I need help with this pls, 15 pts

Answer:

I guess it's -2

Step-by-step explanation:

6-8x = 5x - 10x + 12

∴ 10x - 8x - 5x = 12 - 6

∴ 10x- 13x = 6

∴ - 3x = 6

∴ x = -6\3

∴ x = -2

Answer:

-2

Step-by-step explanation:

6-8x=5x-10x+12

5x-10x=-5x

=6-8x=-5x+12         MOVE -5x TO THE LEFT SIDE AND 6 TO THE RIGHT SIDE

= -8x+5x=12-6

= -3x=6

= -x=2

= x=-2

Answer:

y=29

Step-by-step explanation:

Answer:

y=29

Step-by-step explanation:

We move all terms to the left:

58/y-(2)=0

The domain of the equation: y!=0

y∈R

We multiply all the terms by the denominator

-2*y+58=0

We add all the numbers together, and all the variables

-2y+58=0

We move all terms containing y to the left, all other terms to the right

-2y=-58

y=-58/-2

y=29

Answer:

1/4

Answer: 0.39 ; 0.993

Step-by-step explanation:

Given that:

Mean of exponential distribution = 6

Using poisson :

P(X =x)Probability of failure in next 3 years :

Number of occurrences λ = 1 / 6 = 0.1667

P(X < 3) = 1 - e^-λx

P(X < 3) = 1 - e^-0.1667*3

P(X < 3) = (1 - e^-0.5)

P(X < 3) = 1 - 0.60653

P(X < 3) = 0.39346

= 0.393

B.)

Number of pc owned = 10 ; n = 10

P(atleast 1 fails) :

P(X ≥ 3)^n = 1 - [1 - P(X < 3)] ^n

P(X ≥ 3)^n = 1 - (1 - 0.393)^10

P(X ≥ 3)^n = 1 - 0.607^10

= 1 - 0.00679

= 0.993

This question is based on the probability. Therefore, the probability that the CPU fails in the next three years is 0.393  and  the probability that at least one fails within the next three years is 0.993.

Given:

The CPU of a personal computer has a lifetime that is exponentially distributed with a mean lifetime of six years. You have owned this CPU for three years.

(a) We need to determined the probability that the CPU fails in the next three year.

It is given that, mean of exponential distribution = 6

By using Poisson distribution:

P(X =x) Probability of failure in next 3 years :

[tex]Number\, of \,occurrences\, \lambda = \dfrac{1}{6} = 0.1667[/tex]

[tex]P(X < 3) = 1 - e^{-\lambda x}\\P(X < 3) = 1 - e^{-0.1667\times 3}\\P(X < 3) = (1 - e^{-0.5})\\P(X < 3) = 1 - 0.60653\\P(X < 3) = 0.39346= 0.393[/tex]

(b) We need to determined the probability that at least one fails within the next three years.

Number of pc owned = 10 ; n = 10

P(at least 1 fails) :

[tex]P(X \geq 3)^n = 1 - [1 - P(X < 3)] ^n\\P(X \geq 3)^n = 1 - (1 - 0.393)^{10}\\P(X \geq 3)^n = (1 - 0.607)^{10} = = 1 - 0.00679 = 0.993[/tex]

Therefore, the probability that the CPU fails in the next three years is 0.393  and  the probability that at least one fails within the next three years is 0.993.

Answer:

4x-1>9

Step-by-step explanation:

4x>9+1

4x>10

x>2.5

Answer:

Please check the explanation.

Step-by-step explanation:

Given the table 1

x              y

-12           2

-10           10

0              -2

5              -6

8               -11

15              -15

From the table, it is clear that for each input there exists a unique output.

i.e.

According to the given table,

y = 2 at x=-12

y = 10 at x=-1 0

y = -1 at x=0

y = -11 at x=8

y = -15 at x=15

From the table, it is clear that for each input x, it has a unique output y.

Hence, table 1 is a function.

Given the table 2

x              y

9            -18

-20           0

-6              1

-17              16

9                17

11              19

This table does not produce a function, because the input x=9 produces two outputs.

i.e.

at x = 9, the y = -18

at x = 9, the y = 17

Therefore, the table 2 does not represent a function.

Perimeter = 30

Step-by-step explanation:

hypotenuse = [tex]\sqrt{5^2+12^2}[/tex]

hypotenuse = [tex]\sqrt{25+144}[/tex]

hypotenuse = [tex]\sqrt{169}[/tex]

hypotenuse = 13

Perimeter = 5+12+13

Answer:

X=4

Step-by-step explanation:

2x4=8 or 8/2

Answer:

x=8

y=4

Step-by-step explanation:

Answer:

Your point would be: (0,2)

x = 0

y = 2

Step-by-step explanation:

This would be the case if you're looking for the point by solving with substitution, or any other methods, of the systems of equations.

In any case, you are looking to find either x or y first.

I will demonstrate with the 'y' value, since it is easier when cancelling out the 'x' value.

2x - y = -2

2x + 4y = 8

(I want to make one of the two equations negative, so that I can eliminate or cancel out the 'x' value(s)).

- (2x - y = -2) --> -2x + y = 2

                          2x +4y = 8

---------------------------------------

                                5y = 10

                                ---     ---

                                 5      5

                              ------------

                                 y = 2

(Reason for putting a negative in front of the equation '2x - y = -2' was made in order to eliminate the value(s) '2x' in both equation, and in order to do that, one equation must be negative, while the other is positive, for example:

x + 2y = 6

x + 3y = 5

(You can make any of these equations negative, but only one equation is needed to be negative for the value you want to cancel out,

DO NOT TRY AND CANCEL OUT BOTH X AND Y)

-(x + 2y = 6)

Turn into:

-x - 2y = -6

x + 3y = 5

---------------

y = -1

(Back to the Original Problem)

We now need to find the 'x' value(s):

4(2x - y = -2)

8x - 4y = -8

2x + 4y = 8

----------------

10x = 0

---     ---

10     10

----------------

x = 0

Your final answer will be:

(0,2)

Answer:

From the figure, it can be seen that ΔJ'K'L' is formed from ΔJKL by the rotation of ΔJKL by 90 degrees counter-clockwise.

It can also be seen that ΔJ"K"L" is obtained from ΔJ'K'L' by the refrection of ΔJ'K'L' across the x-axis.

Therefore, the rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is given by
