The function represents an exponential growth and the y-intercept is (0,0.2)

How can you tell whether an exponential function is growing or deteriorating?

Given - y=0.2(3.8) x

For a. function, [tex]y = ab^{x}[/tex]

the function represents exponential growth if a > 0  and b > 1 .

the function represents exponential decay if a > 0 and 0> b > 1.

In either case, the y-intercept is (0,a).

From the given, a = 0.2 and b = 3.8 because 2> 0 and  b > 1 .

then the function represents an exponential growth and the y-intercept is (0,0.2)

To be the solution of all real numbers the left side expression must be the same as the right side so option (D) will be correct.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

Given the equation,

3x+6=2x+10+x-4

3x + 6 = 2x + x + 10 - 4

3x + 6 = 3x + 6

For every real number will satisfy the equation.

But the left-hand side is equal to the right-hand side.

Now,

Let's consider an equation,

2x + 3 + 4x = 6x + 2 + 4

2x + 4x + 3 = 6x + 6

6x + 3 = 6x + 6

3 = 6 since it is false it means it will not have any real solution.

Hence "To be the solution of all real numbers the left side expression must be the same as the right side".

Answer:

-1/5

Step-by-step explanation:

First:

Calculate the rise:

On this graph we go down 1 meaning our rise will be -1.

Second:

Calculate the run:

On the graph we go right 5 so the run would be 5.

Third:

We put the rise and run together to get the slope.

Hence, the answer is -1/5

Notes:

Rise means how many units you move up or down from point to point.

Run means how far left or right you move from point to point.

Up and Right= + outcome

Down and Left= - outcome

Also if your rise over run is the same number but two negative number the slope would turn into a positive.

24 - 19 = 5

5 * -3 = -15

Answer:

answer is 5

Step-by-step explanation:

[tex] - 3(x - 19) = - 15[/tex]

cancel out both sides by -3, therefore -15 will become positive

[tex] \frac{ - 3(x - 19)}{ - 3} = \frac{ - 15}{ - 3} [/tex]

then add 19 to both sides

[tex]x - 19 +19= 5 + 19[/tex]

then X will add up to 24

The sum of all exterior angles in any n-sided polygon is 360 degrees, so:

[tex]72 + 63 + 75 + x + 34 + 74 = 360 \\ x + 318 = 360 \\ x = 360 - 318 \\ x = 42[/tex]

In math, mode is the number which appears most in the data set. When dealing with this, first put all of the numbers in numerical order, least to greatest.

19, 28, 31, 36, 44, 48, 55, 59, 68, 75, 75, 82, 93

Notice how 75 appear twice and all the other numbers appear once. Therefore the mode is 75.

When the endpoint is a(n) open dot or circle, the number represented by the endpoint is not a part of the solution set.

A number line is a  vertical or horizontal line that has endpoints and it is used to represent numbers at a constant interval

The translated figure, 1 unit left and 6 units up, is given at the end of the answer.

The original figure is missing, and is given at the end of the answer.

A transformation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).

Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.

The rule for a shift of 1 unit left and 6 units up is given as follows:

(x,y) -> (x - 1, y + 6).

The coordinates of the vertices of the original figure are given by:

Answer: -9,0

Step-by-step explanation:

points of discontinuity of rational function y= x²+2 x / x²-7 x-18 is x = 9 & x = -2.

points of discontinuity:

In rational functions, points of discontinuity are defined as fractions with undefined or zero as their denominator. When the denominator of a fraction is 0, the fraction is no longer defined and shows up as a hole or break in the graph.

points of discontinuity removable:

A point on the graph that is removable discontinuity is one that may be filled in with a single value despite not existing.If an is zero for a factor in the denominator that shares a factor with a factor in the numerator, a removable discontinuity at x=a in the graph of a rational function occurs.

points of discontinuity non removable:

A function's break that cannot be repaired with a single point is referred to as a non-removable discontinuity. It cannot be filled in with a single point, a vertical asymptote (a vertical line that the graph approaches but never crosses because the function is undefined at that x-value) is non removable.

given that

[tex]y = \frac{ {x}^{2} + 2x}{ {x}^{2} - 7x - 18 } [/tex]

now take the denominator and find the factors of it.

[tex] {x}^{2} - 7x - 18 = 0[/tex]

[tex] {x}^{2} - 9x + 2x - 18 = 0[/tex]

x (x -9) + 2 (x - 9) = 0

(x - 9) (x + 2) = 0

[tex]y = \frac{ {x}^{2} + 2x}{(x - 9)(x + 2)} [/tex]

now, take common on numerator

[tex]y = \frac{2(x + 2)}{(x - 9)(x + 2)} [/tex]

cancel the common factor in both numerator and denominator

[tex]y = \frac{x}{x - 9} [/tex]

now find the points of discontinuity.

x-9=0 , x+2=0

x = +9 , x = -2

now, x = +9 and x = -2

Hence the points of discontinuity of rational function y= x²+2 x / x²-7 x-18 is x = 9 & x = -2.
