no
Step-by-step explanation:
condition to be a function is that for one x value, only one f(x) can be obtained
Answer:
Option C. d-17 = 22; d =39
Step-by-step explanation:
Let
d ----> the original number of drawings
we know that
The original number of drawings minus the number of drawings sold (17) must be equal to the remaining drawings (22)
so
The linear equation that represent this problem is
solve for d
adds 17 both sides
Equation 1:
| 2 x - 3 | + 5 = 4
| 2 x - 3 | = -1
There are no solutions.
Equation 2:
| 5 x + 3 | - 10 = 3
| 5 x + 3 | = 13
5 x + 3 = 13 and : 5 x + 3 = - 13
5 x = 10 5 x = - 16
x = 2 x = - 3.2
Answer:
B ) Equation 1 has no solution and equation 2 has solutions x = 2, - 3.2.
