Subtraction property of inequality

Step-by-step explanation:

Step 1: Definition of Subtraction property

Subtraction property of equality refers to balancing an equation by using the same mathematical operation (minus) on both sides.

Step 2: Relate the definition above with the given question.

It can be seen from the statements in the question that 3 was subtracted from both sides of the initial equation to get:

\(x + 3 = 17 \\ x + 3 - 3 = 17 - 3 \\ x = 14\)

If G is not a cyclic group, then it does not have a subgroup of order p. Conversely, if G is cyclic, then it has a unique subgroup of order p.

The statement "A group G whose order is a prime number has only two subgroups, G itself and 1 = {1}" means that if G is a group with a prime number of elements, then the only subgroups of G are the trivial subgroup {1} and the group G itself.

In other words, there are no other proper subgroups of G besides these two.

The statement "A group G whose order is (p-1) where p is a prime number has a subgroup of order p if and only if G is cyclic" means that if G is a group with (p-1) elements, where p is a prime number, then G has a subgroup of order p if and only if G is a cyclic group.

In other words, if G is not a cyclic group, then it does not have a subgroup of order p. Conversely, if G is cyclic, then it has a unique subgroup of order p.

Answer:

Step-by-step explanation:

You want the coordinates of the vertices of QRST after it has been translated right 2 units, then reflected across the y-axis. The original coordinates are Q(1, 5), R(3, -1), S(0, 0), T(-2, 3).

The problem statement is written as a composition of the transformations Ry and T(2,0). A composition of functions is generally executed right to left, meaning the translation will be done first, then the reflection.

The numbers in the translation vector are added to the coordinates:

  (x, y) ⇒ (x+2, y+0)

Reflection over the y-axis changes the sign of the x-coordinate:

  (x, y) ⇒ (-x, y)

Then the composition of transformations is ...

  (x, y) ⇒ (-(x+2), y)

  Q(1, 5) ⇒ Q'(-3, 5)

  R(3, -1) ⇒ R'(-5, -1)

  S(0, 0) ⇒ S'(-2, 0)

  T(-2, 3) ⇒ T'(0, 3)

The value of the expression f(a) is f(a) = a^2 + 7a, based on the given function f(x) = x^2 + 7x and the value x = a

The given parameters in the question are:

f(x) = x^2 + 7x and

x = a as in f(a)

This means that the equation of the function f(x) is given as:

f(x) = x^2 + 7x

To calculate the value of the function f(a), we simply substitute a for x in the equation of the function f(x) = x^2 + 7x.

This means that we set x to a in the equation of the function f(x) = x^2 + 7x.

So, we have;

f(a) = a^2 + 7a

The above equation cannot be further simplified or expanded

So, we conclude that

Based on the given function f(x) = x^2 + 7x and the value x = a, the value of the expression f(a) is f(a) = a^2 + 7a

Answer:

I think 2nd option is correct

Answer:

80°

Step-by-step explanation:

The sum of the interior angles in a hexagon is 720°. This means that:

y + (2y - 20) + (2y - 20) + y + (2y - 20) + (2y - 20) = 720° - we can simplify this

10y - 80 = 720° - now, add 80 to both sides

10y = 800 - finally, divide both sides by 10

y = 800 ÷ 8 = 80°

Answer:

The total number of students is 3,000.

Step-by-step explanation:

Given that of the total number of candidates in an examination, 40% fail in first subject, of the rest 10% fail in the second and of those that pass in these two subjects, only 75% pass in the remaining subject, knowing that the number of unsuccessful candidates exceeds that of that of successful by 570, to find the total number of students the following calculation must be performed:

40 + (60 x 0.1) = 46

54 x 0.75 = 40.5

40.5% pass the 3 exams, while the remaining 59.5% do not.

59.5 - 40.5 = 19

19% = 570

570/19 = 30

30 x 100 = 3000

Thus, the total number of students is 3,000.

Answer:

2009

Step-by-step explanation:

The question can be interpreted as:

\(f(x) = -1.330x^2 + 5.149x + 5.517\)

Required

Determine x when f(x) = 10.5

Substitute 10.5 for f(x) in \(f(x) = -1.330x^2 + 5.149x + 5.517\)

\(10.5 = -1.330x^2 + 5.149x + 5.517\)

Collect Like Terms

\(-1.330x^2 + 5.149x + 5.517-10.5=0\)

\(-1.330x^2 + 5.149x -4.983=0\)

Using quadratic formula

\(x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}\)

Where

\(a = -1.330\)

\(b = 5.149\)

\(c = -4.983\)

\(x = \frac{-5.149 \± \sqrt{5.149^2 - 4*-1.330*-4.983}}{2*-1.330}\)

\(x = \frac{-5.149 \± \sqrt{0.002641}}{-2.660}\)

\(x = \frac{-5.149 \± 0.0514}{-2.660}\)

Split:

\(x = \frac{-5.149 + 0.0514}{-2.660}\ or\ x = \frac{-5.149 - 0.0514}{-2.660}\)

\(x = \frac{-5.0976}{-2.660}\ or\ x = \frac{-5.2004}{-2.660}\)

\(x = 1.92\ or\ x = 1.96\)

Both values of x approximates to 2.

