Answer:
x = 8.75, y = 8.125
Step-by-step explanation:
The triangles are similar thus the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
8x = 70 ( divide both sides by 8 )
x = 8.75
And
= 
( cross- multiply )
8y = 65 ( divide both sides by 8 )
y = 8.125
Answer:
Suppose f and g are two functions such that
1. (g ◦ f)(x) = x for all x in the domain of f and
2. (f ◦ g)(x) = x for all x in the domain of g
then f and g are said to be inverses of each other. The functions f and g are said to be
invertible.
. Properties of Inverse Functions: Suppose f and g are inverse functions.
• The rangea of f is the domain of g and the domain of f is the range of g
• f(a) = b if and only if g(b) = a
• (a, b) is on the graph of f if and only if (b, a) is on the graph of g
Step-by-step explanation:
X=2 and y=2 those are the answers
Answer:
Obtuse
Step-by-step explanation:
Plugging the numbers into the Pythagorean Theorem (a^2 + b^2 = c ^2)
20^2 = 12^2 + 15^2
400 > 144 + 225
400 > 369
Because of the Converse of the Pythagorean Theorem, which tells us if c is greater than a+b, it is obtuse
The slope of this trend line is m = (0-28) / (14-0) = -2. The y-intercept can be read directly from the graph: It is 28. Thus, the equation of this trend line is k = -2J + 28.
