Answer:

r = √V / Th

Step-by-step explanation:

V=Tr^2h

V / Th = r^2 ..........bring T and h on the other side as V

r = √V / Th ____ $\sqrt{V/Th}$

Which ordered pair is a solution of the equation 2x − y = 9?

gladu [14]

The correct answer is: [C]: " (5, 1) ".

__________________

Explanation:

__________________

Choice: [C]: " x = 5 " ; " y = 1 " ;

Note: Given the equation: " 2x - y = 9 " .

→ Plug in " 5 " for "x" , and " 1 for " y " ;

to get: " [2 * 5] - [1] = 10 - 1 = " 9 " ; and: " 9 = 9 " .

So, Choice: [C]: " (5, 1) " — is the CORRECT ANSWER.

__________________

Let us consider the "other answer choices" ; as follows:

__________________

Choice: [A]: "x = - 4 " , "y = 1" ; Plug in these values for the given equation:

→ " 2x - y = 9 " ;

→ " (2 * -4) - (5) = - 8 - 5 = " - 13 " ; and: " - 13 ≠ 9 " .

→ So: Answer choice: [A]: is INCORRECT.

__________________

Choice [B]: "x = -2" , "y = 5" ; Plug in these values for the given equation:

"2x - y = 9 " ;

→ " (2 * -2) - (5) = -4 - 5 = -9 ; and: " -9 ≠ 9 " .

→ So: Answer choice: [B]: is INCORRECT.

__________________

Choice: [D]: "x = 6 " , "y = - 3" ; Plug in these values for the given equation:

"2x - y = 9 " ;

→ " (2 * 6) - ( -3) = 12 - (-3) = 12 + 3 = " 15 " ; and: " 15 ≠ 9 " .

→ So: Answer choice: [D]: is INCORRECT.

__________________

→ The correct answer is: [C]: " (5, 1) " .

Does the point (-4, 3) fall on the graph of this line? How do you know? Show your work. ( 2 points) PLEASE HELP ILL MARK BRAINLI

Elanso [62]

Answer:

Step-by-step explanation:

Since we know the line goes through points $(8,9)$ and $(2,4)$ , we can construct a line in slope-intercept form

$y = mx + b$

where $m$ is the slope and $b$ is the Y-intercept.

The slope can be found using the two points provided:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

$\frac{9 - 4}{8 - 2}$

$\frac{5}{6}$

The line is now represented as

$y = \frac{5}{6}x + b$

To solve for $b$ , we can plug in one of the two points:

$y = \frac{5}{6}x + b$

$(9) = \frac{5}{6}(8) + b$

$4 = \frac{20}{3} + b$

$b = \frac{-8}{3}$

We know have our line:

$y = \frac{5}{6}x - \frac{8}{3}$

To determine if the point $(-4, 3)$ falls on this line, we just plug the numbers into the equation and see if it holds true:

$y = \frac{5}{6}x - \frac{8}{3}$

$(3) = \frac{5}{6}(-4) - \frac{8}{3}$

$3 = \frac{-10}{3} - \frac{8}{3}$

$3 = \frac{-18}{3}$

$3 = -6$

This does not hold true, so the point is not on the line.
