There are no numbers without decimals which multiply to 78 and add up to 17.
Hello from MrBillDoesMath!
Answer: The domain is the set of real numbers.
the full real number system
Discussion:
f(x) = (4/5)^x is defined for all x as the underlying function (4/5)^x is defined for all x. Therefore the domain is the set of real numbers.
Thank you,
MrB
3. Here we use the formula
And we have the following values given
So we will get
Question 4.
In this question , we have
Interest is the difference of amount and principal, that is
Answer:
6x^6y^8z^6
Step-by-step explanation:
(3x^3y^4z^4)(2x^3y^4z^2)
= 6x^(3+3) y^(4+4) z^(4+2)
= 6x^6y^8z^6
Unfortunately, I can't do it on a graph here, but I will do it algebraically.
The solution on the graph will be the point of intersection of the two lines representing the equations.
y + 2.3 = 0.45x . . . . . (1)
-2y = 4.2x - 7.8 . . . . . (2)
From (2), y = 3.9 - 2.1x
substituting for y in (1), we have:
3.9 - 2.1x + 2.3 = 0.45x
2.55x = 6.2
x = 6.2/2.55 = 2.4
y = 3.9 - 2.1(2.4) = 3.9 - 5.04 = -1.2
Therefore, solution is (2.4, -1.2)
