-24
Step-by-step explanation:
substitute by 2
2²-12×2+q=0
q=-24
7.980 divide by 0.19 is 42.
Answer:
In the pic
Step-by-step explanation:
First of all, in order to solve it you need to find the dots where the function crosses x line and y line.
Then, I named each dot according to the formula.
After that, it's just simple math.
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
Given that <span>C = { X | X + 6 = 10}
This can be interpreted grammatically as "C is a set X such that X is the solution to X + 6 = 10".
Given that X + 6 = 10
X = 10 - 6 = 4
Therefore, the solution is
C = {4}

Set them up like this example:
4 8
_ = _
6 12
cross multiply by multiplying 4 by 12 and 6 by 8.
If they are equal then it is proportional.
