potatoes bought
Let "r" be the kilograms of red potatoes bought
kilograms of red potatoes bought = 245 kilograms
r = 245 kilograms
From given information,
Yellow potatoes weigh 34 as much as the red potatoes
here "as much as" means product or multiplication
Kilograms of yellow potatoes bought = 34 x kilograms of red potatoes bought

Thus kilograms of yellow potatoes bought is 8330 kg
The answer cannot be expressed in mixed number since whole numbers has no fractional part
