9 and 8 are the two numbers.
9 + 8 = 17
9 - 8 = 1
Answer:
Step-by-step explanation:first you have to go Wrexham
Mold to Wrexham is 12 mile one way. From Wrexham
to Oswestry is 15 mile oneway.
12 + 15 = 27 mile oneway from Mold to Oswestry
roung trip 54 miles a day
54 x 5 = 270 miles
The drain rate is constant and thus equal to the average drain rate over the entire 4.5 hour period. This rate is
![\dfrac{0 \,\mathrm L - 180 \,\mathrm L}{4.5 \,\rm h} = -40 \dfrac{\rm L}{\rm h}](https://tex.z-dn.net/?f=%5Cdfrac%7B0%20%5C%2C%5Cmathrm%20L%20-%20180%20%5C%2C%5Cmathrm%20L%7D%7B4.5%20%5C%2C%5Crm%20h%7D%20%3D%20-40%20%5Cdfrac%7B%5Crm%20L%7D%7B%5Crm%20h%7D)
which is to say, water flows <u><em>from</em></u> the tank at a rate of 40 L/h.
Answer:
- 7
- see below
- 5
- the rule is not one-to-one
Step-by-step explanation:
Applying the squaring rule to each of the elements of the domain, we get ...
![\begin{array}{cc}\text{Domain}&\text{Range}\\1&1\\-3&9\\-\frac{1}{2}&\frac{1}{4}\\3&9\\2&4\\\frac{1}{4}&\frac{1}{16}\\0.5&\frac{1}{4}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D%5Ctext%7BDomain%7D%26%5Ctext%7BRange%7D%5C%5C1%261%5C%5C-3%269%5C%5C-%5Cfrac%7B1%7D%7B2%7D%26%5Cfrac%7B1%7D%7B4%7D%5C%5C3%269%5C%5C2%264%5C%5C%5Cfrac%7B1%7D%7B4%7D%26%5Cfrac%7B1%7D%7B16%7D%5C%5C0.5%26%5Cfrac%7B1%7D%7B4%7D%5Cend%7Barray%7D)

1. There are 7 different numbers in the Domain list.
2. See above
3. There are 5 different numbers in the Range list.
4. The rule "square me" is not "one-to-one" Two different values in the domain can result in the same value in the range. -3 and 3 both result in 9. -1/2 and 0.5 both result in 1/4.
