The solution point is (4,2).

Step-by-step explanation:

Equation of straight line passing through the points (0,0) and (4,2) is given by

⇒ 2y = x ............ (1)

And the other straight line is y = - x + 6 .............. (2)

Now, solving equations (1) and (2) we get, y = - 2y + 6

⇒ 3y = 6

⇒ y = 2

And from equation (1) we get, x = 2y = 4

Therefore, the solution point is (4,2). (Answer)

Just doing one! Here's my problem:    x-y-11  x-3y=1

So when you subsitute everything it should look like this: 1y-11-3y=1 (There needs to be a one in front of the y because it's just always been there. they don't always put it in the eqation.)  You need to + the 11 and you have to do that to each side. So... 1y-11-3=1
                                                                                                                +11    +11
Now it should look like this: 1y-3y=12
Combine the 1y and -3y to get -4y=12      Last step is divide -4y and 12 by 4  . Answer is y=3

The residents of a certain dormitory have collected the following data: People who live in the dorm can be classified as either
Vlad [161]

Answer:

33.33%

Step-by-step explanation:

Given :

Breakup percentage = 15

New relationship percentage = 30

To obtain the steady state percentage of residents who are uninvolved, we could relate the scenario to the natural unemployment rate relation : seperation rate ÷ (seperation rate * finding rate)

Hence, we could use the Relation as this ;

Breakup percentage ÷ (Breakup percentage + new relationship rate)

15% ÷ (15% + 30%)

0.15 ÷ (0.15 + 0.30)

0.15 ÷ 0.45

= 0.33333

= 33.33%

Find the surface area of the shape below. Round your answer to two decimal places.
marin [14]

The surface area of the given shape is 285.01 ft²

<h3>Surface area of a cone </h3>

From the question, we are to calculate the surface area of the given shape.

The given shape in the diagram is a cone.

The surface area of a cone is given by the formula,

S = \pi r(r+l)

Where S is the surface area

r is the radius

and l is the slant height

First, we will calculate the slant height of the cone

l^{2}=9^{2} +5.6^{2} (<em>Pythagorean theorem</em>)

l^{2}=81+31.36

l^{2}=112.36

l}=\sqrt{112.36}

l=10.6 \ ft

∴ The slant height is 10.6 ft

Now, for the surface area

S = \pi \times 5.6(5.6+10.6)
S = \pi \times 5.6(16.2)

S = 90.72\pi  \ ft^{2}

S = 285.0053 \ ft^{2}

S ≅ 285.01 ft²

Hence, the surface area of the given shape is 285.01 ft²

I’ll give u brainiest pls help me im so lost
Vlad1618 [11]

Answer:

(f o g)(4)=27

Step-by-step explanation:

(f o g)(4)=2x+5

f(g(4))=2x+5

f(4²-2(4)+3)=2x+5

f(16-8+3)=2x+5

f(8+3)=2x+5

f(11)=2x+5

f(11)=2(11)+5

f(11)=22+5

f(11)=27

Therefore, (f o g)(4)=27
