Answer:

B. BC = 18 so ∆ABC ～ ∆DEF by SAS

Step-by-step explanation:

$\bf \cfrac{AB}{DE} = \cfrac{BC}{EF}$

$\bf \cfrac{15}{10} = \cfrac{BC}{12}$
$\bf \cfrac{3}{2} = \cfrac{BC}{12}$
$\bf BC = \cfrac{3}{2} \times 12$
$\bf 3 \times 6$
$\bf BC = 18$
$\bf \angle B = \angle \: E$

So, ∆ABC ～ ∆DEF by SAS.

If h (x) = {(-2,3), (0,4), (1,6), (2, 9)}<br><br> then what set of values represent h-1 (x) ?

vfiekz [6]

Answer:

$h^{-1}(x)=\{(3,-2),(4,0),(6,1),(9,2)\}$

Step-by-step explanation:

Given: $h(x)=\{(-2,3),(0,4),(1,6),(2,9)\}$

To find: $h^{-1}(x)$

Solution:

A relation is said to be a function if each and every element of the domain has a unique image in the co-domain.

Inverse of a function exist if it is both one to one and onto.

$h(x)=\{(-2,3),(0,4),(1,6),(2,9)\}$

$h^{-1}(x)=\{(3,-2),(4,0),(6,1),(9,2)\}$

What is the factored form of the trinomial

worty [1.4K]

Answer:

which pair of numbers has a product of ac and a sum of b

ac = (-5)(-3)

sum = -8

x^2 - 5x - 3x + 15

x(x-5)-3(x-5)

(x-3) (x-5)

x=3 x=5

what is the factored form of the trinomial = (x - 3) (x - 5)

2. Factor the following:

x^2 - 8 x + 15

The factors of 15 that sum to -8 are -3 and -5. So, x^2 - 8 x + 15 = (x - 3) (x - 5):

Answer: (x - 3) (x - 5)

Step-by-step explanation:
