Answer:
the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)
Step-by-step explanation:
To find the points at which a graphic crosses the x-axis we need to find the values for x where y = 0.
Therefore, in the equation x²- xy + y² = 3 we are going to make y = 0 and solve for x
x² - xy + y² = 3
x²- x(0) + (0)² = 3
x² = 3
x = ±√3
x₁ = 1.73 and x₂ = -1.73
Therefore, the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)
Answer:
x+5
Step-by-step explanation:
x^2+7x+10=0
(x+5)(x+2)=0
The only factor on that list is x+5, meaning that it is the answer. Hope this helps!
Answer:
The worth of truck is $2,201 more after 2 years than after 3 years.
Step-by-step explanation:
Given: 
The value of truck is depreciate per year using above formula.
We need to find how much more worth of truck after 2 years than 3 years.
First we find the worth of truck after 2 years, put x=2 into formula


The worth of truck after 2 years would be $27,508
Now we find the worth of truck after 3 years, put x=3 into formula


The worth of truck after 2 years would be $25,307.36
Now we find difference of both value.
Difference = 27508-25307.36 = $2,201
Hence, The worth of truck is $2,201 more after 2 years than after 3 years.
