Answer: y=-2x-9
Step-by-step explanation:
If ANGL is a square, then NG and LG are adjacent sides.
Adjacent sides are perpendicular. [Each angle is 90°]
The equation of line NG is 
.
By comparing it to equation in slope intercept form y=mx+c ( where , m= slope , c=y-interecpt)
slope =
Let slope of LG be <em>n</em>, then
[Product of slopes of two perpendicular line =-1]
Equation of a line passes through (a,b) and have slope m is given by :-
Equation of LG :
[In intercept form]
Answer:
A, a= 87
Step-by-step explanation:
a+36=123
Step 1: Subtract 36 from both sides.
a+36−36=123−36
a=87

180 degrees in a straight line
Answer:
the answer is 6
Step-by-step explanation:
In mathematics, an arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. so -20 + 14 is -8 so you just have to add 14 again to -8 to get 6

A) 0.8
B) 0.24
C) 0.56
D) 0.44
For A, since 1 in 5 is dry, 4 in 5 are not; 4/5 = 0.8
For B, we know that 30%, 0.3, of the ones that are not dry are contaminated:
0.3(0.8) = 0.24
For C, 100%-30%=70% of wells that are not dry are not contaminated; 0.7(0.8) = 0.56
For D, she will either have contaminated water or no water:
0.24+0.2 = 0.44
