Does the mapping diagram represent a function? Why or why not? х
y
-7

O A. No; the output value y=-4 pairs with two different input values.
B. No; each input pairs with only one output.
C. Yes; each input pairs with only one output.
D. No, the input values x = -7 and
x= -1 are paired with the same output value.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

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°
