Quadrant for for number 5

tresset_1 [31]3 years ago

5) Point D is located in Quadrant IV. Quadrant I is where x and y are both positive. Quadrant II is where x is negative and y is positive. Quadrant III is where both x and y are negative. Quadrant IV is where x is positive and y is negative.
6) Since we know that the x will be the same because it is a vertical line segment, we just have to find the absolute value of the difference between the y of the 2 points. Therefore, (3,-8) and (3,-4) is the correct answer.
7) Use the distance formula. √((y₂-y₁)²+(x₂-x₁)²). √((8-8)²+(7-(-5))²) = √(0+12²) = √12² = 12 units.

raketka [301]

Answer:

Price of a senior citizen ticket is $4 and price of a student ticket is $15 .

Step-by-step explanation:

Let us assume that the price a senior citizen ticket be x .

Let us assume that the price a student citizen ticket be y .

As given

The school that Jack goes to is selling tickets to a choral performance.

On the first day of ticket sales the school sold 9 senior citizen tickets and 8 student tickets for a total of $156.

Equtaions becomes

9x + 8y = 156

As given

The school took in $163 on the second day by selling 7 senior citizen tickets and 9 student tickets.

Equations becomes

7x + 9y = 163

Multipy 9x + 8y = 156 by 9 .

81x + 72y = 1404

Multiply 7x + 9y = 163 by 8 .

56x + 72y = 1304

Subtracted 56x + 72y = 1304 from 81x + 72y = 1404 .

81x - 56x + 72y - 72y = 1404 - 1304

25x = 100

$x = \frac{100}{25}$

x = $ 4

Putting value of x in the 56x + 72y = 1304 .

56 × 4 + 72y = 1304

224 + 72y = 1304

72y = 1304 - 224

72y = 1080

$y = \frac{1080}{72}$

y = $15

Therefore the price of a senior citizen ticket is $4 and price of a student ticket is $15 .
