Inequality y 5x - 7 has solutions (-5, -3), (-4, 2), and (-1, 0).

In order to address an inequality • You can multiply or divide each side by the same positive amount; • You can add the same amount to each side; • You can take the same amount away from each side. If you multiply or divide each side by a negative value, the inequality sign must be reversed.

Let's examine each point individually:

(-5, -3)

y ≥ 5x - 7

-3 ≥ 5(-5) - 7

-3 ≥ -32

The inequality is true, so (-5, -3) is a solution.

(-4, 2)

y ≥ 5x - 7

2 ≥ 5(-4) - 7

2 ≥ -27

The inequality is true, so (-4, 2) is a solution.

(1, -2)

y ≥ 5x - 7

-2 ≥ 5(1) - 7

-2 ≥ -2

The inequality is not true, so (1, -2) is not a solution.

(-1, 0)

y ≥ 5x - 7

0 ≥ 5(-1) - 7

0 ≥ -12

The inequality is true, so (-1, 0) is a solution.

(3, 0)

y ≥ 5x - 7

0 ≥ 5(3) - 7

0 ≥ 8

The inequality is not true, so (3, 0) is not a solution.

(4, 1)

y ≥ 5x - 7

1 ≥ 5(4) - 7

1 ≥ 13

The inequality is not true, so (4, 1) is not a solution.

Step-by-step explanation:

The arithmetic sequence has a common difference d = 9 which is the difference between successive terms

The sum of the first n terms of an arithmetic sequence is given by
[tex]S_n = \dfrac{n(a_1 + a_n)}{2}[/tex]

The nth term of an arithmetic sequence is given by
aₙ = a₁ + d(n - 1)

where a₁ = first term

In this particular sequence, a₁ = 13 and d = 9

Therefore
a₃₃ = 13 + 9(33-1)
= 13 + 9(32)

= 13 + 288

= 301

Answer:

Let's use algebra to solve the problem.

Let x be the first number.

Let y be the second number.

From the problem, we can set up two equations:

"One number is less than 3 times another":

x = 3y - - - (Equation 1)

"Their sum is increased by 5 the result is 25":

x + y + 5 = 25

x + y = 20 - - - (Equation 2)

Now we have two equations with two unknowns. We can use substitution or elimination to solve for one of the variables.

Using substitution:

From equation 1, we know that x = 3y. We can substitute this into equation 2 to eliminate x:

3y + y = 20

4y = 20

y = 5

Now we can substitute this value of y back into equation 1 to find x:

x = 3y

x = 3(5)

x = 15

Therefore, the first number is 15 and the second number is 5.

Answer: Let's call the first angle "x".

From the problem statement, we know that the second angle is two times the first, so:

Second angle = 2x

We also know that the third angle is 170° more than the second angle, so:

Third angle = Second angle + 170°

Third angle = 2x + 170°

We know that the sum of the three angles in a triangle is 180°, so we can set up an equation:

x + 2x + (2x + 170°) = 180°

Simplifying and solving for x:

5x + 170° = 180°

5x = 10°

x = 2°

So the first angle is 2°. Using this value, we can find the other two angles:

Second angle = 2x = 2(2°) = 4°

Third angle = 2x + 170° = 2(2°) + 170° = 174°

Therefore, the three angles in the triangle measure 2°, 4°, and 174°.

Here we are given the matrix A, and we want to find the transpose matrix A^t.

To do so, just leave the elements in the diagonal as they are in the original matrix, and then do a "reflection" of the other elements along the diagonal line. So the elements with equal subindices stay where they are, and the others are reflected along them.

Then the new matrix will be:

There are 2 ounces of jam in the large jar and 2/3 ounce of jam in each small jar.

In mathematics, a matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns. Matrices are commonly used to represent and manipulate linear transformations and systems of linear equations.

The elements of a matrix are typically denoted by lowercase letters with subscripts, such as aij or bij, where i and j refer to the row and column indices, respectively. For example, a 3x3 matrix might look like this:

| a11 a12 a13 |

| a21 a22 a23 |

| a31 a32 a33 |

This matrix has three rows and three columns, and the element in the first row and second column is denoted by a12.

Matrices can be added, subtracted, multiplied, and divided, and these operations follow specific rules that are defined in matrix algebra. For example, to add or subtract two matrices of the same size, we simply add or subtract the corresponding elements. To multiply two matrices, we multiply the rows of the first matrix by the columns of the second matrix and sum the products.

