Answer:
(x + 1 s 1) n (x + 12 1)
(x +1<1) n (x + 1 > 1)
Step-by-step explanation:
Just simplify each the statements.
Then compare and and see if the statements are contradictory and therefore FALSE, if so, then there is no solution.
(x + 1<-1) n (x + 1< 1)
(x <-2) n (x < 0) which is true, so there is a solution.
(x + 1 s 1) n (x + 12 1)
this doesn't make sense so there is no solution.
(x +1<1) n (x + 1 > 1)
(x < 0) n (x > 0)
This is not possible, the statements are contradictory and therefore FALSE, so there is no solution.
Answer:
a)
Slope form y=2x+3
Standard form 2x-y=-3
b)
Slope y=3/5x-6
Standard 3x-5y=30
c)
slope y=-3/2x+9
standard 3x+2y=18
d)
slope y=-3x+0
standard = 3x+y=0
Step-by-step explanation:
a)
Slope form y=2x+3
Standard form 2x-y=-3
b)
Slope y=3/5x-6
Standard 3x-5y=30
c)
slope y=-3/2x+9
standard 3x+2y=18
d)
slope y=-3x+0
standard = 3x+y=0
Answer:
3.875 lb
Step-by-step explanation:
Weight of table = 19lb 4 oz = 19-4/16 lb = 19.25 lb
Weight of each chair = 11 lb 9 oz = 11-9/16 lb = 11.5625 lb
Weight of 2 chairs = 2 x 11.5625 = 23.125 lb
Difference in weight between 2 chairs and one table
= 23.125 - 19.25
= 3.875 lb
Answer:
15 students are girls
Step-by-step explanation:
7+5=12
36÷12=3
3x5=15
c = 
using Pythagoras' identity on the right triangle
c = √( 4² + (
)² ) = √16 + 
=
