     x - y = 12 ⇒ 3x -  3y = 36
2x + 3y = 76 ⇒ 2x + 3y = 76
                                 5x = 112
                                  5       5
                                   x = 22.4
                              x - y = 12
                         22.4 - y = 12
                       - 22.4       - 22.4

3 baguettes and 2 rolls=£3
NISA [10]

Answer:

baguettes are b = $0.80  

rolls are r =  $0.30

Step-by-step explanation:

1b + 4r = 2

3b + 2r = 3       step 1 when we need to balance and make one the same

6b + 4r = 6       step 2  when both equations must have 1 same value ie) 4r we take 2r and x2 to all values on that same equation.

6b + 4r = 6  

-

1b + 4r = 2         step 3 when both equations show add we subtract them

5b = 4

b = 4/5

b = 0.8          b = 0.8 =   4/5   step 4 when we find x we plug in for x in this case we found b and plug in for b

1(0.8) + 4r = 2

0.8 + 4r = 2

4r = 2 - 0.8

4r = 1.2

r   = 1.2 /4

r   =  0.3

A system has two components: A and B. The operating times until failure of the two components are independent and exponentially
LuckyWell [14K]

Answer:

E(x) = \frac{1}{2} -- Component A

E(x) = \frac{1}{3} -- Component B

Step-by-step explanation:

Given

Distribution = Exponential

\lambda = 2 --- Component A

\lambda = 3 --- Component B

Solving (a): The mean time of A

The mean of an exponential distribution is:

E(x) = \frac{1}{\lambda}

We have:

\lambda = 2 --- Component A

E(x) = \frac{1}{2}

Solving (b): The mean time of B

The mean of an exponential distribution is:

E(x) = \frac{1}{\lambda}

We have:

\lambda = 3 --- Component B

E(x) = \frac{1}{3}

Need help please asp thank you so much
Aneli [31]

Answer:

x = -1, 3

Step-by-step explanation:

so what you need to do is graph each one because that's what the questions ask. One way for you to check your answer is to set the two equations equal to each other.

-x + 5 = x^2 - 3x + 2

you want to end up with one equation and having the equation equal 0. So add x to both sides to cancel out the x on the left side and then subtract 5 from both sides to cancel out the 5 on the left side.

0 = x^2 - 2x - 3

now you factor

0 = (x - 3) (x + 1)

x = -1, 3
