Answer:
D. Circle; (x²) + (y²)-4=0
Step-by-step explanation
Simplify the equation by dividing both sides by 2
2x² + 2y² =8
x² + y² =4
this gives a circle form where we can apply (x-h) ² +(y-k)² =r² to find center and radius of the circle.
Thus r=2, h=0, k=0
Center of circle is at (h, k), (0,0)
Radius of circle is 2
Answer:
(-2, 0)
Step-by-step explanation:
Probability is the likelihood or chance of an event occurring. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail).
X + (x+1) = 2x+1
Here, 2x+1 is always odd
For example the value of x is 2 then we can say that,
x=2; x+1=3; 2x+1 = 5 <u>[odd number(5)]</u>
= 2 + 3 = 5

Answer:
D
Step-by-step explanation:
y>-3x+1 Negative slope
y<u><</u>x+2 Positive slope
< or > have dotted line
<u><</u> or <u>></u> have a solid line
> or <u>></u> means solutions are above the line
< or <u><</u> means solutions are below the line
The one with negative slope has a dotted line and solutions above it.
The one with positive slope has a solid line and solutions below it.
