There is one solution, (0,4) is your answer

Note that x = 0, y = 4

(4) = 1/3(0) + 4

4 = 0 + 4

4 = 4 (true)

3(4) - (0) = 12

12 - 0 = 12

12 = 12 (true)

Uni made a model of a 1970 Ford Mustang using a scale of .5 inches = 9 in. If the actual car is 15 ft long, how long is the mode

kykrilka [37]

Answer:

The model car is 10 inches long

Step-by-step explanation:

To solve this question, we use conversion of units

Feet to inches.

Each feet has 12 inches.

The car is 15ft long.

So the car has 15*12 = 180 inches.

.5 inches = 9 in.

Rule of three

.5 inches - 9 inches

x inches - 180 inches

$9x = 180*0.5$

$9x = 90$

$x = \frac{90}{9}$

$x = 10$

The model car is 10 inches long
