Valentina's family is planning to have a party for her quinceanera. They are considering two different locations to rent for her

CaHeK987 [17]

Answer:

number of hours = 3 hours

Step-by-step explanation:

Let

x = number of hours

Casa Lucia = 200 + 500x

Silver Fox = 1,100 + 200x

To solve the equation, equate both cost of rent

Casa Lucia = Silver Fox

200 + 500x = 1,100 + 200x

200 - 1,100 = 200x - 500x

-900 = - 300x

x = -900 / -300

x = 3 hours

number of hours = 3 hours

The solution to the system of equations in this real-world context represents the number of hours both locations can be rented with the same cost.

It means both locations cost the same if rented for 3 hours each

A point (x, y) is the solution for the inequality y ≥ 2x + 1.

Radda [10]

Answer:

(0,1)

Step-by-step explanation:

We are given that a point (x,y) is the solution for the inequality

$y\geq 2x+1$

We have to find ordered pair for which y has a value that is less than or equal to and satisfies the inequality shown.

a.(3,8)

Substitute x=3 and y=8

$8\geq 2(3)+1=7$

y has a value that is not less than or equal to 1.

b.(1,1)

Substitute x=1

$y\geq 2(1)+1=3$

But given y=1 which is not greater than or equal to 3.

Therefore,y has a value that is not less than or equal to 1.

c.(2,3)

Substitute x=2

$y\geq 2(2)+1=5$

3 is not greater than or equal to 5.

It is false.

d.(0,1)

Substitute x=0

$y2(0)+1=1$

y has a value which is equal to 1.

Hence, (0,1) is true option.
