The statement, "two variables vary directly or inversely" show the relationship between the variables.
(1) Vary directly.
The statement means that if one variable is increasing then, the value of the second variable is increasing as well.
(2) Vary inversely.
The statement means that if one variable is decreasing then, the value of the other one should be increasing or vice versa.
(f*g)(x)= (x+7)(1/x-13)
= (x+7)/(x-13)
so the domain ( -∞, 13)U(13,∞)
375 because 15 x 5 = 75 so 75 x 4 = 300 plus his 75. So all together the answer is 375. hope this helped.
Answer:
y = 2
Step-by-step explanation:
use slope formula:
(4 - y) / (3 - 10) = -2/7
4-y / -7 = -2 /7
cross-multiply:
7(4 - y) = (-7)(-2)
28 - 7y = 14
-7y = -14
y = 2
