Patrice needs to consume more than 1200 calories, but less than 1600 calories.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, Patrice is trying a low-calorie diet. She would like to keep her calories consumed between the levels shown in the following compound inequality: 2450 < 2x + 50 and 2x + 50 < 3250.

From the first inequality

2450 < 2x + 50

2400 < 2x

x > 1200

From the second inequality

2x + 50 < 3250.

2x < 3200

x < 1600

Therefore, x > 1200 and x < 1600; Patrice needs to consume more than 1200 calories, but less than 1600 calories.

For the given system of equations the value of x is 0.27 and the value of y = 2.7.

A system of equations in algebra consists of two or more equations and looks for common answers. A group of equations that have the same set of variables as solutions are referred to as a system of linear equations.

The given equations are:

-8x + 6y = 14 and

-5x + 2y = -7

For the equation -5x + 2y = -7 isolate the value of x:

-5x = 7 - 2y

x = - (7 - 2y) / 5

Substitute the value of x in the equation -8x + 6y = 14.

[tex]-8 (\frac{7-2y}{5} ) +6y =14\\\\-11.2 + 3.2y + 6y =14\\\\9.2y = 14 + 11.2\\\\y = 2.7[/tex]

Substitute the value of y in any one of the equations:

-8x + 6(2.7) = 14

-8x = 14 - 16.2

x = 0.27

Hence, the value of x is 0.27 and the value of y = 2.7.

Answer: 5 hardcover and 3 paperback

Step-by-step explanation: To solve, we need to keep this question in mind:

"How many books can we buy for each without going over the initiate amount [$26]?"

So, let's start with the $4 books, so knowing our multiples of 4

ex. 4, 8, 12, 16, 20, 24, 28......

So, I listed the example of the multiples. So, it can be either 20 or 24. So, it would be 20, because it is under the initiate amount AND it is less with unincluded paperback books. So, 26-20 = 6. So, if each paperback book costs $2, we need to divide 6 by 2. That's 3. So, therefore, she can buy 5 hardcovers and 3 paperbacks by spending all the money. I hope this helps!

On solving the provided question, we can say that by equation so he has to play 10 games at each arcade,  to spend the same amount of money at each arcade

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

the equation that we can create here is

Kabir paid an entrance of $5 plus an additional 0.75 per game at a local arcade.

he and a friend went to another arcade where kabir paid $1.25 per game, but there was no entrance fee

let kabir played 10 games.

then at arcade 1 he spends $5 + (10*0.75) = 5 + 7.5 = $12.5

The sum of all the elements of set S is -(220/7).

To express the function (x^2+5x +y)/(x^2+7x - 44) as a quotient of two linear functions, the denominator must be a factor of the numerator. In other words, (x^2+7x - 44) must divide (x^2+5x +y) without leaving any remainder. To find the sum of the elements of S, we can set the numerator equal to the denominator multiplied by a constant and solve for y.

x^2+5x +y = c(x^2+7x - 44)

The constant c is a scalar value.

x^2+5x +y = cx^2 +7cx - 44c

we can now equate the coefficients of x^2 and x.

1 = c

and, 5 = 7c

now we can solve for c:

c = 5/7

Now we can substitute the value of c back into the equation:

x^2+5x +y = (5/7)(x^2+7x - 44)

=> x^2+5x +y = (5/7)x^2 + (35/7)x - (220/7)

we can now equate the constant terms:

Using a system of equations, Christine's investments in account one were $4,000 and in account two $16,000.

A system of equations refers to simultaneous equations.

Simultaneous equations are two or more equations solved concurrently.

Total investment in two accounts = $20,000

The simple interest rate for account one, x = 8%

The simple interest rate for account two, y = 10%

Total interest for a year = $1,920

Let account one = x and account two = y

x + y = 20,000 ... Equation 1

0.08x + 0.1y = 1,920 ... Equation 2

Multiply Equation 1 by 0.08

0.08x + 0.08y = 1,600 ... Equation 3

Subtract Equation 3 from Equation 2:

0.08x + 0.1y = 1,920

-

0.08x + 0.08y = 1,600

0.02y = 320

y = 16,000

= $16,000

In Equation 1, x + y = 20,000, Substitute y = 16,000:

x + 16,000 = 20,000

x = 4,000

= $4,000

Check:

From Equation 2:

0.08x + 0.1y = 1,920

0.08(4,000) + 0.1(16,000) = 1,920

320 + 1,600 = 1,920

Thus, using simultaneous equations, we can conclude that Christine invested $4,000 in the first account and $16,000 in the second account.

What does the slope intercept form mean?

The formula for a straight line, written as y = mx + b, where m denotes the line's slope and b its y-intercept. We can see that the y-intercept of the line in our equation, y = 7 x + 4, is 4.

                   In the slope-intercept form, the equation for the line is expressed as follows: y = mx + b, where m denotes the slope and b the y-intercept. We can observe that the line's slope is 3 from our equation, y = 3 x + 5.

All lines passing thru the origin should have a slope of y = mx + c

In this case, since the slope is 1/7 ,  the line will be  y = 1/7x

Thus, it could observe which is the only point  that satisfies this equation of the line out of all the points.

For choice "E" when x= 7  and y = 14  m = 1/7 and put the value in y = mx + c  it will give 14 = 2 , which is wrong.

C. No; you would need to know that each pair of diagonals is perpendicular.

Step-by-step explanation:

It is not sufficient to establish that MNOP and TQRS are congruent parallelograms given that MO=TR and NP=QS. Parallelograms that are congruent have the same size and form. A common method for demonstrating that two parallelograms are congruent is to use one of the following criteria:

SSS (Side-Side-Side) : If all three pairs of corresponding sides are congruent.

SAS (Side-Angle-Side): If two pairs of corresponding sides and the included angle are congruent

ASA (Angle-Side-Angle): If two pairs of corresponding angles and the included side are congruent

HL (Hypotenuse-Leg): If the hypotenuse and one leg of one right triangle are congruent to the hypotenuse and one leg of another right triangle

CPCTC (Corresponding parts of Congruent Triangles are Congruent)

Given that we only know that MO=TR and NP=QS, we do not have enough information to prove that the parallelograms are congruent. It is missing information about the angles and the diagonals of the parallelograms.

In addition to that, we need to know that the diagonals of the parallelograms bisect each other. If this is the case, then we can use HL to prove that the parallelograms are congruent.
