Answer:
b. ellipse
Step-by-step explanation:
The squared terms have the same sign and different coefficients. That means the equation describes an <em>ellipse</em>.
__
<em>Additional comment</em>
<em>both variables are highest degree 2</em>:
coefficients have the same sign and magnitude: circle
coefficients have the same sign and different magnitude: ellipse
coefficients have different signs: hyperbola*
<em>only one variable has highest degree 2</em>:
parabola
____
* If the equation can be factored to a product of linear terms that is zero, then the equation is of two intersecting lines. This is a degenerate case of the hyperbola in which the major axis is zero: the two vertices are the same point.
Answer: 2 m/s
Step-by-step explanation:
The position time graph shown above has position or distance on the vertical axis and time on the horizontal axis. The unit of the distance is in metes and the unit of the time is in seconds.
Distance = velocity / time
Time = distance × time
From the graph, the slope at any point determines the velocity of the object at that point.
Slope =( y2 -y1)/ ( x2 -x1)
y2 = 5(corresponding to the point on the vertical axis where t = 2.5 on the horizontal meets the plotted line when traced along the vertical axis)
y 1 = 0 (initial distance)
x2 = 2.5( on the horizontal axis)
x1 = 0(initial time)
Velocity = slope = (5-0)/2.5-0)= 5/2.5
= 2 m/s
Answer:
y = -3x - 1
Step-by-step explanation:
y = mx + c
m = (-4-2)/(1-(-1)) = -6/2 = -3
y = -3x + c
When x = -1, y = 2
2 = -3(-1) + c
c = 2 - 3 = -1
y = -3x - 1
Can you explain what exactly you need to do because I know how to do this but I need more context
