Please help me with this question

The y-intercept of the equation 2x - y = -3 is 3 and in ordered pair form is (0,3).

The slope-intercept formula is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the equation in the question

2x - y = -3

First, we solve form for y and reorder in slope intercept form.

2x - y = -3

Subtract 2x from both sides

2x - 2x- y = -3 - 2x

- y = -3 - 2x

Divide each term by -1

y = 3 + 2x

Reorder in slope intercept form

y = 2x + 3

To find the y-intercept, replace x with zero and solve for y

y = 2(0) + 3

y = 3

Therefore, the y-intercept is 3.

Hello! In this question, we are trying to find the percentage increase in Miss Meg's salary.

__________________________________________________________

Explanation:

From the question, we were provided the following information:

With this information, we will be able to find the percentage of increase in her salary.

__________________________________________________________

Solve:

To find Miss Meg's percentage salary increase, let us first calculate the difference between her new and initial salary.

$1760 - $450 = $1310

We now know that Miss Meg's salary increased by $1310

Using this information, we can then get her salary increase amount and divide it by her original salary.

$1310 ÷ $450 = 2.9111

Multiply 2.911 by 100 to get the decimal into percentage form to show us the percentage salary increase.

2.911 × 100 = 291.11%

This means that Miss Meg's percentage salary increase was 291.11%

discontinuity point of a function is a point at which the function is not continuous. There are three types of discontinuities: removable, jump, and essential.

A removable discontinuity is a point at which the function is not defined, but the limit of the function as x approaches the discontinuity point from both sides is equal to a finite value.

A jump discontinuity is a point at which the function is defined, but the limit of the function as x approaches the discontinuity point from both sides is not equal.

An essential discontinuity is a point at which the function is not defined and the limit of the function as x approaches the discontinuity point from both sides is infinite or does not exist.

To find the discontinuity points of a function, you can:

Plot the function on a graph and look for any breaks or gaps in the graph.

Use the algebraic definition of continuity to determine whether the function is continuous at a given point.

Use the limit definition of continuity to determine whether the function is continuous at a given point.

Use a computer algebra system (CAS) to find the discontinuity points of a function.

Yes, the given statement is true the volume of the prism is greater than the volume of the pyramid when they have same base and same height.

As given in the question,

Formula required to calculate the volume of the pyramid and volume of the prism is given by :

Volume of a pyramid = (1/3) × (base area )× ( height )

Volume of a prism = (Base area) × (height)

When the base and height of the pyramid is same as that of the base and height of the prism then

Volume of the pyramid =  ( 1/3) × ( Base area  × height )

⇒Volume of the pyramid =  ( 1/3) × ( Volume of the prism )

⇒Volume of the prism = 3 × ( Volume of the pyramid )

⇒Volume of the prism >  Volume of the pyramid

Therefore, the volume of the prism is greater than the volume of pyramid is a true statement.

The region encircled by a circle with radius r is known as πr² in geometry. Here, the Greek letter stands for the constant proportion of a circle's circumference to its diameter, which is roughly equivalent to 3.14159.

This formula, which was first discovered by Archimedes, can be derived by considering the circle as the boundary of a series of regular polygons. A regular polygon's area is equal to half its perimeter times the distance from its center to its sides. The equivalent formula,  [tex]A=\frac{1}{2} *2\pi r*r[/tex] states that the area is equal to half the perimeter times the radius.

The value of k in the quadratic equation is k = 2

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² + kx - 5/4 = 0   be equation (1)

Now , on simplifying the equation , we get

If 1/2 is the root of given equation, then it will satisfy it.

So , when x = 1/2

( 1/2 )² + k ( 1/2 ) - 5/4 = 0

( 1/4 ) + k/2 - 5/4 = 0

k/2 - 1 = 0

Adding 1 on both sides of the equation , we get

k/2 = 1

Multiply by 2 on both sides of the equation , we get

k = 2

Therefore , the value of k is 2

Hence , the value of k in the equation is 2

The multiplicity of 0 is the number of times that 0 appears as a root of a polynomial equation.

In other words, it is the number of times that 0 is a solution to the equation. For example, the equation x^2 - 4x + 4 has two solutions, 0 and 4. The multiplicity of 0 is therefore 2, since 0 is a repeated solution.

If a polynomial equation has only one 0 as a solution, the multiplicity of 0 is 1. In some cases, a polynomial equation may have no 0s as a solution, in which case the multiplicity of 0 is 0.

In general, the multiplicity of a number is the number of times it appears as a solution to a polynomial equation. For example, the equation x^2 - 2x + 8 has two solutions, 2 and 4. The multiplicity of 2 is 1, since 2 appears only once as a solution, while the multiplicity of 4 is 2, since 4 appears twice as a solution.

A function increases if the output value of function increases on increasing the input value and the function decreses if the output value of function decreases on increasing the input value

As we know a function is nothing but a relation between input values and output values where each input has exactly one output.

Consider a function y = f(x)

For a given function if the value of y increases on increasing the value of x, then the function is an increasing function

If the y-value decreases on increasing the value of x, then the function is a decreasing function.

Another method is that if we need to determine whether a function f(x) is increasing or decreasing at point 'a'.

If a function is differentiable on an open interval, we calculate the derivative of function f(x)

If the derivative f′(x) > 0 on an open interval, then function f(x) is increasing on that interval.

If the derivative f′(x) < 0 on an open interval, then function f(x) is decreasing on that interval.

Therefore, if the output value of function increases on increasing the input value then the function is an increasing function and if the output value of function decreases on increasing the input value then the function is an decreasing function.

where x is the number of days

Answer:

1. 7.75 = 2.25 + 0.25(x)

7.75 - 2.25/ 0.25 = x

x = 20

2. 2.25+0.25(25) - 2.25 +0.25(14)

= 9.75

3. 2.25 + 0.25(10)

= 4.75

I hope i explained it well...

( i ) 21st day he saves 7.75

(ii) the difference between the amount saved by Rajiv on the 25th day and the 14th day is 2.75 rupees.

(iii) the sum of the amount saved in the first 10 days is 5 rupees.

Solution: (i)  given: on each succeeding day he increases his saving by 25 paise.

                2.75 rupees he saves on the  first day

        so    = 2.75 +(0.25×20)

                = 2.75+5

                = 7.75 rupees

         (ii)   amount saved by Rajiv on the 25th day is:

                = 2.75+(0.25×24)

                = 2.75 + 6

                = 8.75

               amount saved by Rajiv on the  14th day is :

                =2.75+(0.25×13)

                =2.75+3.25

                =6

therefore the difference between Rajiv' saving on the  25th day and the  14th day   is :         =   8.75-6                                    

                     =     2.75

          (iii)   the sum of the  amount saved in the first 10 days is :

                =  2.75+(0.25 ×9)
