Answer:

x = 5, y = 6

Step-by-step explanation:

For the triangles to be congruent then corresponding sides are equal

that is BC = ED and AC = AD, that is

x = y - 1 → (1)

3x - 2 = 2y + 1 → (2)

substitute x = y - 1 into (2)

3(y - 1) - 2 = 2y + 1

3y - 3 - 2 = 2y + 1

3y - 5 = 2y + 1 ( subtract 2y from both sides )

y - 5 = 1 ( add 5 to both sides )

y = 6

substitute y = 6 into (1) for corresponding value of x

x = 6 - 1 = 5

Which statement is true of the function f(x) = ? Select three options.
Marianna [84]

Answer:

The function has a domain of all real numbers.

The function has a range of {y|–∞ < y <∞ }.

The function is a reflection of y=∛x

Step-by-step explanation:

Given:

f(x)=-∛x

domain is set of all values that x can take for which the function is defined, so

for above function domain= set of all real numbers

range is set of values that corresponds to the set of values of domain, so for given f(x) range={y|–∞ < y <∞ } set of real numbers

Now f(x)=-∛x hence its reflection will be

-f(x)=-(-∛x)

y=∛x !
