This set of points is on the graph of a function.{(−3, 9), (−1, 1), (0, 0), (2, 4)}

Which points are on the graph of the inverse?

Select each correct answer.

Answers

Answer 1

Answer:

Answer: (9, -3), (1, -1), (0, 0), and (4, 2)

Step-by-step explanation:

Inverse is when the x's and y's are swapped:

The given points are: {(-3, 9), (-1, 1), (0, 0), (2, 4)}

The inverse points are: {(9, -3), (1, -1), (0, 0), (4, 2)}

Answer 2

Answer:

Answer:

(9, -3), (1, -1), (0, 0) and (4, 2)

Step-by-step explanation:

The definition of an inverse of a function is "the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function."

This means too find the inverse of a function using ordered pairs, switch the x- and y-coordinates.

This means that (-3, 9) goes to (9, -3); (-1, 1) goes to (1, -1); (0, 0) goes to (0, 0); and (2, 4) goes to (4, 2).

On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b = 2 when a = –2. Which equation represents this direct variation between a and b?

Answers

Answer:

The equation is b = -a

Step-by-step explanation:

Given,

The number b varies directly with the number a,

That is, we can write,

b ∝ a

⇒ b = ka

Where k is the constant of proportionality,

Given, if b = 2 then a = -2,

By substituting the value,

2 = k(-2)

⇒ k = -1

Hence, the equation that represents the direct variation between a and b is,

b = -a

y=kx is the equation for direct variation

The sun rises between two mountain peaks. The edge of one mountain peak (right) forms a tangent with the sun. The other does not. What is the measure of the arc of the sun that is showing given that y=113º. Note: you are solving for the arc measure, not the arc length. Round your answer to one decimal place, if necessary.

Answers

Answer:

226°

Step-by-step explanation:

According to the Tangent and Intersected Chord Theorem, if a tangent and a chord intersect at a point on a circle, then the measure of each angle formed is one-half the measure of its intercepted arc.

Therefore, if y = 113°, then y is one-half of the intercepted arc x.:

$y=(1)/(2)m\overset\frown{x}$

$2y=m\overset\frown{x}$

$2(113^(\circ))=m\overset\frown{x}$

$m\overset\frown{x}=226^(\circ)$

Therefore, the measure of arc x is 226°.

Which is bigger 8/10 or 79/100

Answers

To figure this out first we will convert each fraction in to a decimal. To do this we need to divide the numerator by the denominator.

8/10 = 8 ÷ 10 = 0.80

79/100 = 79 ÷ 100 = 0.79

So, 8/10 = 0.80 & 79/100 = 0.79.

Since 0.80 is more than 0.79 8/10 is bigger.

So 8/10 (0.80) is bigger than 79/100 (0.79).

Hope I helped ya!! :)

you can say 8/10 = 80/100 ⇒ 80/100 is bigger than 79/100 :)))
