Answer:

(x + 4) (x - 9)

Step-by-step explanation:

Factor the following:

x^2 - 5 x - 36

The factors of -36 that sum to -5 are 4 and -9. So, x^2 - 5 x - 36 = (x + 4) (x - 9):

Answer: (x + 4) (x - 9)

Bev earns $2 a week for taking out her neighbor’s trash cans. Complete the table of values. Then state the domain and range.

Eduardwww [97]

Domain : $\{1,2,3,4\}$

Range: $\{2,4,6,8\}$

Explanation:

It is given that Bev earns $2 a week.

Thus, for n number of weeks, we shall multiply $2 with n.

Where $n=1,2,3,4$ is the number of weeks.

For 1 week, Bev earns $2n=2(1)=2$ ⇒ $2

For 2 weeks, Bev earns $2n=2(2)=4$ ⇒ $4

For 3 weeks, Bev earns $2n=2(3)=6$ ⇒ $6

For 4 weeks, Bev earns $2n=2(4)=8$ ⇒ $8

Thus, we can see that the domain is the number of weeks.

Hence, Domain : $\{1,2,3,4\}$

Also, the money earned is the range.

Hence, Range: $\{2,4,6,8\}$

WARRIOR [948]

<h3>Hello there today we will solve your problem</h3>

here is our equation,

$2-(3x+5y)$ ,

Now we will plug in our numbers

__________________

${\boxed{x=-3}}$
${\boxed{y=4}$

__________________

$2-(3\cdot-3+5\cdot4)$

simplify it and we get

$2-(-9+20)$

$2-11$

$-9$
