No; a range value has two domain values.

No; a domain value has two range values.

The offenders here are the ordered pairs (-2, 1) and (-2, 2). With any function we only want to get out <em>one specific</em> output (in the range) for any one input (in the domain). If you fed this function a -2 as input, it wouldn't know whether to give you out a 1 or a 2! This property - one input in, one output out - is essential for a function, so the relation shown does <em>not </em>describe one.

True [87]

Answer:

Approximately 45% students signed up for neither canoeing or trekking.

Step-by-step explanation:

First we subtract the number of the students who signed up from the number of the total students to find the number of the students who did not signed up for either.

But there are 13 students who signed up canoeing and also for trekking.

Hence the number of students they signed up for activity is

72 + 23 - 13 = 82

And the number of students they not signed up for any activity is

150 - 82 = 68

so 68 students signed up neither for trekking nor canoeing. The percentage of those students are :

$\frac{68}{150}$ × 100 = 45.3333%

Approximately 45% students signed up for neither canoeing or trekking.

Oksanka [162]

Answer:

x=c/a-b/a

Step-by-step explanation:

ax+b=c

1) Subtract b from both sides:

ax=c-b

2) Divide both sides by a:

x=c/a-b/a
