So, put your "x's" together first and then your intercepts. That should answer your question :)
The golden rule is, "Do unto others, as you would have them do unto you." Hope that I helped you. If right, can you please mark as the brainliest. Thank you.
Answer:
x = 2 | y = 3. ( 2,3 )
Step-by-step explanation:
2(3x + 3y = 15)
6x + 6y = 30
3(4x + 2y = 14)
12x + 6y = 42
- 6x. -6y. -30
6x = 12
÷ 6. ÷6
x = 2
3x + 3y = 15
3(2) + 3y = 15
6 + 3y = 15
-6. -6
3y = 9
÷3. ÷3
y = 3
Answer:
The original price of a skateboard is $64
Step-by-step explanation:
Let
x ----> the original price of a skateboard
y ----> the new price of a skateboard
we know that
The linear equation that represent this problem is equal to
y=x-15 ----> equation A
y=49 ---> equation B
substitute equation B in equation A and solve for x
49=x-15
Adds 15 both sides
49+15=x
64=x
Rewrite
x=$64
The height is increasing at the rate of (6/5π) ft/min.
It is given that Gravel is being dumped from a conveyor belt at a rate of 40 ft3/min. Also, its coarseness is such that it forms a pile in the shape of a cone whose base diameter and height are always equal.
For this, we need to find the volume of a cone. Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
The volume of a cone is - V=1/3hπr²
