Answer:
y = (3/2)x + 3
Step-by-step explanation:
slope is rise over run so 3 up and, 2 right
y-intercept is at (3,0)
Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
- y = x/-2 → y = -1/2x
- This is equivalent to multiplying x by -1/2, so this is an example of direct variation.
(b) x + 2y = 12
- 2y = 12 - x
- y = 6 - 1/2x
- This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is <u>NOT</u> an example of direct variation.
(c) 3x - 2y = 0
- -2y = -3x
- y = 3/2x
- This follows the format of y = kx, so it is an example of direct variation.
(d) 5x² + y = 0
- y = -5x²
- This is not in the form of y = kx, so it is <u>NOT</u> an example of direct variation.
(e) y = 0.3x + 1.6
- 1.6 is being added to 0.3x, so it is <u>NOT</u> an example of direct variation.
(f) y - 2 = x
- y = x + 2
- 2 is being added to x, so it is <u>NOT</u> an example of direct variation.
The following equations are examples of direct variation:
Answer:
2
Step-by-step explanation:
81/5 = 16.2
8.5
84/5 = 16.8
8.44
So from least to greatest would be: 8.44, 8.5, 16.2, 16.8
Hope this helps and if so please leave a good rating and thanks and maybe even brainliest answer. Thank you I really appreciate it. Have a nice day!
Answer:
the volume is about 1884
Step-by-step explanation:
v of cone= 1/3(pi)r^2h
diameter to radius is 30=5.477225575051661
so 1/3(3.14)5.477225575051661^2(60)
=1/3(3.14)30(60)
=1/3(5652)
=1884
hope this helps
