Answer:

1.-   m = 13

2.-   \(x<-\frac{2}{3}\)

3.-   y = 3

Step-by-step explanation:

In all cases we need to start with an equation or an inequality and slove for the variable:

Case 1.   : 2 m - 13 = m + 3

\(2m-13=m+3\\2m-m=3+13\\m=16\)

Case 2.   : 2 x + 1 > 8 x + 5 + 20

\(2x+1>8x+25\\1-25>8x-2x\\-24>6x\\-4 >x\\x<-4\)

Case 3.  :  9 - y = 2  y

\(9-y=2y\\9=2y+y\\9=3y\\y=3\)

The turning points of the function y = x³ - 3x² - 9x + 4 are (3, -23) and (-1, 9).

To determine the turning points of the given function y = x³ - 3x² - 9x + 4, we need to find the critical points where the derivative of the function is equal to zero.

1. Find the derivative of the function:

  y' = 3x² - 6x - 9

2. Set the derivative equal to zero and solve for x:

  3x² - 6x - 9 = 0

3. Factorize the quadratic equation:

  3(x² - 2x - 3) = 0

4. Solve the quadratic equation by factoring or using the quadratic formula:

  (x - 3)(x + 1) = 0

  This gives us two possible values for x: x = 3 and x = -1.

5. Substitute these critical points back into the original function to find the corresponding y-values:

  For x = 3:

  y = (3)³ - 3(3)² - 9(3) + 4

    = 27 - 27 - 27 + 4

    = -23

  For x = -1:

  y = (-1)³ - 3(-1)² - 9(-1) + 4

    = -1 - 3 + 9 + 4

    = 9

6. Therefore, the turning points are (3, -23) and (-1, 9).

Note: It appears that there was a typo in the original equation, where the term "-9x" should have been "-3x²". The above solution assumes the corrected equation.

For X ≤ 15, n = 20, π = .70 ; compound event probability is approximately 0.0008 .

For X > 8, n = 11, π = .65 ; compound event probability is  approximately 0.9198.

For X ≤ 1, n = 13, π = .40 ; compound event probability is  approximately 0.6646 .

a. To calculate the probability of the event X ≤ 15, n = 20, π = .70, we will use the binomial distribution formula:

P(X ≤ 15)

=  ∑_(k=0)¹⁵〖(20Ck)(0.70)^k (0.30)^(20-k) 〗

Using a binomial distribution calculator, we can find this probability to be approximately 0.0008 (rounded to 4 decimal places).

b. To calculate the probability of the event X > 8, n = 11, π = .65, we will first find the probability of X ≤ 8, and then subtract this value from 1 to find the complement probability:

P(X > 8) = 1 - P(X ≤ 8)

= 1 - ∑_(k=0)⁸〖(11Ck)(0.65)^k (0.35)^(11-k)〗

Using a binomial distribution calculator, we can find the probability of X ≤ 8 to be approximately 0.0802.

Therefore, the probability of X > 8 is approximately 0.9198 (rounded to 4 decimal places).

c. To calculate the probability of the event X ≤ 1, n = 13, π = .40, we will use the binomial distribution formula:

P(X ≤ 1)

= ∑_(k=0)¹〖(13Ck)(0.40)^k (0.60)^(13-k)〗

Using a binomial distribution calculator, we can find this probability to be approximately 0.6646 (rounded to 4 decimal places).

Answer:

Step-by-step explanation:

The solution to the system of equations is x = -3 and y = -4.

To solve the system of equations:

Equation 1: 2x - y = -10

Equation 2: 3x + 2y = -1

We can use the method of substitution or elimination to find the values of x and y.

Let's use the method of elimination:

Multiply Equation 1 by 2 to make the coefficients of y in both equations equal:

2(2x - y) = 2(-10)

4x - 2y = -20

Now, we can eliminate y by adding Equation 2 and the modified Equation 1:

(3x + 2y) + (4x - 2y) = -1 + (-20)

7x = -21

x = -3

Substitute the value of x into Equation 1 to solve for y:

2(-3) - y = -10

-6 - y = -10

y = -10 + 6

y = -4

Therefore, the solution to the system of equations is x = -3 and y = -4.

The speed of Jake's initial trip is x = 24 kilometers per hour, and the speed of the return trip is x + 6 = 30 kilometers per hour.

Let's assume that Jake's speed during the initial trip is represented by "x" kilometers per hour.

On the return trip, he drives 6 kilometers per hour faster, so his speed can be represented as "x + 6" kilometers per hour.

To find the time taken for each trip, we can use the formula Time = Distance / Speed.

For the initial trip, the time taken is 120 kilometers divided by x kilometers per hour, which gives us 120/x hours.

On the return trip, the time taken is 120 kilometers divided by (x + 6) kilometers per hour, which gives us 120/(x + 6) hours.

According to the problem, the return trip takes 1 hour less than the initial trip. So we can set up the equation:

120/x - 1 = 120/(x + 6)

To solve this equation, we can multiply both sides by x(x + 6) to eliminate the denominators:

120(x + 6) - x(x + 6) = 120x

Simplifying this equation:

120x + 720 - x² - 6x = 120x

Combining like terms:

x² + 6x - 720 = 0

Now we can solve this quadratic equation by factoring or using the quadratic formula. By factoring, we find:

(x + 30)(x - 24) = 0

This gives us two potential solutions: x = -30 or x = 24.

Since speed cannot be negative, we discard the solution x = -30.

Therefore, the speed of Jake's initial trip is x = 24 kilometers per hour, and the speed of the return trip is x + 6 = 30 kilometers per hour.

So, Jake drives at a speed of 24 kilometers per hour on the initial trip and 30 kilometers per hour on the return trip.

Step-by-step explanation:

✅124° + x° = 180° (linear pair/angles on a straight line)

Subtract 124° from each side

124° + x - 124° = 180° - 124°

x = 56°

✅x + y + 125° + 65° = 360° (sum of interior angles of a quadrilateral)

plug in the value of x

56 + y + 125 + 65 = 360

246 + y = 360
