Answer:
top down: ∞, 0, 1, 0, ∞
Step-by-step explanation:
The equation will have infinite solutions when the left side and right side simplify to the same expression. This is the case for the first and last expressions listed.
2(x -5) = 2(x -5) . . . . expressions are already identical
x +2(x -5) = 3(x -2) -4 ⇒ 3x -10 = 3x -10 . . . the same simplified expression
__
The equation will have no solutions when the x-coefficients are the same, but there are different added constants.
5(x +4) = 5(x -6) ⇒ x +4 = x -6 . . . not true for any x
4(x -2) = 4(x +2) ⇒ x -2 = x +2 . . . not true for any x
__
The equation will have one solution when coefficients of x are different.
5(x +4) = 3(x -6) ⇒ 2x = -38 ⇒ x = -19
First you have to have the absolute value isolated so the 2 has to be divided. Then set up the two cases and solve.
18a is correct, 18b is incorrect, 18c is correct, 18d is false, 18e is false, 18f is true, 19 is incorrect.
4. x < 5; 9*5 = 45; The answer has to be less than 45; 45/9 =5; so x has to be less than 5.
5. n <= -3; -14*-3 = -42; The answert has to be greater than or equal to 42; 42/-14 = -3; so n has to be less than -3 or equal to -3.
6. x > 24; The answer has to be less than -6; 24/-4 = -6; so the answer has to be greater than 24.
Hope this helped☺☺
The total cost of everything is $18.08
$20 minus $18.08
The answer is $2.02
