Answer:
13
Step-by-step explanation:
We're trying to find the distance between points X and Y. Or the distance of X-Z plus Z-Y.
Lets find the distance of X-Z
6-2=4
Now lets find the distance of Z-Y
15-6=9
Now we add the distances
4+9=13
Answer:
radius
Step-by-step explanation:
From the attachment D is a point on the circumference of the circle and B is the center of the circle.
The question demands the name of line segment DB in circle B.
Any line from the center of a circle to the circumference is called a radius.
Therefore line segment DB is a radius.
The second choice is correct.
Answer:
.5
Step-by-step explanation:
1 Divided by 2 is .5 or 1/2
Answer:
f(-2) = 13
g(4) = -9
Explanation:
Whenever a question is asking you to find something like, in this example, f(-2) or g(4), you have to substitute whatever number is in the parentheses for every x in the function with that letter.
Let's try to find f(-2). We have to substitute -2 for every x in the function f and simplify:
Therefore, 
.
Next, let's try to find g(4). We have to substitute 4 for every x in the function g and simplify:
Therefore, 
Answer:
3/2
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 5-2)/(8-2)
= 3/2
