Answer:

Let f be a function. If any horizontal line intersects the graph of f more than once, then f does not have an inverse. An absolute value function (without domain restriction) has an inverse that is NOT a function. That's why an absolute value function does not have an inverse function。

The ratio of money in Terry's bank account to Faye's bank account was 3:7. Terry then put £220 in his account and Faye withdrew

Nesterboy [21]

Answer:

£910

Step-by-step explanation:

let 3x and 7x be the initial amounts in their accounts, then after alterations

Terry has 3x + 220

Faye has 7x - 300

After these changes the amounts are equal, hence

7x - 300 = 3x + 220 ( subtract 3x from both sides )

4x - 300 = 220 ( add 300 to both sides )

4x = 520 ( divide both sides by 4 )

x = 130

Faye initially had 7 × £130 = £910 in her account

Answer:

B. Graph of a one-to-one function.

Step-by-step explanation:

A one-to-one function will have a unique value, y, for each different value of x. The graph displayed will have values very, very close to each other as x approaches ±4, but they won't be the same even at higher values of x.

How can I use number patterns to find the lcm of 120 and 360

SashulF [63]

You can use number patterns to find the LCM of 120 and 360 by multiplying 120 by 1,2,3,4,5,6,and so on and do the same with 360 until you find the least number that they have in common.

The directions on a bottle of vinegar say mix 1 cup of vinegar with 1 gallon of water to make a cleaning solution the ratio of v

ale4655 [162]

Answer:

Step-by-step explanation:

"mix one cup of vinegar with one gallon of water"

1 cup = 8oz; one/4 cup = 2oz

You can see that quantity|the quantity|the number} of vinegar is 1/4 of the first amount,

so, we are going to would like 1/4 of the number of water, that is 1gallon = 128oz

so, 1/4 times 128oz = 32oz, that is one quart

Algebraically, 8oz : 128oz = 2oz : x

8x = 256; x = 32oz
