Answer: x = 5, 7

Step-by-step explanation:

       This equation is already factored for us, so we can split it into two separate equations set equal to 0 and solve for x.

Given:

(x - 7)(x - 5) = 0

Equation #1:

x - 7 = 0

x = 7

Equation #2:

x - 5 = 0

x = 5

Solution:

x = 5, 7

Answer:

x = 5, x = 7

Step-by-step explanation:

(x - 7)(x - 5) = 0 ← in standard factored form

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x - 5 = 0 ⇒ x = 5

What is Irrational Number?

An Irrational number is areal number that cannot be expressed as a ratio of integers; for example [tex]\sqrt{2}[/tex] is an irrational number. We cannot express any irrational number in the form of ratio, such as p/q, where p and q are integers, q[tex]\neq[/tex] 0. Again, the decimal expansion of an irrational number in neither terminating nor recurring.

Let us assume [tex]7\sqrt{56}[/tex] is rational.

So, we can write this number as

[tex]7\sqrt{56}[/tex] = a/b __(1)

Here, a and b are two co-prime numbers and b is not equal to zero.

Simplify the equation (1) divide by 7 both sides, we get

[tex]\sqrt{56}=\frac{a}{7b}[/tex]

Here, a and b are integers, so a/7b is a rational number, so [tex]\sqrt{56}[/tex] should be a rational number.

But [tex]\sqrt{56}[/tex] is a irrational number, so it is Contradictory.

Therefore, [tex]7\sqrt{56}[/tex] is irrational number.

Given events are independent events and the probability that getting an even number on die and getting odd number on a spinner numbered 1 to 5

In this question,

we have been given two events.

Let event A: rolling an even number on a die

event B: spin a spinner numbered 1 through 5 and get an odd number.

We can clearly observe that the occurrence of event A is not dependent on the other event B.

So, event A and event B are independent events.

The probability of event A is,

P(A) = n(A) / n(S)

here, sample space, n(S) = 6

n(A) = 3

So, P(A) = 3/6

P(A) = 1/2

The probability of event B is,

P(B) = n(B) / n(S)

here, sample space, n(S) = 5

n(B) = 3

So, P(B) = 3/5

Now we find the joint probability of these independent events.

⇒ P = P(A) × P(B)

⇒ P = 1/2 × 3/5

⇒ P = 3/10

===============================================

Reason:

In the first graph, it is possible to draw a single vertical line through more than one point on the blue graph. For instance, draw a vertical line through 1 on the x axis.

Because this happens, we consider the graph to "fail the vertical line test". This leads to the graph not being a function.

A function is only possible if any input in the domain leads to exactly one and only one output.

The input x = 1 leads to multiple outputs y = 3 and y = -3 simultaneously.

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

On the other hand, the second graph doesn't have this issue happening. It's impossible to draw a single vertical line through more than one point on the blue graph.

Therefore, this graph passes the vertical line test and it is a function. Whatever x input you pick, it leads to one y output only.

Step-by-step explanation:

First, we choose a variable to represent the unknown number.

1. Let x = the unknown number.

Then, we translate the sentence into an equation using the variable we chose.

"Twice the sum of six and a number is 38."

We do it piece by piece:

"the sum of six and a number":                        x + 6

"Twice the sum of six and a number":              2(x + 6)

"Twice the sum of six and a number is 38.":    2(x + 6) = 38

The common ratio of the geometric sequence 4, 10, 25, 62.5, . . . is 2.5. The answer is B.

A geometric sequence refers to a sequence of numbers, which the next term is obtained by multiplying the previous term with a constant, called a common ratio.

a(n) = a r^(n-1)

Where:

a(n) = nth term

a = first term

r = common ratio

The common ratio must be the same for all pairs of succeeding term to be called a geometric sequence.

To find the common ratio, use the formula

a(n) = a r^(n-1)

let n = 2, a = 4, a(2) = 10

10 = 4(r^(2 - 1)

10 = 4(r)

r = 2.5

Or just simply divide each succeeding pairs of the sequence.

r = 10/4 = 2.5

r = 25/10 = 2.5

Recursive Arithmetic Sequence Formula

The following is the recursive formula to determine the nth term in an arithmetic series:

an = an-1 + d for n ≥ 2

where

The common difference is d, and an is the nth term of an A.P.

given that

a₁ = -121

a (n) =a (n-1) +13 so, d = +13

For example, we need to extend the sequence term by term in order to find the first five terms:

a(1) = -121

a(2) = a(1) + d = -121 + 13 = -108

a(3) = a(2) + d = -108 + 13 = -95

a(4) = a(3) + d = -95 + 13 = -82

a(5) = a(4) + d = -82 + 13 = -69

a(6) = a(5) + d = -69 + 13 = -56

a(7) = a(6) + d = -56 + 13 = -43

Answer:

B.  -2  <  x  <  4

Step-by-step explanation:

The function is (x +2)/(x-4) and we are asked to determine the x interval when the inequality (x +2)/(x-4) < 0 is satisfied

1. Find the critical points

The critical points are

x = - 2 when the numerator becomes -2 + 2 = 0, and f(x) = 0

and

x = 4 when the denominator becomes 4 - 4 = 0 and (x + 2)/0 is undefined

So critical points are -2 and 4

2. Use these critical points to divide the number line into intervals
The intervals are -∞ < x < -2, -2 < x < 4 and 4 < x < ∞
these can be re-written as x < -2, -2 < x < -4 and x > 4

3. For each  of these intervals take a test point and see if it satisfies that inequality
(a) -∞ < x < -2    Take x = -3 which is less than -2
We get f(-3) =  (-3 + 2)/(-3 -4) = -1/-7 which is + 1/7 and does not satisfy the (x+2)/(x-4) < 0 inequality.

So we can discard this interval
(b) For interval -2 < x < 4, Let's take x = 0
(0+2)/(0-4) = 2/(-4) = -1/2 = -0.5 which does satisfy the inequality
(x+2)/(x-4) <0, so this is a valid interval

(c) For interval x > 4, take x = 5
(x+2)/(x-4 ) = (5 + 2)/(5-4) = 7/1 = 7 and does not satisfy (x+2)/(x-4 ) < 0

So the interval which satisfies the inequality is -2 < x < 4

Option D is the correct answer.

Triangle Inequality Theorem states that the sum of two side lengths of a triangle is always greater than the third side.

If this is true for all three combinations of three combinations of side lengths.

i.e., a + b > c , b + c > a and c + a > b then the length form a triangle.

(A) 10 + 11 = 21 > 20

And 11 + 20 =31 > 10

And, 20 + 10 = 30 > 11

So, it forms a triangle

(B) 14 + 16 = 30 >28

And 16 + 28 = 44 >14

And 28 + 14 = 42 > 16

So, it forms a triangle

(C) 35 + 45 = 80 > 75

And 45 + 75 = 120 > 35

And 75 + 35 = 110 > 45

So, it forms a triangle

(D) 41 + 55 = 96 < 98

It does not form a triangle

because sum of two sides lengths is less than the third side length.
