Answer:

Step-by-step explanation:

Note that the four input values, {3,4,6,11}, are all unique. Each has exactly one y value associated with it. This is an important criterion when we're deciding whether a relation is a function or not.

Suppose that we added one more input and its associated output:

{3,4,4,6,11}

If it happened that different values of y were associated with the two 4's, then we know immediatel that this relation is not a function.

Answer:

x² + 8

Step-by-step explanation:

note (f - g)(x)

= f(x) - g(x)

= 2x² + 1 - (x² - 7) = 2x² + 1 - x² + 7 = x² + 8

Identify and solve the inequality that represents how many $20 bills, n, you can withdraw from the account without going below t

Alex Ar [27]

Answer:

$100 + 20n \leq 230$

$n \leq 6$

Step-by-step explanation:

Given

$Balance = \$230.00$

$Minimum = \$100$

$Withdrawal = \$20\ each$

Required

Represent using an inequality and solve

Let the number of dollars be represented by n

<em>If 1 withdrawal is $20 bill</em>

<em>n withdrawals would be $20n bills</em>

The total withdrawal and the minimum balance must be less than or equal to the available balance.

So, this gives

$Minimum + Total\ Withdrawal \leq Available\ Balance$

Substitute values for each of these

$100 + 20n \leq 230$

Solving for n

$20n \leq 230 - 100$

$20n \leq 130$

Divide through by 20

$n \leq 6.5$

But n can not be decimal because it represents number of dollar bills , which must always be an integer.

So, we round down the value of n

$n \leq 6$

Write an expression that represents the total owed for 6 months of cable at a price of c dollars for each month, plus a one-time

matrenka [14]

Answer is 6(c) + 50

Step by step

We know the following

6 months cable multiplied by “c” dollars per month plus $50 one time fee
6 (c) + $50

We multiply 6 months times the unknown “c” per month. Then we add the one time fee.

The other three options multiply $50 by 6 months, by 2 and by “c”, therefore not correct.
