what is the slope of line 2x-3y=19.
​

The ratio of the combined volume of these pyramids to the volume of the prism as a fraction is equal to 1/3.

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × b × h

Where:

Since both pyramids have the same base area as the prism, their combined volume is given by:

Combined volume = (1/3 × b × h) + (1/3 × b × h)

Combined volume = 2/3 × b × h

Also, the volume of this prism = 1/2 × b × h

Thus, the ratio is given by:

Ratio = (2/3 × b × h)/(1/2 × b × h)

Ratio = 2/3 × 1/2

Ratio = 1/3.

6) ∠FOC is vertical to ∠EOD

7) m∠POF is complementary to M∠FOB.

8) m∠AOC = 30°

6) Vertical angles are angles that are opposite of each other when two lines cross. Thus;

∠FOC is vertical to ∠EOD

7) Given that m∠POF + M∠FOB = 90

Two angles are called complementary when their measures add to 90 degrees. Thus;

m∠POF is complementary to M∠FOB.

8)  m∠BOC = 150. Thus;

m∠AOC = 180 - 150

m∠AOC = 30° because they are supplementary angles.

9) m∠EOA = 37. Thus;

m∠FOA = 180 - 37

m∠FOA = 143° because they are supplementary angles.

10) ∠EGH is adjacent to ∠OGH

This is from definition of adjacent angles

11) ∠EGH ≅ ∠DOB

m∠HGO = 128°, m∠DOB = 180° - 128° = 52° because they are supplementary angles.

12) m∠EOA = 67°, m∠DOB = 29°. Thus;

m∠EOD = 180 - (67 + 29)

m∠EOD = 84° because sum of angles on a line is 180°

13) m∠AOD + m∠DOB = 180 means that ∠AOD is supplementary to ∠DOB.

14) ∠COF ≅ ∠DOF and so we can say that;

FO is perpendicular to CD.

Answer: See attached.

Step-by-step explanation:

   For [a], we graph the parent function (y = x²), but shift it downwards 2 units.

   For [b], we graph the parent function (y = x²), but shift it downwards 6 units, shift it to the right 2 units, and apply a compress factor of 3.

Answer:

The number that could not be a value of y if y = 4x² - 6 is -12.

Step-by-step explanation:

The value of y for which a function f(x) = y = 4x² - 6 can be determined by knowing the smallest value of y for which x is equal to zero.

So, from the equation y = 4x² - 6, we will replace the value of x with zero to determine the smallest value of y.

y = 4(0) - 6

y = 0 - 6

y = -6

Thus, any number smaller than -6 could not be a value of y for the equation y = 4x² - 6.

Therefore, we can conclude that the number that could not be a value of y if y = 4x² - 6 is -12.

The piecewise functions that are represented by the graph are; g(x) = −2, x < −2; g(x) = −2x + 6, x ≥ 1; g(x) = x/2 + 1, –2 ≤ x < 1

From the attached graph of the piecewise function, we can access each option as follows;

A) g(x) = −2x, −2 < x < 0

This is not represented by the graph because g(x) = −2x has negative slope which means it goes downward. There's also no y-intercept in g(x) = −2x.

B)  g(x) = −2, x < −2;

This is represented by the graph because g(x) = −2 is a horizontal line which is only on the left side of x = -2.

C) g(x) = x − 2, −2 < x < 1;

This is not represented by the graph because g(x) = x − 2 has y-intercept at y = -2 and slope of 1 which means that graph of g(x)= x - 2 must be going upward and crossing at y = -2.

D) g(x) = −2x + 6, x ≥ 1

This is represented by the graph because g(x) = −2x+6 satisfies the graph which is going downward.

E) g(x) = x/2 + 1, –2 ≤ x < 1

This is represented by the graph because g(x) = (x/2) + 1 satisfies the graph which is going downward.

The options are;

g(x) = −2x, −2 < x < 0

g(x) = −2, x < −2

g(x) = x − 2, −2 < x < 1

g(x) = −2x + 6, x ≥ 1

After applying algebraic analysis we find the right choices for each case, all of which cannot be presented herein due to length restrictions. Please read explanation below.

In this problem we have a rational function, whose features can be inferred by algebraic handling:

Holes - x-values that do not belong to the domain of the rational function:

x³ + 8 · x² - 9 · x = 0

x · (x² + 8 · x - 9) = 0

x · (x + 9) · (x - 1) = 0

x = 0 ∨ x = - 9 ∨ x = 1

But one root is an evitable discontinuity as:

y = (9 · x² + 81 · x)/(x³ + 8 · x² - 9 · x)

y = (9 · x + 81)/(x² + 8 · x - 9)

Thus, there are only two holes. (x = - 9 ∨ x = 1) Besides, there is no hole where the y-intercept should be.

Vertical asymptotes - There is a vertical asymptote where a hole exists. Hence, the function has two vertical asymptotes.

Horizontal asymptotes - Horizontal asymptote exists and represents the end behavior of the function if and only if the grade of the numerator is not greater than the grade of the denominator. If possible, this assymptote is found by this limit:

[tex]y = \lim_{x \to \pm \infty} \frac {9\cdot x + 81}{x^{2}+8\cdot x - 9}[/tex]

y = 0

The function has a horizontal asymptote.

x-Intercept - There is an x-intercept for all x-value such that numerator is equal to zero:

9 · x + 81 = 0

x = - 9

There is a x-intercept.

<FOH and <FGH share the end points of the chord FH

<FOH is a central angle.

<FGH touches the circumference of the circle in the on the same side of the point of angle <FOH is closest to

Therefore <FGH  is 1/2 <FOH. That is always true of central angles and the smaller angle touching the circumference that <FOH points to

The solution to the system of equations is the point of intersection of the two lines which is at; (0.88, 0.65)

The two simultaneous equations of the line are given as:

y = -²/₅x + 1 -----(1)

y = 3x – 2   -----(2)

Subtracting equation 1 from equation 2 gives;

3.4x - 3 = 0

3.4x = 3

3.4x/3.4 = 3/3.4

x = 0.88

Substitute x = 0.88 in equation 2 to get;

y = 3(0.88) - 2

y = 2.65 - 2

y = 0.65

Answer:

x = 3

y = 11

Step-by-step explanation:

Since DRWH is a parallelogram

Then ,the opposite sides are congruent

Then , DR = HW and DH = RW

………………………………………………

DR = HW

⇔ 2y + 2 = 3y - 9

⇔ 9 + 2 = 3y - 2y

⇔ 11 = y

⇔ y = 11

DH = RW

⇔ 3x + 6 = y + 4

⇔ 3x + 6 = 11 + 4

⇔ 3x + 6 = 15

⇔ 3x = 15 - 6

⇔ 3x = 9

⇔ x = 9/3

⇔ x = 3

The standard form using integers of the equation is 6y - x = 42

Note that solving in standard form means writing it as a simple equation

Given y = 1/6x + 7

Cross multiply

6 × y = x + 42
