The answer is -5/1 or -5

Step-by-step explanation:

Answer:

p=32

Step-by-step explanation:

4+12=16

16×2=32

p=32

After substituting W = 12, h = 4, in the equation P = 2(w + h), P = 32

"An element greater than or equal to all the elements in a given set."

"It is an expression which contains an equal symbol."

For given question,

Given equation: P = 2(w + h)

W = 12, h = 4

After substituting these values in given equation,

⇒ P = 2 × (12 + 4)

⇒ P = 2 × 16

⇒ P = 32

[1]   x + 5y - 4z = -10

[2]   2x - y + 5z = -9

[3]   2x - 10y - 5z = 0

Eliminate x by adding -2[1] to [2], and adding -1[2] to [3]:

-2(x + 5y - 4z) + (2x - y + 5z) = -2(-10) + (-9)

-2x - 10y + 8z + 2x - y + 5z = 20 - 9

[4] -11y + 13z = 11

-(2x - y + 5z) + (2x - 10y - 5z) = -(-9) + 0

-2x + y - 5z + 2x - 10y - 5z = 9

[5]  -9y - 10z = 9

Eliminate y by adding -9[4] to 11[5]:

-9(-11y + 13z) + 11(-9y - 10z) = -9(11) + 11(9)

99y - 117z - 99y - 110z = -99 + 99

-227z = 0

z = 0

Plug this solution into either [4] or [5] and solve for y :

[5] -9y - 10(0) = 9

-9y = 9

y = -1

Plug them both into either of [1], [2], or [3] and solve for x :

[1] x + 5(-1) - 4(0) = -10

x - 5 = -10

x = -5

(2)

[1] 2x - y + z = -4

[2] z = 5

[3] -2x + 3y - z = -10

Substitute [2] into [1] and [3]:

2x - y + 5 = -4

[4] 2x - y = -9

-2x + 3y - 5 = -10

[5] -2x + 3y = -5

Solve [4] for y :

2x - y = -9

2x + 9 = y

Substitute this into [5] and solve for x :

-2x + 3(2x + 9) = -5

-2x + 6x + 27 = -5

4x = -32

x = -8

Plug this into either [4] or [5] to solve for y :

[4] 2(-8) - y = -9

-16 - y = -9

y = -5

Step-by-step explanation:

f(x)= 2x + 9

               Cost per car

Change 9 to 6.

f(x) = 2x + 6

Because 9 was the y-intercept and it was changed to 6, or 3 units down, the function would be be translated 3 units down

Answer:

The cost of the system is $163 and The cost of the games is $489

Step-by-step explanation:

∵ A video game system and several games are sold for $652

∵ The cost of the games is 3 times as much as the cost of the system

→ Assume that the cost of the system is $x

∵ The cost of the system = x

∴ The cost of the games = 3 × x = 3x

∵ The total cost of the system and the games = 652

→ Equate the sum of the cost of the system and the cost of the games

   by 652

∴ x + 3x = 652

→ Add the like terms in the left side

∴ 4x = 652

→ Divide both sides by 4 to find x

∵ [tex]\frac{4x}{4}=\frac{652}{4}[/tex]

∴ x = 163

∵ The cost of the system = x

∴ The cost of the system is $163

∵ The cost of the games = 3x

∴ The cost of the games = 3(163) = 489

∴ The cost of the games is $489

Step-by-step explanation:

The value of the variable x will be 2. Then the radius of the circle will be 5.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The radius of the circle is x + 3. And the area of the circle is 25π. Then the equation will be

25π = π(x + 3)²

(x + 3)² = 25

x + 3 = 5

x = 5 - 3

x = 2

Then the radius will be

r = x + 3 = 2 + 3 = 5

The value of the variable x will be 2. Then the radius of the circle will be 5.

Answer:

X^2-x- 8/x+4

Step-by-step explanation:

X+4 becomes a negative 4

Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.
