Linear is y=my+b but sequence arithmetic is t(x)=dn+t(0)

2x + 12 = 58 <== ur equation (cost of the trip)

2x = 58 - 12

2x = 46

x = 46/2

x = 23 <== price of 1 pass

5x + 4y ≤ 20

5x - 5x + 4y ≤ 20 - 5x

<u>4y</u> ≤ <u>20 - 5x</u>

4 4

y ≤ 5 - 1.25x

**Answer:**

x = 5 and y = 13

**Step-by-step explanation:**

<u>Points to remember</u>

The ratio of of corresponding sides of similar triangles are equal.

From the figure we can see two similar triangle

**<u>To find the value of x</u>**

x/(x + 15) = 12/48

x/(x + 15) = 1/4

4 * x = x + 15

4x - x = 15

3x = 15

x = 15/3 = 5

**<u>To find the value of y</u>**

y/(y + 39) = 12/48 = 1/4

4y = y + 39

3y = 39

y = 39/3 = 13

Therefore x = 5 and y = 13

**Answer:**

**<u>120</u>**

**Step-by-step explanation:**

15 ⋅ 8 = 120
