What is the solution for the following system of equations? Use ANY method to solve. 2x + 8y = 4 x = -3y + 5 Question 4 options:
Elan Coil [88]

Answer:

x = 14, y= -3

Step-by-step explanation:

Solve the following system:

{2 x + 8 y = 4 | (equation 1)

{x = 5 - 3 y | (equation 2)

Express the system in standard form:

{2 x + 8 y = 4 | (equation 1)

{x + 3 y = 5 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + 8 y = 4 | (equation 1)

{0 x - y = 3 | (equation 2)

Divide equation 1 by 2:

{x + 4 y = 2 | (equation 1)

{0 x - y = 3 | (equation 2)

Multiply equation 2 by -1:

{x + 4 y = 2 | (equation 1)

{0 x+y = -3 | (equation 2)

Subtract 4 × (equation 2) from equation 1:

{x+0 y = 14 | (equation 1)

{0 x+y = -3 | (equation 2)

Collect results:

Answer:  x = 14, y = -3

Answer:

  • f(4) = -12
  • f(-2) = -6
  • f(2) = -10
  • f(0) = -8
  • f(-3) = -5

Step-by-step explanation:

Put the value where the variable is and do the arithmetic.

Personally, I find it easier not to deal with so many minus signs. I would rewrite the function to ...

  f(x) = -(8 +x)

I find it easier to evaluate the series of argument values when they are in increasing order. This serves as a check, because we expect the function values to be in decreasing order.

f({-3, -2, 0, 2, 4}) = -(8 +{-3, -2, 0, 2, 4}) = -{5, 6, 8, 10, 12} = {-5, -6, -8, -10, -12}

  • f(4) = -12
  • f(-2) = -6
  • f(2) = -10
  • f(0) = -8
  • f(-3) = -5

_____

As always, for repetitive evaluation of the same function, a spreadsheet or graphing calculator is a handy tool.

An engineering study indicates that 8.5% of the bridges in a large state are structurally deficient. The state's department of t
Wewaii [24]

Answer:

P(X=6)=(100C6)(0.085)^6 (1-0.085)^{100-6}=0.1063

Then the probability that exactly 6 bridges in the sample are structurally deficient is 0.1063 or 10.63%

Step-by-step explanation:

Let X the random variable of interest "number of bridges in the sample are structurally deficient", on this case we now that:

X \sim Binom(n=100, p=0.085)

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^{n-x}

Where (nCx) means combinatory and it's given by this formula:

nCx=\frac{n!}{(n-x)! x!}

And we want to find this probability:

P(X=6)

And if we use the probability mass function and we replace we got:

P(X=6)=(100C6)(0.085)^6 (1-0.085)^{100-6}=0.1063

Then the probability that exactly 6 bridges in the sample are structurally deficient is 0.1063 or 10.63%
