Does the graph represent a function and if so, why? No, some of the ordered pairs in this list have the same second element. Yes, no two sets of ordered pairs occupy the same location. No, some of the ordered pair in this graph have the same first element. Yes, there is more than one ordered pair in this list.

No, some of the ordered pair in this graph have the same first element.

Step-by-step explanation:

The relation of a function is that it expresses a dependence of one element on another. There is a one to one relation, which means that one point can not be used more then once.

Some ordered pairs in this graph have the same first element and are used more then once. So this graph can not represent a function.

i just took the test, the correct answer is .. 31.5 in.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
