Answer:
a) for all values of x that are in the domains of f and g.
b) for all values of x that are in the domains of f and g.
c) for all values of x that are in the domains of f and g with g(x)≠0
Step-by-step explanation:
a) By definition (f+g)(x)=f(x)+g(x). Then x must be in the domain of f and g.
b) By definition (fg)(x)=f(x)g(x). Then x must be in the domain of f and g.
c) By definition (f/g)(x)=f(x)/g(x). Then x must be in the domain of f and g and g(x) must be different of 0.
Answer:
7 4/5
Step-by-step explanation:
2 2/5 = 12/5
3 1/4 = 13/4
12/5 x 13/4 = 156/20 = 7 16/20
7 16/20 / 4 = 7 4/5
2/3y = 18
y = 18 / (2/3)
y = 18 * 3/2
y = 54/2
y = 27 <==
Answer:
the value of x is 4/19
Step-by-step explanation:
it is simple math. 4=19x divide 4 by 19
Answer:
A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.
