This is a supplementary equation, so that means both of the equations added together would be 180 degrees. Therefore, you simply add them together to make them equal 180: 17x+14+4x-2=180.

therefore x=8.

you can check it by plugging 8 into both equations. 17(8)+14=150 and 4(8)-2=30

150+30 is 180

your answer is x=8

hope this helps!! :)

$\boxed{\large{\bold{\blue{ANSWER~:) }}}}$

Here,

The two lines l and m are parallel,

cut by a transversat line t

So The two angles are supplementary each other.

we know that, 

The sum of two supplementary angles are 180°

According to the question, 

(17x+14)°+(4x-2)°=180°

17x+14°+4x-2°=180°

17x+4x+14°-2°=180°

21x+12°=180°

21x=180°-12°

21x=168°

x=168°/21

x=8°

Therefore, 

The value of x is 8°

If y=36 when x=6 find x when y=42

emmasim [6.3K]

Answer:

x = 7

Step-by-step explanation:

First, solve by dividing y with x

When x = 6, y = 36

36/6= 6

6(x) = y is your equation.

Now plug in 42 for y

6(x) = 42

Isolate the x. Divide 6 from both sides

(6x)/6 = (42)/6

x = 42/6

x = 7

7 is your answer for x.

Determine which ordered pairs fall on the graph of f(x) = -2x-1

Pavlova-9 [17]

Answer:

No order Pair fall on the graph

Step-by-step explanation:

The given Function is

$f(x)= -2x -1$ ...............(i)

Now to see whether these ordered pairs Lay on it we will put each ordered pair in the equation (i)

Lets take first ordered pair (1,1)

here x = 1

putting it in (i) gives

$f(1)= -2(1) -1$

$f(1)= -3$

this is not equal to 1 so the order pair (1,1) does not fall on function $f(x)= -2x -1$

Lets take second ordered pair (-1,-4)

here x = -1

putting it in (i) gives

$f(-1)= -2(-1) -1$

$f(-1)= 1$

this is not equal to -4 so the order pair (-1,4) does not fall on function $f(x)= -2x -1$

Lets take third ordered pair (-2,-1/8)

here x = -2

putting it in (i) gives

$f(-2)= -2(-2) -1$

$f(-2)= 3$

this is not equal to -1/8 so the order pair (-2,1/8) does not fall on function $f(x)= -2x -1$

Lets take fourth ordered pair (0,-1/2)

here x = 0

putting it in (i) gives

$f(0)= -2(0) -1$

$f(0)= -1$

this is not equal to -1/2 so the order pair (0,-1/2) does not fall on function $f(x)= -2x -1$

3. A cone has a heighth and a base with radius r. You want to change the cone so its volume is tripled. What is the new height i

Sphinxa [80]

Answer:

Hence the new height is 3 times the original height .(h1=3h)

Step-by-step explanation:

Given:

A cone with has height and base with radius r .

To Find:

What is new height

Solution:

Consider as cone with height h base radius r, and volume v

Here given that only height changes for the cone i.e. r remains the unchanged or same or constant

The volume for a regular cone is given by ,

$V=pie*r^2*h/3$

Here V is directly proportional to h i.ee pie ,3 and r being constant

$V=K*h$

i.e V/h=constant

V1 and h1 are new dimensions for new cone

V/h=V1/h1

Here V1=3V

So V/h=3V/h1

1/h=3/h1

i.e h1=3h

Hence the height is 3 times the original height .
