The table below shows two equations:
2 answers:
(1) has solutions x = 3, x= - 1.5 and (2) has no solution
solving each equation
(1)
add 5 to both sides
|4x - 3 | = 9 ( remove bars from absolute value )
4x - 3 = 9 or 4x - 3 = - 9 ( by definition )
4x = 9 + 3 = 12 or 4x = - 9 + 3 = - 6
x = 3 or x = - 1.5
(2)
subtract 8 from both sides
|2x + 3 | = - 5
the absolute value cannot be equal to a negative quantity
thus |2x + 3 | = - 5 has no solution
Answer:
The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution.
Step-by-step explanation:
Rearranging the two equations, you get ...
- |4x -3| = 9 . . . . . has two solutions
- |2x +3| = -5 . . . . has no solutions (an absolute value cannot be negative)
The above-listed answer is the only one that matches these solution counts.
_____
Testing the above values of x reveals they are, indeed, solutions to Equation 1.

Answer:
A' is (1,2)
B' is (4,-3)
C 'is (2,-6)
Step-by-step explanation:
A is (-1,2)
B is (-4,-3)
C is (-2,-6)
so the images of the points are reflected across the y axis, so the x coordinate is the opposite:
A' is (1,2)
B' is (4,-3)
C' is (2,-6)
Answer:
83.2%
Step-by-step explanation:
Just add all the percentages together and divide it by the number of scores, which in this case is 5.
A Because whenever you’re adding integers that have the same thing you keep the same signs in at the absolute value of each number
Solving for x?
If so X = -4
Answer:
the square root of -4 is irrational because you cant take the square root of a negative number.
