Answer:

14 - 9x + 12 + x

This is an <em>expression </em>(not an equation), therefore it can't be solved.

<u>Factor the expression</u>

Collect like terms:

⇒ 14 + 12 - 9x + x

Combine like terms:

⇒ -8x + 26

Find the highest common factor of 26 and 8

Factors of 26: 1, 2, 13, 26
Factors of 8: 1, 2, 4, 8

Therefore, the highest common factor is 2

Factor out -2 from -8x + 26:

⇒ -2(4x + 13)

Alternatively, factor out 2 from 26 - 8x:

⇒ 2(13 - 4x)

Write an equation in slope intercept form given two points: (3,1),(0,10)

qaws [65]

Answer:

y = - 3x + 10

Step-by-step explanation:

We have to write an equation of a straight line in slope-intercept form that passes through the points (3,1) and (0,10).

Now, the equation of the straight line (using two points form) will be

$\frac{y - 1}{ 1 - 10} = \frac{x - 3}{3 - 0}$

⇒ y - 1 = - 3(x - 3)

⇒ y - 1 = 9 - 3x

⇒ y = - 3x + 10 (Answer)

{Since the slope-intercept form of a straight line equation is y = mx + c}

We know the equation of a straight line when any two points on the straight line ( $x_{1},y_{1}$ ), ( $x_{2},y_{2}$ ) are known, will be

$\frac{y - y_{1} }{y_{1} - y_{2}} = \frac{x - x_{1} }{x_{1} - x_{2}}$

Which table represents a linear function that has a slope of 5 and a y-intercept of 20? A 2-column table with 4 rows. Column 1 i

natali 33 [55]

Answer:

The 1st table represents a function

Step-by-step explanation:

* Lets explain how to solve the problem

- Function is a relation where each input has a single output

- The notation of the function is f(x) = y , where x is the input of the

function and y is the out put of the function

- The domain of the function is x and the range of the function is y

* Lets find which table represent a function

# First table:

x y

-3 -1

0 0

-2 -1

- In the first table

∵ -3 has only -1

∵ 0 has only 0

∵ -2 has only -1

∵ 8 has only 1

∵ Every x has a single y

∴ The table represents a function

∴ The 1st table represents a function

- In the second table

x y

-5 -5

0 0

-5 5

6 -6

∵ x = -5 has y = -5 and y = 5

∴ One x has two values of y

∴ The table doesn't represent a function

- In the third table

x y

-4 8

-2 2

-2 4

0 2

∵ x = -2 has y = 2 and y = 4

∴ One x has two values of y

∴ The table doesn't represent a function

- In the fourth table

x y

-4 2

3 5

-4 0

∵ x = -4 has y = 2 and y = 0

∴ One x has two values of y

∴ The table doesn't represent a function

Find the perimeter and area (in u)

sergey [27]

Perimeter= add all sides.
Since this is a rectangle, we can assume two sides equal 3 and two equal 4. Therefore, 3+3+4+4= 14

Area=sidexside
Therefore, 3x4=12
