Answer:
Yes
Step-by-step explanation:
The domain is {-19, 19}
The range is {0,16}
We can write as ordered pairs to obtain:
(-19,0), (19,16)
None of the first coordinates of the ordered pairs repeats.
Hence the relation represents a function.

Step-by-step explanation:
Hello!
The variable of interest is
X: air pressures of properly inflated sports balls.
<em>Average recommended psi Tolerance
</em>
<em>(pounds per square inch)
</em>
<em>Soccer ball 12.05
±3.55
</em>
<em>Basketball 8.00
±0.5 </em>
<em>Volleyball 4.44
±0.18</em>
Each recommendation is expressed like the "average air pressure" ± "standard deviation of the recommended air pressure" so if you express it in inequality it will be:
X[bar]-S ≤ X ≤ X[bar]+S
So for each ball type, you can write it as:
<u>Soccer ball</u>
12.05-3.55 ≤ X ≤ 12.05+3.55
8.5 ≤ X ≤ 15.6
<u>Basketball</u>
8.00-0.5 ≤ X ≤ 8.00+0.5
7.5 ≤ X ≤ 8.5
<u>Volleyball</u>
4.44-0.18 ≤ X ≤ 4.44+0.18
4.26 ≤ X ≤ 4.62
I hope this helps!
Answer:
18 is divisible by both 2 and 9, you can multiply 9 by 2 to get 18, and 18 is a multiple of both of those numbers

Answer:
0.06
Step-by-step explanation:
0.42 ounces is enough for 14 plants. After watering 12 plants, there will be enough plant food left over for 2 plants. Write a proportion:
0.42 / 14 = x / 2
Cross multiply:
14x = 0.84
Solve:
x = 0.06
