y = -0.4x + 6.3
B.
y = -7.4x + 0.7
C.
y = -0.7x + 7.4
D.
y = -6.3x + 0.4

Answer:

no sign (not positive or negative)

Step-by-step explanation:

The value of the expression

4.3 ⋅ (-3.2) ⋅ 0

is 0, as the value of any number multiplied by zero is 0.

The number zero is neither positive or negative; hence there is no sign.

Answer:

Domain and Range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively

Step-by-step explanation:

We have the functions, f(x) = eˣ and g(x) = x+6

So, their composition will be g(f(x)).

Then, g(f(x)) = g(eˣ) = eˣ+6

Thus, g(f(x)) = eˣ+6.

Since the domain and range of f(x) = eˣ are all real numbers and positive real numbers respectively.

Moreover, the function g(f(x)) = eˣ+6 is the function f(x) translated up by 6 units.

Hence, the domain and range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively.

Step-by-step explanation:

i had answered saying it was D but then I got it wrong, so I can't just delete my answer. But I can say it is absolutely not D.

For stuff like this you have to simplify the equation and solve for x.

But since its multiple choice you can just plug in each answer until it makes the equation true.

So here are the equations with n substituted in:

8(8+1)+3=45

7(7+1)+3=45

6(6+1)+3=45

5(5+1)+3=45

Now simplify:

8(8+1)+3=45   becomes  72+3 = 45

6(6+1)+3=45   becomes 42+3=45

5(5+1)+3=45   becomes 30+3=45

Its easiest to start with the highest option given and then go down. Because 8 is already way to high you could skip doing the math for 7 and go straight to 5 and 6.

42+3=45 becomes 45=45

30+3=45 becomes 33=45

So 6 makes this statement true.

After awhile its easy to gauge what numbers will come out to be, so you don't have to do the math for each answer.

Sequence of transformation is first moving 5 unit in y axis than mirror image  with y axis.

A particular order of transformational events is referred to as a transformational sequence. This indicates that more than one transformation is handled by a series of transformations, and the order in which they happen is important.

The line of reflection must pass through the centre point for the figure to map onto itself. The sides of the figure are cut by two lines of reflection. The vertices of the figure are intersected by two lines of reflection. As a result, there are four potential lines of reflection that pass through the center.

The number of real solution varies according to the degree of the equation and the nature of the equation, The answer is dependent on degree and nature.

In mathematics, a solution refers to a value or set of values that satisfies a given equation, system of equations, or problem. For example, if the equation is x + 2 = 4, then the solution is x = 2, because substituting 2 for x in the equation makes it true. In the case of systems of equations or more complex problems, a solution may be a set of values that satisfies all the equations or conditions of the problem. In such case, the solution may be represented graphically or as coordinates of a point.

In mathematics, an ideal solution refers to a solution that meets all the desired criteria or requirements without any constraints. It is the "best case" scenario. A real solution, on the other hand, refers to a solution that takes into account all the limitations and constraints of a problem. It is a more practical and realistic solution.

example:

A linear equation (degree 1) has one real solution.

A quadratic equation (degree 2) can have either two real solutions, one real solution or no real solutions, as it depends on the discriminant of the equation, as I explained in my previous answer.

A cubic equation (degree 3) can have one to three real solutions, depending on the coefficients of the equation.

Step-by-step explanation:  it is basically the same problem with the  opisate meaning

In order for a triangle to shrink in size but stay proportional to its original size, the scale factor, K, must be between zero and one.

What is scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

In order for a triangle to shrink in size but stay proportional to its original size, the scale factor, K, must be between zero and 1.

The image is contracted if the scale factor is less than 1 (0< k <1).

The image is enlarged if the scale factor is more than 1 (k > 1).

The image remains the same if the scale factor is 1 (k = 1).

Hence, the scale factor k should be between 0 and 1.

What do you mean by function?

A relation between a collection of inputs and outputs is known as a function. In other word, it is a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.

here we are given a function h(x)

here h(x) = - 5f(g(x)) ------(i)

and we are given the value of

g(2) =3   ;   f(2) = 1     ;     g'(2) = -2

f(3) = 4   ;    f'(3) = 5    ;    f'(2) = 6.

and we need to find the value of h'(2).

here f(x), g(x) and h(x) are the function of x and f'(x), g'(x) and h'(x) denotes the derivative of f(x), g(x) and h(x) respectively.

so we are given ,

h(x) = - 5f(g(x))

differentiating with respect to x both side

h'(x) = -5 f'(g(x).g'(x).

at x =2,

h'(2) = [tex]-5*f'(g(2))*g'(2)[/tex]

and we know  g(2) = 3 and g'(2) = -2.

so,

h'(2) = [tex]-5*f'(3)*-2[/tex]

h'(2) = [tex]-5*5*-2\\[/tex]       ( as f'(3) = 5 )

h'(2) = 50

so Option C is correct, the value of h'(2) = 50.

A linear system has one solution if the slopes of the equation of lines are different.

The 3  possible solutions of a linear system are:

- Unique or one solution

- Infinite solutions

- No solution

A linear equation is equal to the equation of a line, which has the form:

y = mx +b

where m = slope

If the slopes are different, then their graphs will intercept in one point. Hence, the system of linear equation will have one solution.

Example:

2x + 5y = 34  .. .. (equation 1)

x + 5y = 32  .........(equation 2)

Change the equation 1 and equation 2 into slope-intercept form:

y = (-2/5) x + 34/5   ..... (equation 1a)

y =  (-1/5) x + 32/5   ..... (equation 2a)

The slope of equation is (-2/5) while equation 2 is (-1/5), which is different from equation 1.  Hence, the system of linear equation has one solution.

The confidence interval spans from 440 to 472. This is a width of 472-440 = 32 units. It divides in half to get 32/2 = 16. We can think of this as the "radius" of the confidence interval, and it represents the margin of error. It's the distance from the center to either endpoint of the interval.

Side note: use the midpoint formula to determine the center.
