Answer:

2x*-3x-5

* = squared

Step-by-step explanation:

step 1: distribute “x” to “2x+1”

-you now have the equation: 2x*+1x-4x-5

step 2: combine like terms (combine “1x” and “-4x”. that gets you “-3x”.)

-you now have the equation: 2x*-3x-5

step 3: you have no more like terms, your equation is solved.

final equation: 2x*-3x-5

There will be more than a percentage of 33 % of households that have an interfaith marriage from 2017 onwards.

In this problem we find a linear equation that models the percentage of households with an interfaith marriage in time. The expression indicates that the percentage increases uniformly in time. Herein we must look up for the year, from which the percentage is at least 33 % greater. Then:

I = (1 / 4) · x + 23

(1 + 33 / 100) · 23 = (1 / 4) · x + 23

30.59 = (1 / 4) · x + 23

(1 / 4) · x = 7.59

Step-by-step explanation:

per the laws of intersecting lines the angles on one side of any of the lines must be the same as the angles on the other side of that line - just left-right mirrored.

for that reason, CGE = DGF.

also to remember : the sum of all angles around a point on one side of a line is always 180° (because they represent a half-circle with that point being the center). in other words, these angles are supplementary (together 180°).

therefore,

180 = 62 + 32 + DGF

DGF = CGE = 180 - 62 - 32 = 86°

Answer:

5x + 7

Step-by-step explanation:

8x + 8 + 2x + 7 = 10x + 15

15x + 22 - (10x + 15) = 5x + 7

The expression can be simplified through division of the exponential (power).

In the given expression, if the powers have the same base, we can actually divide the power.  In order to carry out the division of the exponential (power), we can subtract their exponential.

In the general form, a-m=1/am

As there are two different base terms x and y in the numerator and denominator, we will subtract the powers of x terms and powers of y terms.

Let us simplify the x terms,

x¹/₂÷x³/₄=x(1/2)-(3/4)  

Solving the powers,(½)–(¾)=(2/4)–(¾)=(2-3)/4=-1/4

x¹/₂÷ x³/₄=x(1/2)-(3/4)= x-1/4  

Let us simplify the y terms,

y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)

Solving the powers, (-1/3)-(1/2)=(-2/6)-(3/6)=-5/6

y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)=y-5/6

Putting the terms together gives us,

x-1/4 *y-5/6

It can be expressed as a fraction as a-m=1/am

x-1/4 *y-5/6=1/x1/4y5/6

Hence, x¹/₂ y⁻¹/₃ / x³/₄ y¹/₂= x-1/4 *y-5/6=1/x1/4y5/6

Answer:

The resultant expression is 48 + 30 = 6 (8 + 5) = 6 (13) = 78.

Step-by-step explanation:

It is given that the GCF of 48 and 30 to write the sum of the two numbers as the product of their GCF and another sum.

Now,

The largest number that can divide two numbers is known as the GCF. The formula for 48 plus 30 is as follows;

=> 48 + 30

=> 6 (8 + 5)

=> 6 (13)

=> 78

Here, the numbers are given as 48 and 30 so, the expression is;

=> 48 + 30

And their GCF is 6 so, we get;

=> 48 + 30 = 6 × 8 + 6 × 5

=> 48 + 30 = 6 (8 + 5)

=> 48 + 30 = 6 (13)

=> 48 + 30 = 78

Therefore, the resultant expression is 48 + 30 = 6 (8 + 5) = 6 (13) = 78.

The value of given expression for x=0 is 0, x=-2 is -20 and x=2 is 20.

Given the expression is (10x)⁺¹.

Firstly, we will simplify the given expression (10x)⁺¹ for x=0.

Substitute the value x=0 in given expression, we get

(10x)⁺¹=(10×0)⁺¹

As we know that something multiply to zero is 0.

So, we get

(10x)⁺¹=0

Now, we will simplify the given expression (10x)⁺¹ for x=-2.

Substitute the value x=2 in given expression, we get

(10x)⁺¹=(10×2)⁺¹

Now, we will know that if we multiply any number with 2 we get twice of it, we get

(10x)⁺¹=(20)⁺¹

(10x)⁺¹=20

Furthermore, we will simplify the given expression for x=-2.

Substitute the value x=-2 in given expression, we get

(10x)⁺¹=(10×(-2))⁺¹

Now, we will know that if we multiply any number with 2 we get twice of it, we get

(10x)⁺¹=(-20)⁺¹

(10x)⁺¹=-20

Hence, the value of expression (10x)⁺¹  for x=0, 2 and -2 is 0, 20 and -20.

The point-slope equation of something like the line, with slope equal to 5/6 but instead passing through the point at(22 , 12), is:

(y - 12) = 5/6(x - 22).

