Answer: $x=21$

Step-by-step explanation:

For this exercise it is important to remember that, by definition, the sum of the Exterior angles of a polygon is 360 degrees.

Knowing this, you can write the following equation:

$(4x-1)+3x+(5x+4)+105=360$

Now, you must solve for "x" in order to find its value. The steps are:

- Add the like terms:

$12x+108=360$

- Subtract 108 from both sides of the equation:

$12x+108-108=360-108\\\\12x=252$

- Divide both sides by 12:

$\frac{12x}{12}=\frac{252}{12}\\\\x=21$

Answer:
This is a linear function because there is a common difference of 4
⇒ 2nd answer
Step-by-step explanation:
- In the linear function there is a common difference between each two
consecutive data
- In the exponential function there is a common ratio between each two
consecutive data
- Lats check the data in the data in the table
(x) === 1 ⇒ 2 ⇒ 3
f(x) === 4 ⇒ 8 ⇒ 12
∵ x has consecutive numbers 1 , 2 , 3
∵ 8 - 4 = 4
∵ 12 - 8 = 4
∴ f(x) has a common difference 4
∵ 8 ÷ 4 = 2
∵ 12 ÷ 8 = 1.5
∴ f(x) has no common ratio
∴ The table represents a linear function with common difference 4
This is a linear function because there is a common difference of 4

What is the rate of change of the function?

scoundrel [369]

Answer:

rate of change = 3

Step-by-step explanation:

to find the rate of change $\frac{y1 - y2}{x1 - x2}$

(0,-4) (1,-1)

$\frac{-4+1}{0-1}$ = $\frac{-3}{-1}$ = 3

What is the slope of (4,1) and (6,-1)

schepotkina [342]

Answer:

slope = -1

Step-by-step explanation:

you <u>subtract the y-values</u> (-1-1=-2) then <u>subtract the x-values</u> (6-4=2) then divide the sum of the y-values by the sum of the x-values

$\frac{-2}{2}$ which simplifies to a slope of -1

Use the equation Y= 11 - 5X to find y when x=7.

kap26 [50]

Plug in x = 7. Then use the order of operations (PEMDAS) to simplify
y = 11 - 5*x
y = 11 - 5*7 .... x has been replaced with 7 (since x = 7 is given)
y = 11 - 35
y = -24
