Answer:

Linear.

Cubic.

Step-by-step explanation:

Two functions always share the domain (-∞, ∞) and range (-∞, ∞) are linear and cubic.

" Domain is defined as the set of all input values in the given function."

" Range is defined as the set of all output values in the given function."

According to the question,

For linear function we can put all the real numbers for the independent variable 'x' that is ( -∞ , ∞).

Domain of a linear function = ( -∞ , ∞).

Output values of the linear function is set of all real numbers (-∞,∞).

Range of a linear function = (-∞,∞).

For cubic function

Cubic function is an odd polynomial . One end extends to +∞ and other end to -∞.

Domain and range of cubic function (-∞,∞).

Hence, two functions always share the domain (-∞, ∞) and range (-∞, ∞) are linear and cubic.

Answer:

6.7638 × 10^10

Step-by-step explanation:

Answer:

9,000

5,025

Step-by-step explanation:

Answer:

Simplifying

y + -1k = m(x + -1h)

Reorder the terms:

-1k + y = m(x + -1h)

Reorder the terms:

-1k + y = m(-1h + x)

-1k + y = (-1h * m + x * m)

-1k + y = (-1hm + mx)

Solving

-1k + y = -1hm + mx

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '-1y' to each side of the equation.

-1k + y + -1y = -1hm + mx + -1y

Combine like terms: y + -1y = 0

-1k + 0 = -1hm + mx + -1y

-1k = -1hm + mx + -1y

Divide each side by '-1'.

k = hm + -1mx + y

Simplifying

k = hm + -1mx + y

Step-by-step explanation:

Answer: 4(5y−2)=40

Divide both sides by 4.

5y−2=  

4

40

​

Divide 40 by 4 to get 10.

5y−2=10

Add 2 to both sides.

5y=10+2

Add 10 and 2 to get 12.

5y=12

Divide both sides by 5.

y= 12/5 or 2.4 please give brainliest

Answer:

Part A - Represents a function

Part B - Doesn't represent a function.

Step-by-step explanation:

A set is just a list of numbers to check. The question is asking you based on the set...

(-5, 8)

(-6, 2)

(-2, -6)

(-1, 8)

(4,6)

if it is a valid function.

At NO point should a function have multiple x values. This fails the Vertical Line Test if visualized on a graph.

For Part A, there are no duplicate x values, meaning this function is valid.

For Part B, there is a duplicate x value - (2,9) & (2,4). Because of this, immediately the function is invalid. There can not be any duplicate x values in a valid function, PERIOD. If graphed, it fails the vertical line test.

Answer:

x = 3

Step-by-step explanation:

(13x - 2) and (12x + 1) are vertically opposite angles and are congruent , so

13x - 2 = 12x + 1 ( subtract 12x from both sides )

x - 2 = 1 ( add 2 to both sides )

x = 3

Answer:

the last choice

Step-by-step explanation:

i mean, you judt gotta find the points of the letters.

you can first find the coordinates of point A, which is 3, 2

based off of that, the rest of the answer choices don't have A as 3, 2.

so, with Process of Elimination, its the last one.

Answer:

SF = 2/5

Step-by-step explanation:

The side on figure A which has the 10 is between angles with one mark and 2

The side on figure B which has the 4 is between angles with one mark and 2

The scale factor is what we multiply 10 by to get 4

10 * SF = 4

Divide each side by 10

10 * SF /10= 4/1-

SF = 4/10

SF = 2/5

Answer:

-17

Step-by-step explanation:

(I originally posted this as a comment because Brainly was not allowing me to answer).

-8 is a negative number, which means many operations don't work the same on it. Subtracting a positive number from a negative number will give you the same result as adding the two positive numbers (in this case, 8 + 9), though the answer will also be negative. Hope this helps!
