Answer:
4
Step-by-step explanation:
slope,m=0 and y-intercept (0,4) means this is a horizontal line that crosses the y-axis at 4. so, y=mx+b becomes y=b or y=4 which is the equation of given line.
Given:
is the angle bisector of
.

To find:
The measure of
.
Solution:
It is given that
is the angle bisector of
. It means
...(i)
Now,

[Using (i)]

Divide both sides by 2.


Therefore, the required value is
.

Answer: 
Step-by-step explanation:
1. To write the number given in the problem (4,498,000,000) in scientific notation you must write it in the following form:

2. The decimal point must be written after the first digit and the exponent b must be positive and indicates the number of times the decimal point is move to the right. Therefore, you have:

Hello
the line passes by A ( 0 ; -2) and B (5 ; 0) equation : y = ax+b
a is a slop : a = (yb - ya)/(xb -xa)
a = (0+2)/(5-0)
a =2/5
y = (2/5)x+b
if x=5 and y= 0
0 = (2/5)(5)+b
b= - 2
the equation is : y = (2/5)x-2
