D > 125 or you could write it backwards 125< d
The time(h), would be the independent variable and the temperature(C) would be the dependent variable.
By checking all the sets of the real field, the number √50 is an irrational number.
<h3>What real set does a number belong to?</h3>
In this problem we know that an real element is √50. Real numbers are a set formed by the following subsets:
- Natural numbers - Its set is formed by the following elements: {1, 2, 3, 4, 5, 6, ...}.
- Integers - Its set is product of the union of all the natural numbers, the number 0 and the additive inverses of the natural numbers.
- Rational numbers - It is the product of elements of the form m / n, where m, n are integers and n is distinct from 0. These elements may be integers or not.
- Irrational numbers - Its elements are not rational.
Square roots are examples of irrational numbers. Thus, by checking all the sets of the real field, the number √50 is an irrational number.

Answer :6x + 5y = 30
5y = 30 - 6x
y = 6 - (6/5) x
So slope = -6/5
Perpendicular line has slope 5/6 (product of the slopes is -1)
So y = 5/6 x + b
Passed through (-6, -7) so -7 = -5 + b
Sp b = -2
So y = (5/6)x - 2

Answer:
25/16
Step-by-step explanation:
(4/5)^−2
=
(4/5)^−2
=
(5/4)^2
=
(5/4)*(5/4)
=
5*5/4*4
=
5^2/4^2
=
25/16