A line's equation can be stated in three different ways:

The typical form of a line equation is ax + by = c, where a but rather b are the coefficients of variables x and y, respectively, as well as c is a constant if all possible values must be integers. In the meantime, the slope-intercept form is given by the formula y = mx + b, where m is the line's slope as well as b is the y-intercept. Given the slope m and a point on the line (x, y), we can formulate the equation using point-slope form, (y - y1) = m. (x - x1).

To build up the equation, use the point slope form and enter in the values.

(y - y1) = m(x - x1)

where;

m = 5/6

(x1 , y1) = (22 , 12)

(y - 12) = 5/6(x - 22)

In slope-intercept form, the equation of the line is:

(y - 12) = 5/6(x - 22)

y - 12 = 5/6 x - 110/6

y = 5/6 x - 19/3

In standard form, the equation of the line is:

y = 5/6 x - 19/3

5/6 x - y = 19/3

Multiplying both sides by 6,

5x - 6y = 38.

The point-slope equation of something like the line, with slope equal to 5/6 but instead passing through the point at(22 , 12), is:

(y - 12) = 5/6(x - 22).

All the roots of the polynomial 2x⁴+ x³-8x²- 4x = 0 are x = -2, x = -0.5, x = 0, x = 2 ( Option A ).

Given polynomial :

2x⁴+ x³-8x²- 4x = 0

The highest power of the polynomial is 4. This implies that this polynomial will have 4 roots or 4 zeroes.

There are numerous ways of finding roots or zeroes of a polynomial of any degree.

A root or zero of a polynomial is a solution or value of the variable which gives the value of the polynomial equal to 0.

Since this is a multiple choice based question, the easiest approach to this question is by eliminating options and finding the correct answer.

Option B and C get eliminated instantly because they have only three roots, however this is a polynomial of degree 4 and should have 4 roots.

For option A and C, we put x= -2, x = -0.5, x = 0, x = 2, and x = 0.5 in the given polynomial to check if the answer is equal to zero.

For x = -2, we get 2x⁴+ x³-8x²- 4x = 0

For x = 2, we get 2x⁴+ x³-8x²- 4x = 0

For x = 0, we get 2x⁴+ x³-8x²- 4x = 0

For x = -0.5, we get 2x⁴+ x³-8x²- 4x = 0

For x = 0.5, we get 2x⁴+ x³-8x²- 4x = -3.75

From this result, option C gets ruled out and all the values in option A check out as a root of the given polynomial.

Therefore, we get all the roots of the polynomial 2x⁴+ x³-8x²- 4x = 0 as x = -2, x = -0.5, x = 0, x = 2

The function y = 100 ( 0.25 ) ˣ is an exponential decay function.

An exponential function is defined as y = a ˣ where x is a variable, and a is a constant called the base of the function.

We are given a function:

y = 100 ( 0.25 ) ˣ

We need to tell whether is is a exponential growth or decay function.

We can see that the value of a ˣ = (0.25) ˣ

So, the value of a = 0.25.

Since, it is a decimal and not an integer, its value will decrease with the increase in exponent x.

So, it will be a exponential decay function.

Therefore, we get that, the function y = 100 ( 0.25 ) ˣ is an exponential decay function.

We have to find the x corresponding to f(x) = 24

For our convenience, let f(x) = y

This equation implies y in terms of x.

Isolating x to one side of the equation, we get,

x = (y - 8)/-4 = (8-y)/4

Option A, 65 + |−5| = 70°, 65° is the farthest from 0°

Here, we are given that.

The average temperature in the mountains is 65° in April.

The average temperature in that same spot is −5° in December.

Thus, the difference in the temperature will be-

65 - (-5)

= 65 + 5

= 70°

Therefore, this location is 70° warmer in April than in December.

Now, their distance from 0 will be-

|65 - 0| = 65

as distance cannot be negative, we look at only the absolute difference.

Similarly |-5 -0| = 5

Thus, we see that 65° is the farthest from 0°.

Priti chose a green coloured square paper of 20.5cm, since its a square the length and breadth of the card are equal

l = b

Recall the area of a square is

A = l^2

A = (20.5)^2

A= 20.5 × 20.5

A= 400.25cm^2

Since the paper is to be used for 5 cards, therefore the is divided in 5 equal cards. The are area of each card will be

A = A/5

A = 400.25/5

A = 80.05cm^2

The edge of each card is the side of the each card which can either be the length or the breadth since all the sides are equal for a square.

Recall that

A = l^2

Since the Area of each card is 80.05cm^2. Therefore,

80.05 = l^2

Finding the square root of both sides

(80.05)^1/2 = (l^2)^1/2
