Answer:
17
Just substitution!
Step-by-step explanation:
f(-2) = 17×(3-2)
Applying the rules, it is found that ordered pair (24,6), option A, works for both rules.
---------------------
The rule 1 is that y is x divided by 4, that is:
![y_1 = \frac{x}{4}](https://tex.z-dn.net/?f=y_1%20%3D%20%5Cfrac%7Bx%7D%7B4%7D)
The rule 2 is that y is x subtracted from 18, that is:
![y_2 = x - 18](https://tex.z-dn.net/?f=y_2%20%3D%20x%20-%2018)
In item A, we have that the input x = 24, thus, the results of the expressions are:
![y_1 = \frac{24}{4} = 6](https://tex.z-dn.net/?f=y_1%20%3D%20%5Cfrac%7B24%7D%7B4%7D%20%3D%206)
![y_2 = 24 - 18 = 6](https://tex.z-dn.net/?f=y_2%20%3D%2024%20-%2018%20%3D%206)
In both cases, ordered pair (24,6), thus <u>option A is the answer.</u>

Answer:
y = 8x - 11
Step-by-step explanation:
Using the equation
<u>y - y1 = m (x - x1)</u>
<u>y - 5 = 8 (x- 2)</u>
<u>y - 5 = 8x - 16</u>
Subtract the 5
y = 8x - 11
Perimeter is found by simply adding all sides together. A parallelogram has only 4 sides, 2 of them are one measurement, the other 2 are another measurement.
Meaning, you can simply take 7*2 +11*2 and you have an answer.
7*2=14
11*2=22
22+14=36
The perimeter is equal to 36 inches
One inch equals 8 miles, or in math terms, this is how we figure It out...
![24m = 3in](https://tex.z-dn.net/?f=24m%20%3D%203in)
To find the scale we need to find what one inch equals on the map, dmto do this we divide both sides by 3 in. and get 8 miles in reality equals one map inch.
