Answer:
I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.
For example, if you have the following inequation:
x-2> 1
x>3
Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U (3, inf) instead of 'x>3 or x<-3' which can be confusing.
First, calculate 40% of 90
90 x (40/100 ) = 90 x 0.4 = 36
A. 72 NO
B. 36 YES
C. 4/5 x 9 = 36/5 NO
D. 40/100 / 90 = 1/225 NO
E. 2/5 x 90 = 36 YES
Answers:
B and E
Y intercept = -2
There is no X intercept as it is an asymptote
Answer:
y=-1/2 x-4
Step-by-step explanation:
y=mx+c
c is -4
m is rise/run so -1/2
