-4(x-6) ≤ - 2x+6
-4x-24≤ -2x+6
+2x +2x
-2x-24≤+6
+24 +24
-2x ≤ 30
Divide both sides by -2
and you get....
x ≥ -15
You switch the inequality sign because you're dividing by a negative.
I hope all is well, and you pass! Good luck, rockstar! (:
Answer:
1. x = -37 - 7y
2. x = 7+3y/4
Answer:
$160
Step-by-step explanation:
Simple interest=principal×time×rate/100
Principal=$800
Time=5years
Rate=4%
S.I=800×5×4/100
S.I=8×4×5
S.I=160
So the simple interest is $160
Answer:
large jar
Step-by-step explanation:
large jar= £1.54 (divide) 440= 0.0035
small jar= £1.26 (divide) 340= 0.0037
as the large jar cost less (0.0035 > 0.0037) the large jar is the best value for money
3y - ( 4y + 19 ) = - 13 ;
3y - 4y - 19 = - 13 ;
- y - 19 = - 13 ;
-y = 19 - 13 ;
-y = 6 ;
y = - 6 ;
Then, x = 4 * ( - 6 ) + 19 ;
x = - 24 + 19 ;
x = - 5 ;
The solution of the system is x = - 5 and y = - 6 ;
