Step-by-step explanation:
let's think about it logically :
|x| can only be positive, from 0 to +infinity.
but the second part "- 4" will bring the result for small x values into the negative realm.
x = 0 gives us f(x) = -4.
x = 4 gives us f(x) = 0
x = -4 gives us f(x) = 0
so, if is the 3rd graph (bottom left).
Let x = Mrs. D's salary last year
13% = 13/100 = 0.13
6500 is 13 percent of Mrs. D's salary, so:
0.13(x) = 6500
0.13(x)/0.13 = 6500/0.13
x = 50,000
Mrs. D's salary last year was 50,000 dollars.
Answer:
x > 4/3
Step-by-step explanation:
The first inequality can be solved this way ...
3x -91 > -87
3x > 4 . . . . . . . add 91
x > 4/3 . . . . . . divide by 3
__
The second inequality has solution ...
21x -17 > 25
21x > 42 . . . . . . add 17
x > 2 . . . . . . . . . divide by 21
__
The solution set is the union of these overlapping solutions, so will be equal to the first solution:
x > 4/3
Answer:
1). 24
2). 8
Explanation:
1).
285$ - 45$ = 240$
240$/10 = 24$
Therefore, he pays 24$ a month.
2).
Let x be the number than triple:
3x - 5 = 19
3x = 19 + 5
3x = 24
x = 24/3
x = 8
