The system of equations y = 2x + 4 when graphed have a solution that y = − (1/3)x − 1 is (3, - 2)

A straight line's general equation is -

y = (m)x + c

where -

The slope of the line, [m], indicates the unit rate at which [y] changes in relation to [x].

The y-intercept, or the place where the graph crosses the [y] axis, is represented by [c].

A straight line's equation can also be expressed as -

Ax + By + C = 0

By = - Ax - C

y = \((\frac{A}{B} - \frac{B}{C})x - \frac{A}{C}\)

The set of equations is as follows:

y = − 2x + 4

AND

y = − \((\frac{1}{3} )\)x − 1

Draw the graphs for these two equations. The answer to this system of equations would be near the intersection. Please see the following graph. These lines come together at (3, - 2)

As a result, y = 2x + 4 and is the system of equations that has been solved.

y = − \((\frac{1}{3} )\)x − 1 is (3, - 2)

Anna should multiply the prices on the tags by 0.93 to find the price she would have to pay before tax in one step.

Given that Anna has a loyalty card good for a 7% discount at her local grocery store.

We have to find the number should she multiply the prices on the tags by to find the price she would have to pay, before tax

Anna should multiply the prices on the tags by 0.93 (which is 1 minus the 7% discount) to find the price she would have to pay before tax in one step.

For example, if an item costs $10 before the discount, Anna would pay $10 x 0.93 = $9.30 after the discount.

Hence, Anna should multiply the prices on the tags by 0.93 to find the price she would have to pay before tax in one step.

Answer: 3

Step-by-step explanation:

Subtract the cost of paperback books from Jonelle's total amount.

(22.50 - 4.50)

Then, you'll get ($18).

Divide (18) by the number of hardcover books.

(18/6)

Finally, you'll get $3 for the cost of each hardcover book.

The large-sample z test is appropriate for the null hypothesis H0: p = 0.1 and sample size n = 35.

For the null hypothesis H0: p = 0.1 and sample size n = 35, the large-sample z test is appropriate.

In more detail, the large-sample z test is used when the sample size is sufficiently large, typically with a sample size greater than or equal to 30. The large-sample approximation assumes that the sampling distribution of the sample proportion follows a normal distribution.

In this case, the null hypothesis states that the population proportion, denoted as p, is equal to 0.1. With a sample size of 35, which is considered large, the conditions required for the large-sample z test are met, making it an appropriate test to use for hypothesis testing in this scenario.

Step-by-step explanation:

Buying Price = $25,

Selling Price = ?

Since they sold it at a loss of 10%,

So, they sold it for a price 10% less than the buying price,

or at 90% or 0.9 of the buying price,

so,

Answer:

the degree of the polynomial

Step-by-step explanation:

Given

Polynomial equation

Required

What does the sum of the multiplicities add up to

To answer this question, I'll make use of the following polynomial.

\(p(x) = x^3 - 7x^2 + 15x - 9\)

When factorized, the polynomial is:

\(p(x) = (x - 1)(x - 3)(x-3)\)

\(p(x) = (x - 1)(x - 3)^2\)

x-1 can be expressed as \((x - 1)^1\)

So, we have:

\(p(x) = (x - 1)^1(x - 3)^2\)

The sum of multiplicity (M) of the equation is 3.

This is so because

\(x - 1\) occurred one time in \(p(x) = (x - 1)(x - 3)^2\)

\(x - 3\) occurred two times in \(p(x) = (x - 1)(x - 3)^2\)

\(Sum= 1 + 2\)

\(Sum= 3\)

The degree of \(p(x) = x^3 - 7x^2 + 15x - 9\) or \(p(x) = (x - 1)^1(x - 3)^2\) is 3.

This implies that:

\(Sum = Degree = 3\)

Hence: Option (a) answers the question

since isosceles has 2 equal sides we can add two to the shorter side

so now we multiply by 4

8 for short sides each

20 for long side

The longest side of the isosceles triangle is 20 units.

An isosceles triangle in geometry is a triangle with two equal-length sides. It can be specified as having exactly two equal-length sides or at least two equal-length sides, with the latter definition including the equilateral triangle as an exception.

Given that the perimeter of an isosceles triangle is 36 centimetres and two sides of the triangle are in the ratio $2:5.$.

The length of the longest side will be calculated as;-

2S + B = 36

S / B = 2 / 5
S = ( 2B ) / 5

2 x ( 2B ) / 5 + B = 36

4B + 5B = 180

9B = 180

B = 20 units

The measure of the other side is,

S = 2B / 5

S = ( 2 x 20 ) / 5 = 8 units

Hence, the length of the longest side is 20 units.

The correct statement is (D) at every vertex.

The vertex of a triangle is the intersection of two sides. Vertices is the term used to describe objects with several vertices.

The ability to write an equation for a line given two points is a prerequisite. The intersection of two lines will then need to be solved, which will give you the intersection's coordinates.

One of the triangle's vertices is at this intersection of two lines.

So, we know that 4 triangles are joined to make them horizontal.

This can be done when the vertex is attached to all 4 triangles.

Then, statement (D) will be a correct statement.

The trigonometric function simplified as a single expression is cosec² t .

The given trigonometric function is  : \(\frac{sin^2t+cos^2t}{sin^2t}\)

We know from trigonometric identity : that sin²t +cos²t = 1

hence the given expression simplifies to 1 / sin²t

Again trigonometric ratios states that :

1 / sin t =  cosec t

∴ 1 / sin²t = cosec² t

Hence the trigonometric function is of the form cosec² t .

The right-angled triangle's angle and the ratios of its two side lengths are connected by the trigonometric functions, which are actual functions. They are also referred to as goniometric functions, circular functions, and angle functions .

The three trigonometric functions that are used in modern mathematics the most commonly are sine, cosine, and tangent. The less frequent cotangent, cosecant, and secant are their reciprocals.

Step-by-step explanation:

It is true that the existence of two local maxima does not guarantee the presence of a local minimum. It is possible for a function to have multiple local maxima and no local minimum.

For example, consider the function f(x,y) = x^4 - 4x^2 + y^2. This function has two local maxima at (2,0) and (-2,0), but no local minimum. Therefore, the statement "if f(x,y) has two local maximal, then f must have a local minimum" is false. The presence or absence of local maxima and minima depends on the behavior of the function in the immediate vicinity of a point, and cannot be determined solely based on the number of local maxima. It is possible for a function to have an infinite number of local maxima and minima, or none at all. Therefore, it is important to carefully analyze the behavior of a function in order to determine the presence or absence of local extrema.

Answer:

Row n ---> 27th term is 27.

Row T ---> 27th term is 80.

Step-by-step explanation:

To find the 27th term for the top row, row n, you will use this formula:

an = a1 + f × (n-1)

The first number = 1

The common difference (f) = 1

a27 = 1 + 1 × (27-1)

a27 = 1 + 27 - 1

a27 = 28 - 1

a27 = 27

So, the 27th term is 27.

We will do the same for the row T.

an = a1 + f × (n-1)

The first number = 2

The common difference (f) = 3

a27 = 2 + 3 × (27-1)

a27 = 2 + 81 - 3

a27 = 83 - 3

a27 = 80

So, the 27th term is 80.
