Determine the x and y intercepts 2x-3y=48

qaws [65]

Answer:

x-intercept is 24 , y-intercept is -16

Step-by-step explanation:

* Lets explain how to solve the problem

- The x-intercept is the x-coordinate of the point of intersection

between the graph of the equation and the x-axis ⇒ (x , 0)

- To find the x-intercept substitute the value of y in the equation by 0

- The y-intercept is the y-coordinate of the point of intersection

between the graph of the equation and the y-axis ⇒ (0 , y)

- To find the y-intercept substitute the value of x in the equation by 0

* Lets solve the problem

∵ 2x - 3y = 48

- To find the x-intercept substitute y by 0

∴ 2x - 3(0) = 48

∴ 2x = 48

- Divide both sides by 2

∴ x = 24

∴ The graph intersects the x-axis at point (24 , 0)

* The x-intercept is 24

∵ 2x - 3y = 48

- To find the y-intercept substitute x by 0

∴ 2(0) - 3y = 48

∴ -3y = 48

- Divide both sides by -3

∴ y = -16

∴ The graph intersects the y-axis at point (0 , -16)

* The y-intercept is -16

PLEASE HELP ME

Answer:

Broker1 with $66.

Broker2 with $54.25

Broker4 with $50

Broker3 with $47.5

Broker5 with $33.5

Explanation :

Total number of shares Cindy have : 300

Market Price per share : $25

Total price for the shares : 300 $\times$ $25

= $7500

Now ,

Case 1:

Commission provided by broker1 = 0.75%

Online fees provided by broker1 = $ 10

Total price provided by broker1= $\frac{75}{10000}\times7500 +$10$

=$66.25

Case 2:

Commission provided by broker2= 0.5%

Online fees provided by broker2=$17

Total price provided by broker2= $\frac{5}{1000}\times 7500 + $17$

=$54.5

Case 3:

Commission provided by broker 3= 0.6% for 100 0r few

Not applicable because the total shares are 300

For over 100 shares

Commission provided= 0.5%

Online fees = $10

Total price = $\frac{5}{1000}\times 7500 + $10$

=$47.5

Case 4:

For more than 100 shares

Online fees for buying and sharing= $50

Total price = $50

Case5 :

Commision for a share bought or sold = 0.05%

Online fees =$30

Total Price= $\frac{5}{10000}\times 7500 + $30$

=$33.75

Answer:

$\square\quad{y=\dfrac{1}{2}x+4}\\\\\square\quad{\dfrac{y-5}{x-2}=\dfrac{1}{2}}$

Step-by-step explanation:

The slope of a line is the same everywhere, so an equation can be written making use of that fact.

$\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}\\\\\dfrac{y-5}{x-2}=\dfrac{7-5}{6-2}=\dfrac{2}{4}\\\\\boxed{\dfrac{y-5}{x-2}=\dfrac{1}{2}}$

Cross-multiplying gives ...

2(y -5) = x -2

2y -10 = x -2 . . . eliminate parentheses

2y = x +8 . . . . . . . add 10; next, divide by 2

$\boxed{y=\dfrac{1}{2}x+4}$

These equations match choices B and D.
