Answer:

4^1 + 17 = 21 , which is divisible by 3. 4^k + 17 and 3 * 4^k are both divisible by 3, so 4^k + 17 + 3 * 4^k is divisible by 3 as well. 3 * (4^n + 17) would be divisible by 9

Answer:

x = -10/3

Step-by-step explanation:

−4(x−5)=−7x+10

Use the distributive property to multiply −4 by x−5.

−4x+20=−7x+10

Add 7x to both sides.

−4x+20+7x=10

Combine −4x and 7x to get 3x.

3x+20=10

Subtract 20 from 10 to get −10.

3x=−10

Divide both sides by 3.

x = -10/3

Answer:

Option (c) is correct.

Step-by-step explanation:

Given equation is :

[tex]s=\dfrac{a+b+c}{3}[/tex]

The equation can be solved for a as follows :

Step 1.

Cross multiply the given equation

[tex]3s=a+b+c[/tex]

Step 2.

Now subtract b on both sides

3s-b = a+b+c-b

3s-b = a+c

Step 3.

Subtract c on both sides

3s-b-c=a+c-c

⇒ a=3s-b-c

Step-by-step explanation:

During multiplication of matrices, the number of columns of the first matrix must be equal to the number of rows of the second matrix it is multiplying.

Therefore, we can only multiply a m×n matrix to a n×c matrix as follows;

We can only multiply (m×n)·(n×c) → Product is defined

We can not multiply (n×c)·(m×n) →∞ Product is not defined.

The value of the function for x = -1 is 19.

Given is a function f(x) = 3x² + 16 we need to find f(-1),

To find f(-1), we substitute -1 into the function f(x) and evaluate the expression.

Let's do that:

f(x) = 3x² + 16

Substituting x = -1:

f(-1) = 3(-1)² + 16

Simplifying:

f(-1) = 3(1) + 16

f(-1) = 3 + 16

f(-1) = 19

Therefore, f(-1) is equal to 19.

Answer:

Let us find the slope of the line : x+ 4y = 6

we can write it as 4y = -x +6

y = -(1/4) x + ( 6/4)

slope of the line y= mx + b is m

so here slope = m = -1/4

because we have to find a paraller line so the slope for required line would be same : -1/4

equation of the line having slope m and passing through x1 y1 is :

Y= m( X-x1) + y1

let's plug m= -1/4 x1= -8 and y1 = 5

Y= (-1/4) ( X- -8) + 5

Y= ( -1/4) ( x+8) + 5

Y= (-1/4)( X ) + (-1/4)( 8) + 5

Y= (-1/4) x + 3

Let us now work on second part :

given line is : 2x- 3y = 12

let's write it -3y = -2x +12

y= (-2/-3) x + ( 12/ -3)

Y= ( 2/3) x - 4

slope of this line is 2/3

the required line is perpendicular to it

so the slope of required line = negative resiprocal of this slope =

(-1/ slope of this line ) = -1/( 2/3) = -3/2

Equation of line with slope m= -3/2 and passing through x1= 2 and y1 = 6 is :

Y= m( X-x1) + y1

Y= ( -3/2) ( X- 2) + 6

Y= (-3/2) X - 2(-3/2) + 6

Y= ( -3/2 ) X + 9

Answer : for part 1 : Y= ( 2/3) x - 4

Answer for part 2 : Y= ( -3/2 ) X + 9

Step-by-step explanation:

x^3-8 = 0

or, x^3 = 8

or, x = 8×(1/3)

or, x = 2

All solutions to the equation are x = 2,  -1 + i√3, and -1 - i√3 two roots are complex and one root is real.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have:

x³ - 8 = 0

Using identity:

a³ - b³ = (a - b)(a² + ab + b²)

(x - 2)(x² + 2x + 4) = 0

x = 2

x² + 2x + 4 = 0

Using quadratic formula:

[tex]\rm x = \dfrac{-2 \pm\sqrt{2^2-4(1)(4)}}{2(1)}[/tex]

x = -1 ± i√3

Thus, all solutions to the equation are x = 2,  -1 + i√3, and -1 - i√3 two roots are complex and one root is real.

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

First you write out your inequality:

[tex]2b-7\geq -14+2b[/tex]

So first we will subtract 2b on both sides:

[tex]-7\geq -14[/tex]

Since they both canceled out each other we are now left with [tex]-7\geq -14[/tex]

So anyways let's add 7 to both sides:

[tex]0\geq -7[/tex]

I know this might be confusing but the answer is all real numbers.

Tip: Real numbers are, in fact, pretty much any number that you can think of. This can include whole numbers or integers, fractions, rational numbers and irrational numbers.

The required 45-45-90 degree triangle is shown, where each of the two acute angles is 45 degrees and the length of the hypotenuse is equal to the length of each leg multiplied by the square root of 2.

A right-angled triangle, also known as a right triangle, is a triangle in which one of its interior angles measures exactly 90 degrees. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs.

Here,
o construct a 45-45-90 degree triangle with leg AB, we can follow these steps:

The resulting triangle will have sides AB, BC, and AC, where AB and BC are equal in length and AC is the hypotenuse.
