Answer:
6
Step-by-step explanation:
1. re-write the given system:
cx+3y=c-3; => y= -cx/3 +(c-3)/3
12x+cy=c; => y= -12x/c+c/12
2. according the condition the rule for the parallel graphs is:
-c/3= -12/c
3. to calculate the unknown 'c':
c²=36; ⇔c=±6
Answer:
(-3,2)
Step-by-step explanation:
(6×5) + (6×2) = 6×7
It works if you think about it like this:
5 sixes + 2 sixes = (5 + 2) sixes = 7 sixes
This is an example of the <em>distributive property</em>.
To put it simply, we're applying the same multiplication (×6) to two different things which are being added together (5+2).
Here's another example of the distributive property:
2×(3+4) = 2×3 + 2×4
Answer: 5
<u>Step-by-step explanation:</u>
f(5) = 2 means that when x = 5, y = 2 --> (5, 2)
f⁻¹(2) is the inverse (when the x and y are swapped) --> when x = 2, y = 5
We have an equation and we know the values of the variables p, r, and t.
Plug in the values.
I = (8000)(0.6)(1)
I = 4800
So, I is equal to 4800.
