Step-by-step explanation:

Answer:

x = 22-3y/5-y

y=-22-5x/x-3

Step-by-step explanation:

Solve for x:

1)  Subtract 3y from both sides.

5x - xy = 22 - 3y

2) Factor out the common term x.

x(5 - y) = 22 - 3y

3) Divide both sides by 5 - y.

x = 22-3y/5-y

Solve for y:

1) Subtract 5x from both sides.

=xy + 3y = 22 - 5x

2) Factor out the common term y.

- y=(x-3)=22-5x

3) Divide both sides by x-3.

-y=22-5x/x-3

4) Multiply both sides by -1.

y=-22-5x/x-3

Answer:  z = 107; x = 5

Step-by-step explanation:

z = 107   They are vertically opposite angles, which they are equal.

z + (6x + 43) = 180

1. Plug in 107 for z.

107 + (6x + 43) = 180

2. Get rid of parentheses.

107 + 6x + 43 = 180

3. Sum up the number in the left sides.

      6x + 150 = 180

4. Subtract 150 from both sides.

                6x = 30

5. Divided 6 from both sides.

                  x = 5

Both solutions are valid, so the solutions to the quadratic function [tex]f(x) = 4x^2 - 9[/tex] are x = -3/2 and x = 3/2.

To solve the quadratic function [tex]f(x) = 4x^2 - 9[/tex] by factoring, we set the expression equal to zero and then try to factor it.

Step 1: Set f(x) equal to zero:

[tex]4x^2 - 9 = 0[/tex]

Step 2: Factor the quadratic expression:

The expression [tex]4x^2 - 9[/tex] is in the form of a difference of squares, which can be factored as follows:

[tex]a^2 - b^2 = (a + b)(a - b)[/tex]

In our case, a = 2x and b = 3:

[tex]4x^2 - 9 = (2x + 3)(2x - 3)[/tex]

Step 3: Set each factor equal to zero and solve for x:

First factor: 2x + 3 = 0

Subtract 3 from both sides:

2x = -3

Divide both sides by 2:

x = -3/2

Second factor: 2x - 3 = 0

Add 3 to both sides:

2x = 3

Divide both sides by 2:

x = 3/2

Step 4: Check the solutions:

Plug the values of x back into the original equation to verify:

For x = -3/2:

[tex]f(-3/2) = 4(-3/2)^2 - 9\\f(-3/2) = 4(9/4) - 9\\f(-3/2) = 9 - 9\\f(-3/2) = 0\\For x = 3/2:\\f(3/2) = 4(3/2)^2 - 9\\f(3/2) = 4(9/4) - 9\\f(3/2) = 9 - 9\\f(3/2) = 0[/tex]

Both solutions are valid, so the solutions to the quadratic function f(x) = [tex]4x^2 - 9[/tex] are x = -3/2 and x = 3/2.

Answer:

B) (x + 3)^2 = 17

Step-by-step explanation:

To complete the square you need to put x + or - half of the x coefficient.

So here it would be (x + 3)^2. However, we're trying to find x^2 + 6x - 8 = 0, not x^2 + 6x + 9 =  0, which is what (x + 3)^2 expands to. So we need to -9 from x^2 + 6x + 9 = 0 and add -8 from the original equation.

This simplifies to (x + 3)^2 - 9 - 8 = 0    --> (x + 3)^2 - 17 = 0

Then all you need to do is rearrange to give: (x + 3)^2 = 17

Step-by-step explanation:

The equation of P(E1 ∪ E2) that represents the condition that the mutually exclusive events is one of the events occurs, or both occur which is correct option(A).

Mutually Exclusive events is defined as in probability the particular addition rule is applicable when two occurrences are incompatible with one another. It claims that the probability of either event is equal to the probability of each event separately.

If E₁ and E₂ are said to be mutually exclusive events then the probability of an event E₁ occurring or the probability of event E₂ occurring is given as P(E₁) + P(E₂) :

P(E₁ ∪ E₂) = P(E₁) + P(E₂)

Hence, the equation of P(E1 ∪ E2) that represents the condition that the mutually exclusive events is one of the events occurs, or both occur.

Answer:

24 Ohms

Step-by-step explanation:

Resistance is a function of amperes. For each amp, there is one and only one value for resistance.

It works the other way, too.

E=IR (well-known relationship). If IR=12, R=12/I

R=E* (1/I)

When the current is 0.5 amp, R=12/0.5 - 24 ohms

Answer:

Step-by-step explanation:

h(t) = 32 = -16t^2 + 50t + 5

-16t^2 + 50t - 27 = 0

Drawing a graph gives time = 0.7 seconds.

The ball is 32 feet above the ground after 2.9 seconds

We have,

To determine the time at which the ball is 32 feet above the ground, we can set the height function h(t) equal to 32 and solve for t:

h(t) = 32

-16t² + 50t + 5 = 32

-16t² + 50t + 5 - 32 = 0

-16t² + 50t - 27 = 0

We can solve this quadratic equation using various methods, such as factoring, completing the square, or the quadratic formula.

Let's use the quadratic formula:

t = (-b ± √(² - 4ac)) / (2a)

Plugging in the values a = -16, b = 50, and c = -27, we have:

t = (-50 ± √(50² - 4(-16)(-27))) / (2(-16))

Simplifying further:

t = (-50 ± √(2500 - 1728)) / (-32)

t = (-50 ± √(772)) / (-32)

Now, we can calculate the two possible solutions:

t ≈ (-50 + √772) / (-32) ≈ 2.85 seconds (rounded to the nearest tenth)

t ≈ (-50 - √772) / (-32) ≈ 0.18 seconds (rounded to the nearest tenth)

Based on the graph of the function, the ball is 32 feet above the ground after approximately 2.9 seconds (rounded to the nearest tenth).

Thus,

The ball is 32 feet above the ground after 2.9 seconds
