Help pls. Solve the system of linear equations by substitution.

Mathematics
1 answer:
Gekata [30.6K]3 years ago
3 0

Answer:

(5, 3)

Step-by-step explanation:

x = 17 - 4y \\ y = x - 2

Substitute x into y:

y = (17 - 4y) - 2 \\ y = 15 - 4y \\ y + 4y = 15 \\ 5y = 15 \\ y = 3

Substitute y into x:

y = x - 2 \\ 3 = x - 2 \\ 3 + 2 = x \\ x = 5

Therefore your answer is (5, 3).

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

What is the measure of Arc BA? An explanation would be much appreciated.
yKpoI14uk [10]

Answer:

m<BA = 180degrees

Step-by-step explanation:

First you must know that measure of <BA is 180 degrees and m<CD = m<BA

Since <CD = 16z - 12, hence;

180 = 16z - 12

16z = 180++12

16z = 192

z = 192/16

z = 12

Get <BA

m<BA = 16z - 12

m<BA = 16(12) - 12

m<BA = 192 - 12

m<BA = 180degrees