Let's represent the number of ounces of jam in the large jar as "L" and the number of ounces of jam in each small jar as "S". Then we can write the system of equations:

1L + 2S = 8

1L - 1S = 2

We can write this system in matrix form as:

[1 2; 1 -1][L;S] = [8;2]

To solve for L and S, we can use matrix algebra to isolate [L;S]:

[L;S] = [1 2; 1 -1]⁻¹ [8;2]

First, we need to find the inverse of the coefficient matrix [1 2; 1 -1]. The inverse is:

[1 -2; 1 1]/3

So we can substitute this into our equation:

[L;S] = [1 -2; 1 1]/3 [8;2]

[L;S] = [2;2/3]

So there are 2 ounces of jam in the large jar and 2/3 ounce of jam in each small jar.

For the function g, the vertex form equation is [tex]g(x) = -2(x - 5)^{2} + 9.[/tex]

In algebra, the idea of an equation is a logical assertion that shows the equivalence of several mathematical expressions. For instance, the equations 3x + 5 & 14, that are separated by the 'same' sign, make up the equation 3x + 5 = 14.

A mathematical equation, such as 6 × 4 = 12 x 2, states that two quantities or values are equivalent. a meaningful noun. Equations are used when more than one factor has to be considered in order to fully understand or explain a situation.

Substituting the first point (7,1) into the equation for g(x), we get:

[tex]1 = a(7 - 5)^{2} + 9[/tex]

we get

[tex]-8 = 4a[/tex]

Dividing both sides by 4,

[tex]a = -2[/tex]

Now that we have found the value of a, we can write the equation for g(x) as:

[tex]g(x) = -2(x - 5)^{2} + 9[/tex]

Answer:

Primero, podemos establecer las siguientes ecuaciones:

La suma de los kilómetros que caminan Mateo y Leo es igual a 15:

 Mateo + Leo = 15

Mateo camina 1/5 más que Leo:

 Mateo = Leo + 1/5Leo

 Mateo = 6/5Leo

Podemos utilizar la segunda ecuación para despejar una de las variables en términos de la otra. Por ejemplo, despejando Leo:

   Leo = 5/6Mateo

Luego, podemos sustituir esta expresión en la primera ecuación para obtener una ecuación con una sola variable:

   Mateo + 5/6Mateo = 15

   11/6Mateo = 15

   Mateo = 15*6/11

   Mateo = 8.18 Km

Finalmente, podemos utilizar una de las ecuaciones que relaciona a Mateo y Leo para obtener la distancia que recorre Leo:

   Leo = 5/6Mateo

   Leo = 5/6*8.18

   Leo = 6.82 Km

Por lo tanto, Mateo recorre 8.18 Km y Leo recorre 6.82 Km.

So, after 4 years, a £230 investment will be worth roughly £283.52 at a 5% yearly income rate compounded annually.

Let's assume you spend $1,000 (your capital) and it makes 5% once a year in interest or profits (the compounding frequency). You would've had $1,050 at the end of the first year, which is your initial capital plus an additional $5, or $50. You would also have $1,102.50 in the following year.

We can use the compound interest algorithm to find a solution to this issue:

[tex]A=P\left(1+\frac{r}{n}\right)^{n t}[/tex]

where A is the final amount, P is the initial investment, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time in years.

In this case, we have:

P = £230 (the initial investment)

r = 5% = 0.05 (the annual interest rate as a decimal)

n = 1 (since the interest is increased yearly) (since the interest is compounded annually)

Given that we're searching for a number after four years, t = 4.

With these numbers entered into the algorithm, we obtain:

A = 230(1 + 0.05/1)⁴

A = 230(1.05)⁴

A = £283.52

Step-by-step explanation:

To simplify the expression 24 + b/b + 24 x 53.72, we first need to substitute the given value of b into the expression. For example, if b is equal to 5, we can replace all instances of b with 5 to get 24 + 5/5 + 24 x 53.72. Next, we can simplify the division by evaluating 5/5, which equals 1. Then, we can multiply 24 and 53.72 to get a product of 1288.28. Finally, we can add the simplified terms to get a final result of 1312.28. Therefore, the simplified expression, given that b is equal to 5, is 1312.28.

Answer:

a) To calculate how much Vanessa will have to pay back after 2 years, we need to add the interest to the principal.

The interest can be calculated using the simple interest formula:

Interest = Principal x Rate x Time

where,

Principal = $5,000 (the amount borrowed)

Rate = 4% (expressed as a decimal, 0.04)

Time = 2 years

So,

Interest = $5,000 x 0.04 x 2

Interest = $400

The total amount Vanessa will have to pay back is the sum of the principal and the interest:

Total amount = Principal + Interest

Total amount = $5,000 + $400

Total amount = $5,400

Therefore, Vanessa will have to pay $5,400 after 2 years.

b) To calculate how much interest Vanessa will pay, we can use the same formula for simple interest:

Interest = Principal x Rate x Time

Plugging in the given values, we get:

Interest = $5,000 x 0.04 x 2

Interest = $400

Therefore, Vanessa will pay $400 in interest over the 2-year period.
