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:
0
Step-by-step explanation:
You first multiply -2(-2) which will be 4 since a negative times a negative is a positive. Next you subtract 4 and -4 which is 0. Lastly you bring down the y which is equal to 0.

Answer:
Jo's thinking about the number 20.
Step-by-step explanation:
9x-4=176
9x=176+4
9x=180
x=180/9
x=20
Answer:
m = 3/2
b = -3
Equation:
y = 3/2x - 3
Step-by-step explanation:
m = rise/run
rise = 3
run = 2
b = y-intercept
y-intercept is -3
Equation: y = mx + b
y = 3/2x + (-3)
y = 3/2x - 3
