well #7 is a solution.
y= 9x (4,36)
9 times 4 = 36
36/9=4
so the ordered pair is a solution.
y=3x-5 (7,16)
3 times 7 -5= 16
so once again the ordered pair is a solution.
Hoped this helped.
A = first dog
b = 2nd dog
a = 5 ft
a = 4/5(b)
5 = 4/5b
5/(4/5) = b
5 * 5/4 = b
25/4 = b
6 1/4 = b....ur second dog (b) = 6 1/4 ft or 6.25 ft
Answer:
the standard form of a linear equation required is B must be positive
The straight line is a polynomial. ALL polynomials have real numbers as its domain.
The exponential functions f(x) and g(x) both have the form b^x or b^(-x). Both these exponential functions have a real domain, but the range of both are limited to strictly positive numbers.
