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.
Answer:
x = 74
Step-by-step explanation:
2 * x + 19 = 167
2x + 19 = 167
So we have to subtract 19 from both sides
2x = 148
Divide both sides by 2
x = 74
12a.
35 + 3c = 45 + 2c subtract 35 from both sides
3c = 10 +2c subtract 2c from both sides
c = 10
A 10 minute phone call would cost the same amount of money with both companies.
12b.
It is better to use Company B when you need to make a longer phone call because the cost per minute is less. For example, an hour long phone call with company A would be $2.15 and the same call with company B would be $1.95.
14.
The problem with Delia's work is that she put the x with the flat rate instead of the daily charge. The flat rate will only be charged once while the daily fee should be multiplied and charged for every day, x. The correct equation would have been 365 + 125x = 250 + 175x.
