3x +8y+13x need help ASAP​

Answer:

6

Step-by-step explanation:

You first have to choose from Wide and Narrow.

Let's call them W and N

Then you have to choose 3 different pen colors.

Let call them, 1, 2, 3

So There are two choices from W and N.

Then we pick the number: 1, 2, 3.

so If you pick W, you will have 3 choices. Same for N.

So in total: 6 choices.

W= 3 choices, W1, W2, W3

N= 3 choices, N1, N2, N3

so 6 in total.

Answer:

d) firing will decrease for CS and increase for US

Step-by-step explanation:

The is the answer going by the probabilistic nature of the schedule. That is, as the probability of relieving reward increase has a direct effect on the CS leading to its decrease as well as a proportional increase for US. On the other hand, a decrease of probability of receiving reward will have an opposite effects on the schedule.

Answer:

B. 89

Step-by-step explanation:

LOE + EOV = LOV,

becomes

[tex]7x+12+4x+9=142\\11x+21=142\\11x=121\\x = 11[/tex]

LOE = 7x + 12, so:

[tex]7 * 11 + 12\\77 + 12\\89[/tex]

========================================

Work Shown:

(f + g)(x) = f(x) + g(x)

(f + g)(x) = x^2+x+1 + g(x) ............... plug in f(x) = x^2+x+1

(f + g)(x) = x^2+x+1 + x^2-9 ........... plug in g(x) = x^2-9

(f + g)(x) = (x^2+x^2)+x+(1-9)

(f + g)(x) = 2x^2+x-8

Step-by-step explanation:

The solution is 14.86

The length of the third side of the right angle triangle is 14.86

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Given data ,

Let the triangle be ΔABC

Now , the triangle ABC is a right angle triangle

And the value of the base of the triangle BC = 10

The value of the height of the triangle AB = 11

Now , the hypotenuse of the triangle AC is calculated from Pythagoras Theorem

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Substituting the values in the equation , we get

AC² = AB² + BC²

AC² = 11² + 10²

AC² = 121 + 100

AC² = 221

Taking square roots on both sides of the equation , we get

AC = 14.86

Therefore , the value of AC is 14.86

Hence , The length of the hypotenuse of the right angle triangle is 14.86

Answer:

L=18.1, W=11.0

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

✔️Area of the square = s²

Where,

s = (2x - 4)

Area = (2x - 4)² = (2x - 4)(2x - 4) = 2x(2x - 4) -4(2x - 4)

= 4x² - 8x - 8x + 16

Area of square = 4x² - 16x + 16

Area of rectangle = L × W = (3x - 6) × x

= 3x² - 6x

✔️Since both have the same area, therefore,

4x² - 16x + 16 = 3x² - 6x

Collect like terms

4x² - 3x² - 16x + 6x + 16 = 0

x² - 10x + 16 = 0

Factorize

x² - 2x - 8x + 16 = 0

x(x - 2) -8(x - 2) = 0

(x - 2)(x - 8) = 0

(x - 2) = 0 or (x - 8) = 0

x = 2 or x = 8

If we plug in x = 2 into any of the given side length, we would have 0. (i.e. 2x - 4 = 2*2 - 4 = 0)

So the value of x cannot be 2 because the length of any of the shape cannot be 0.

So therefore, the value of x = 8

Answer:

20x = -58 - 2y( Ans~ x= -29/11)

17x = -49 - 2y (Ans~ x = -49/19)

Step-by-step explanation:

(1) 20x = -58 2x

   20x + 2x = -58

   22x = -58

   x = -29/11

(2) 17x = -49 - 2x

   17x + 2x = -49

   19x = -49

   x = -49/19

U WELCOME!!

Answer:

y=1

x=-3

Step-by-step explanation:

20x=-58-2y

20x/20=(-58-2y)/20

x=(-58-2y)/20

17x=-49-2y

17x/17=(-49-2y)/17

x=(-49-2y)/17

(-58-2y)/20=(-49-2y)/17

17(-58-2y)=20(-49-2y)

-986-34y=-980-40y

add 40y to both sides

6y-986=-980

add 986 to both sides

6y=6

divide both sides by 6

y=1

substitute

20x=-58-2(1)

20x=-60

x=-3

Proof: (substituting x & y values in original equations)

20(-3)=-58-2(1)

-60=-60

17(-3)=-49-2(1)

-51=-51

(b-7)m=r

Use the distributive property to multiply b-7 by m.

bm-7m=r

Add 7m to both sides.

bm=r+7m

The equation is in standard form.

mb=7m+r

Divide both sides by m.

mb/m = 7m+r/m

Dividing by m undoes the multiplication by m.

b= 7m+r/m

Divide r+7m by m.

b= r/m+7

Answer:

  (x, y) = (0, -6)

Step-by-step explanation:

Substitute for y in the second equation:

  2x -4(8x -6) = 24

  2x -32x +24 = 24

  -30x = 0

  x = 0

  y = 8·0 -6 = -6

The solution is (x, y) = (0, -6).
