Suppose this relation forms a function: {(3,-5), (-2,9), (0,4), (x,7)}. What values are not possible for the value of x?

1 answer:

4 0

Since the definition of a function is that x values can’t repeat, any X values that are used in the other coordinates cannot be reused. So the answer has to be x cannot equal 3, -2, or 0

Answer:

ok so first you add all the prices together.

$9:00+$7:00+$8:00+$6:00+$4:00=34

then divide 34 by the number of prices.

34/5

then you get the mean

$6.8 is the mean

Answer:

See attachment for plot

Step-by-step explanation:

Given

$y =2x$

$R =+2$ --- increment in the rate

First, we need to model the new rate

A linear equation is:

$y = mx + b$

Where

$m = rate$

Compare $y =2x$ and $y = mx + b$ . we have:

$m =2$

The above represents the previous rate.

The new rate:

$R =+2$

Rewrite as:

$R = m+2$

$R = 2+2$

$R = 4$

So, the model is:

$y = Rx$

$y = 4x$

The plot at 1 and 2 minutes

When $x = 1$

$y = 4x = 4 * 1 = 4$

When $x = 2$

$y = 4x = 4 * 2 = 8$

So, we have:

$(x_1,y_1) =(1,4)$

$(x_2,y_2) =(2,8)$

Whether she moves backwards or forward, the distance covered remains the same

Since it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem. For the same reason, if m∠B < m∠C, then AC < AB. This is a contradiction to what is given. Therefore, it can be concluded that

Answer: Angle (B) is Congruent to Angle (C)