So:

\(x = 2\)

System Linear equation has no solution , because it is paralell lines but no intersection.

What is system linear equation?

An equation for a line is known as a linear equation. alternatively, y + 0.5x 3.5 = 0 and others. (Note that each linear equation is the same.) When multiple linear equations interact, we get a system of linear equations.

Here the given system linear equations,

\(3y=\frac{3}{2}x+6\) -------> 1    and \(\frac{1}{2}y-\frac{1}{4}x=3\) --------> 2

Divide by 3  of equation 1 on both sides then,

\(y=\frac{1}{2}x+2\)  -----------> 3

Now put 3 into 2 then,

=> \(\frac{1}{4}x+1-\frac{1}{4}x=3\)

=> 1=3

Hence the given system equation has no solution , because it is paralell lines but no intersection.

Answer:

  x ≈ {-2.80176, -0.339837}

Step-by-step explanation:

Write in terms of sine and cosine:

  sec(x) -5tan(x) -3cos(x) = 0 . . . . . . given, subtract 3cos(x)

  1/cos(x) -5sin(x)/cos(x) -3cos(x) = 0

Multiply by cos(x). (Note, cos(x) ≠ 0.)

  1 -5sin(x) -3cos(x)² = 0

Use the trig identity to write in terms of sin(x).

  1 -5sin(x) -3(1 -sin²(x)) = 0

  3sin(x)² -5sin(x) -2 = 0 . . . . . . . . quadratic in sin(x)

  (sin(x) -2)(3sin(x) +1) = 0 . . . . . . factor the quadratic

Values of sin(x) that make this true are ...

By using compound interest formula, we can say that about 14,688 Starbucks shops in the US in 2020.

What is compound interest?

Compound interest is a type of interest that is calculated on both the principal amount and the accumulated interest of an investment or loan. It is different from simple interest, which is calculated only on the principal amount.

To find out how many Starbucks shops there should be in 2020, we can use the formula for compound interest:

A = P (1 + r/n)^(n*t)

Where:

A = the final amount (the number of Starbucks shops in 2020)

P = the initial amount (the number of Starbucks shops in 2005)

r = the annual interest rate (6% or 0.06)

n = the number of times interest is compounded per year (1, since it's compounded annually)

t = the time in years (15, from 2005 to 2020)

Plugging in the values, we get:

A = 7,302 (1 + 0.06/1)^(1*15)

A = 7,302 (1.06)^15

A = 7,302 (2.011357)

A = 14,687.85

Rounding this to the nearest whole number, we get:

There should be about 14,688 Starbucks shops in the US in 2020, assuming the annual growth rate of 6%.

Given the equations a × b = 5742 × 6368, a × c = 5748 × 6362, and c × b = 5738 × 6372, we need to determine the relationship between the three variables a, b, and c.

By comparing the given equations, we notice that the numbers on the right-hand side of each equation are very close to each other, differing only by small amounts. This suggests that a, b, and c are approximately equal.Since a × b, a × c, and c × b involve the same numbers with slight variations, we can conclude that a, b, and c are all very close in value.

Therefore, the inequality we can infer from this information is a ≈ b ≈ c, indicating that a, b, and c are approximately equal.

In simple terms, based on the given equations, it suggests that the values of a, b, and c are very similar or approximately equal to each other.

Answer:

S₇ = 514.75

Step-by-step explanation:

the nth term of a geometric sequence is

\(t_{n}\) = a\(r^{n-1}\)

where a is the first term and r the common ratio

given t₂ = 24 and t₅ = 81 , then

ar = 24 → (1)

a\(r^{4}\) = 81 → (2)

divide (2) by (1) to eliminate a

\(\frac{ar^{4} }{ar}\) = \(\frac{81}{24}\)

r³ = \(\frac{81}{24}\) ( take cube root of both sides )

\(\sqrt[3]{r^{3} }\) = \(\sqrt[3]{\frac{81}{24} }\)

r = 1.5

substitute r = 1.5 into (1) and solve for a

a × 1.5 = 24 ( divide both sides by 1.5 )

a = 16

the sum to n terms of a geometric sequence is

\(S_{n}\) = \(\frac{a(r^{n}-1) }{r-1}\) , then

S₇    = \(\frac{16((1.5)^{7}-1)) }{1.5-1}\)

      = \(\frac{16(17.0859375-1)}{1.5-1}\)

     = \(\frac{16(16.0859375)}{0.5}\) ( divide 16 by 0.5 )

     = 32 × 16.0859375

     = 514.75
