What is the slope of the line equation 7x-3y=21

Mathematics
1 answer:
kramer3 years ago
8 0
Equation: 7x - 3y = 21

3y = 7x - 21

Divide both sides by 3, 

y = 7/3x - 7

Compare it with principle equation, y = mx + c

Here, slope (m) = 7/3

In short, Your Answer would be: 7/3

Hope this helps!

Which equation can be used to find the value of x?
Dafna11 [192]

Answer:

C

Step-by-step explanation:

We know every triangle equals 180 so were just going to take 180 - 42 = 138 then were going to do 138 - 67 = 71  we can check our work by doing

42 + 67+ 71 = 180. We also know 67 + 42 = 109.

Lets look at our answers;

A. 109 = 180 + x  When solved it gave me; x = -71. We got a positive 71 so this is incorrect.

B. x + 42 = 67   When solved it gave me;  x = 25, which is incorrect.

C. x = 180 - 109 When solved it gave me; x = 71

D. 42 + 67 - x = 180 When solved it gave me; x =  - 71

Therefore the answer is C.

What are the properties of the point (2, 0) in this graphed function?
Alex73 [517]

The point (2,0) represents a relative minimum and an x-intercept.

<h3>How to determine the property?</h3>

The missing graphed function is added as an attachment

The point (2,0) means that:

x = 2 and y = 0

On the attached graph, we can see that the graph touches the x-axis at (2,0); this represents the x-intercept

Also, the graph has a minimum at (2,0); this represents the relative minimum

Hence, the point (2,0) represents a relative minimum and an x-intercept.
