The composite function is:

The domain (D) is:

The domain is the set of all possible x values. Since there are no limitations for the x-values, the domain is all real numbers.

D = (-∞, ∞).

The Range (R) is:

The range is the set of all possible y values (output values). As you can see in your table, there are no negative output values. So, the range is the positive real numbers and the zero.

R = [0, ∞).

The y-intercept of the graph is: 3,000

The slope is: -2.75

The linear equation of the graph is: y = -2.75x + 3,000.

The linear equation that represents a linear graph shows the slope (m) and y-intercept (b) of the graph and is expressed in slope-intercept form as, y = mx + b.

In the given graph:

The y-intercept (b) is the starting value, which is the point on the y-axis where the line intercepts, and it is equal to: 3,000.

Using two points on the graph, (0, 3,000) and (2, 2,450), the slope of the graph = change in y / change in x = (3,000 - 2,450)/(0 - 2) = 550/-2 = -2.75.

To write the linear equation, substitute m = -2.75 and b = 3,000 into y = mx + b:

y = -2.75x + 3,000.

Answer:

31.4 cm

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

The y-intercept is the y-value when x is zero, so the initial value.

If the initial amount of snow is 72 cm, the y-intercept is 72.

The slope is the rate of change.

If the snow is melting at a rate of 5.8 cm per day, then the rate of change is -5.8.

Therefore, the equation that models the given word problem is:

[tex]\boxed{\begin{minipage}{5.4 cm}\phantom{w}\\$y=-5.8x+72$\\\\where:\\ \phantom{ww}$\bullet$ $y$ is height of the snow in cm. \\ \phantom{ww}$\bullet$ $x$ is the time in days.\\\end{minipage}}[/tex]

To find how much snow is left after 7 days, substitute x = 7 into the found equation:

[tex]\implies y=-5.8(7)+72[/tex]

[tex]\implies y=-40.6+72[/tex]

[tex]\implies y=31.4[/tex]

Therefore, there will be 31.4 cm of snow left after seven days of warm weather.

Answer: $10

Step-by-step explanation:

original price = 25

40% = 0.4

25 * 0.4= 10

Answer:

$18.26

Step-by-step explanation:

The total price is $42.20

We want to know how much 1 of those books cost

We know that $5.67 were for her dog

So we are gonna subtract that from $42.20

$42.20-$5.67=36.53

Now your gonna divide that by 2 because she got 2 books

So 36.53/2=$18.26

1 book=$18.26

In order to find the equation of this exponential function, let's use this model for an exponential equation:

Now, using some of the points given, we can find the values of the coefficients 'a' and 'b':

So our function is:

The expresion is:

to find the intercepts with the x axis we have to rplace in the equation y = 0, so:

and we solve for x

the intersection with the x axis is -2

And for the itercepts with the y axis we replace x = 0

and we solve for y

This means that the intersepts with the y axis is -8

Step-by-step explanation:

The value of m∠Y in triangle XYZ is 99°

An equation is used to show the relationship between two or more numbers and variables.

In triangle XYZ, the angles are angle x, y and z. Hence:

∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)

Substituting:

38 + (5x -11) + (4x -45) = 180

Collecting like terms:

9x - 18 = 180

9x = 198

x = 22

m∠Y = 5(22) - 11 = 99°

m∠Y is 99°

A translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) with a scale factor of 1 / 3 are necessary to transform circle A into circle B. (Correct choice: D)

In this problem we must determine the sequence of transformations require to transform circle A into circle B. From analytical geometry we know that the equation of the circle in standard form is:

(x - h)² + (y - k)² = r²

Where:

Then, we need to apply the following rigid transformations:

Translation

f(x, y) → f(x - h, y - k), where (h, k) is the translation vector.

Dilation with center at the center of the circle

r → k · r, where k is the scale factor.

The circle A is represented by x² + y² = 3, then we derive the expression for the circle B:

f(x, y) → f(x + 5, y - 2)

(x + 5)² + (y - 2)² = 9

r → k · r

(x + 5)² + (y - 2)² = (1 / 3)² · 9

(x + 5)² + (y - 2)² = 1

Then, a translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) are necessary to transform circle A into circle B.

The percentage change of the division test is 12%.

There is a percentage increase.

Percentage change is the difference in values and the percent change from the original value to the new value.

In other words, percentage change can be defined as a percentage change in value due to changes in the old number and new number, and the values can either increase or decrease.

Percentage change is all about comparing old to new values.

The division test was 60% in the first six week.

The division test was 72% in the second six week.

Therefore,

percentage change = 72% - 60%

percentage change = 12%
