An angle is two rays with a common endpoint, called the vertex. The rays are the sides of the angle.
In the angle ∠XYZ, the vertex is Y, and the sides are rays 
and 
You can name angles by three letters, X on one side, the vertex Y, and Z on the other side: ∠XYZ and ∠ZYX are both names for this angle. Or an angle can be named by just its vertex, for example, ∠Y, as long as it is the only angle with that vertex.
Therefore, the correct option is B
Answer:-2/5
Step-by-step explanation:
Now the above equation can be rewritten as 5y= -2x+1
Dividing this expression through by 5, we have 5y/5 = -2x/5 + 1/5
y= (-2/5)x + 1/5
Comparing with the general equation of a line;
y = mx + c; m= gradient; C= constant along the y-axis
m= -2/5
Answer:
C
Step-by-step explanation:
If you fill in x=0, you are left with the y intercept. In the picture you can see it must be larger than y=10. This invalidates answer A and D.
The x-coordinate top of the parabola ax²+bx+c=0 is given by y = -b/2a, so immediately we can see -b has to be positive. This leads you to answer C because -9x implies b=-9, and --9 is positive.
