Answer:
25k x 3
Step-by-step explanation:
You can use Desmos to graph these and make your own judgment as to the intercepts and rates of increase/decrease.
The ones with a base < 1 will decrease rapidly, then slowly. The one with a base > 1 will increase slowly, then rapidly. The y-intercept is the multiplier in front of the base.
Yay! I'm so glad that this system of linear equations has to be solved by substitution because it is my favorite way to solve these kinds of problems. I will explain how to do this problem step by step, just like I learned in 8th grade. I hope this makes sense to you :)
Step 1: Solve for either x or y in one of the two equations.
-4x - 2y = -14
+ 4x + 4x
---------------------------
-2y = 4x - 14
------ ------ ------
-2 -2 -2
y = 2x + 7
Step 2: Plug in the solution you got for x or y into the equation you have not worked with yet. (2x + y = 7)
2x + 2x + 7 = 7 ⇒ 4x + 7 = 7
- 7 - 7
--------------------
4x = 0
----- -----
4 4
x = 0
Step 3: Plug in the solution you got in step 2 into either of the 2 equations.
2(0) + y = 7 ⇒ 0 + y = 7
- 0 - 0
----------------------
y = 7
The final solution to a systems of linear equations is written in a coordinate pair. (x,y)
In your case, the final answer would be (0, 7).
Well, we need the information of the dimensions and the volume of the sweets.
Because the volume of the cylinder is
r, radius, is half of the diameter, so 3/2=1.5
h is height
so the volume is
=
=70.65
(
, approximately)
now, let's say that each sweet has a volume of 1, we can then fit in 70 sweets. But since you forgot to give the dimentions or volume of the sweets, all i can say is: you need to divide 70.65 by the volume of the sweets!
the answer for this question is 3,4and5
