Answer:

Opens up

a =  1

b =  0

c = -6

Step-by-step explanation:

y=x^2-6

This is a parabola that opens upwards (see attached graph).  

I will assume the a, b, and c are the coefficients of a parabolic equation of the form:

y = ax^2 + bx + c

Since y = x^2 - 6, the values are:

a = 1

b = 0

c = -6

The numeric value of the expression A = LW, when L = 50 and W = 15, is given as follows:

A = 750.

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

The expression for this problem is defined as follows:

A = LW.

The input values of L and W are given as follows:

L = 50, W = 15.

Then the numeric value of the expression is found replacing the lone instance of L by 50 and the lone instance of W by 15, as follows:

A = 50 x 15

A = 750.

As there is only a single multiplication operation, precedence is not relevant for this problem.

The problem asks for the numeric value of the expression A = LW when L = 50 and W = 15.

The number of maths books sold is 70 and the number of history books sold is 210.

Let no of maths book sold be x.

According to the question, the number of history books sold is three times the number of maths books sold.

Therefore the number of history books sold is 3x.

Given: Total books sold = 280

So, x + 3x = 280

Solving the equation, we get:

4x = 280

x = [tex]\frac{280}{4}[/tex]

x = 70 (Number of maths books sold)

3x = 3 × 70 = 210 (Number of history books sold)

Explanation:

The weight of A is 2/3 that of B. This flips to saying "the weight of B is 3/2 that of A". Because 3/2 = 1.5, we can then have this equation

B = 1.5A

The statement "C is 75% the weight of D" leads to the equation

C = 0.75D

----------------------------

The sum of A and B is triple that of the sum of C and D, giving us this equation:

A+B = 3(C+D)

Plug in the previous two equations we found in the previous section. Afterward, solve for the variable "A".

A+B = 3(C+D)

A+1.5A = 3(0.75D+D)

2.5A = 3(1.75D)

A = 3(1.75D)/2.5

A = 2.1D

----------------------------

Let's revisit the first equation we set up, and then apply substitution like so:

B = 1.5A

B = 1.5*2.1D

B = 3.15D

----------------------------

There's a lot of equations to keep track of. The key equations are these:

A = 2.1D

B = 3.15D

C = 0.75D

The one common factor of all these equations is the variable "D". This will be useful when setting up the ratio A:B:C:D

We'll go from the ratio

A:B:C:D

to

2.1D:3.15D:0.75D:1D

afterward we can divide all four parts by the GCF variable D, to arrive at

2.1:3.15:0.75:1

----------------------------

This last section will focus on converting each part of that ratio into integers. This is done by multiplying all four parts by 100 (as shown in the 2nd step).

Then we divide all parts by the GCF 5 to get the final reduced ratio.

2.1:3.15:0.75:1

100*2.1:100*3.15:100*0.75:100*1

An inequality is a mathematical statement that compares two expressions and expresses the relationship between them. It is represented by a symbol such as ">", "<", "≥", or "≤" and can be thought of as a generalization of an equation.

Unlike an equation, which has one unique solution, an inequality can have multiple solutions or no solution at all. The solutions of an inequality are the values that make the inequality true.

Inequalities are used to model real-world situations where there are constraints or limitations, such as determining the range of possible values for a variable. They are also used to describe relationships between variables, such as when one variable is greater than or less than another variable.

There are different types of inequalities, such as linear inequalities, quadratic inequalities, and absolute value inequalities, each with their own set of rules and methods for solving them.

cos C = cos Z

The ratio for cosine is adjacent/hypotenuse. In a right triangle, the hypotenuse is the longest side, while an opposite side is the one across from a given angle, and an adjacent side is the one next to a given angle.

Since the side marked 12 is adjacent to angle C and 13 is the hypotenuse of this triangle; so, we know that:

cos C = 12/13

Thus, because of the angles and cosines for C and Z will be the same, it makes:

1. Understand the definition of the function. A piecewise defined function is a function that is defined differently on different intervals of its domain.

2. Identify the different intervals on which the function is defined. These intervals are usually separated by vertical asymptotes, which are points where the function is undefined.

3. Determine the formula for the function on each interval. This is usually given in the problem statement, but if not, you will need to figure it out from the context.

4. Find the domain and range of each formula. The domain of a function is the set of all input values for which the function is defined, and the range is the set of all output values.

5. Determine any discontinuities in the function. These are points at which the function is defined differently on different intervals, and they will be vertical asymptotes.

6. Sketch the graph of the function by plotting points and connecting them with line segments.

7. If the function is a piecewise continuous function, Analyze it further by finding its limits, derivatives, integrals, or other properties of interest as you would with any other function.

The transformations that result in similar triangles are dilations, rotations, reflections, and translations.

A transformation that conserves the shape, but not necessarily the size, of a figure is called a similarity transformation. Rotation, reflection, and translation are rigid motions, which means they preserve both size and shape, on the other hand, dilation only ensures that the shape is preserved. As the rigid motions are congruence transformations, all congruent figures are also similar.

A similarity transformation is a dilation or a combination of rigid motions and dilations. Two geometric figures are similar if and only if there is a similarity transformation that maps one of the figures onto the other. Similar figures have the same shape but necessarily not the same size.

It is not possible to construct a triangle using the given side lengths of 2.5 cm, 3.0 cm, and 6.5 cm. This is because of the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, if we take 2.5 cm and 3.0 cm as two sides, the sum of their lengths is 5.5 cm. But the length of the third side (6.5 cm) is greater than 5.5 cm, so these three side lengths cannot form a triangle.

The solution to the system of equations, x = 7y - 3 and x + 7y = 8, is: (5/2, 11/14).

One way to solve a system of equations is to use substitution.

We can start by substituting the first equation into the second equation:

x + 7y = 8

(7y - 3) + 7y = 8

7y + 7y - 3 = 8

14y - 3 = 8

14y = 11

y = 11/14

Now that we know the value of y, we can substitute it back into the first equation to find x:

x = 7y - 3

x = 7(11/14) - 3

x = 11/2 - 3/2

x = 8/2 - 3/2

x = 5/2
