Plug in 12 for y and rewrite the equation.
12 = 4x + 4
Subtract 4 from both sides.
8 = 4x
Divide by 4 on both sides.
2 = x
The ordered pair is (2, 12) and x = 2.
W=cost of one ticket
6w=$4
divide 6 on both sides
w=2/3 dollars per ticket
each child will get two tickets because 6/3 is 2
2/3×2= 4/3= $1.33 per child
Answer:
the equation | 5x + 10| = -7 has no solution for x ∈ R.
Step-by-step explanation:
Given the absolute value equation
| 5x + 10| = -7
- We know that absolute value is always positive.
Reason:
The reason is that the absolute value is the distance from the number 0. Hence, it can not be less than or equal to a negative number.
Conclusion:
Therefore, we conclude that the absolute value of any number would be either 0 or positive as it can not less than or equal to a negative number.
Therefore, the equation | 5x + 10| = -7 has NO SOLUTION for x ∈ R.
Answer:
-48
Step-by-step explanation:
20 x -2 = -40
-2/5 x 20 = -8
-40-8=-48
