Answer:

<h2>Table A represents a function.</h2>

Step-by-step explanation:

A function is a relation between two sets, which are called domain, expressed with <em>x-variable</em> and range, expressed <em>y-variable. </em>

The obligatory characteristic of a function is that every element in the domain only can have one element related in the range, that is, if we enter <em>x = 5 </em>in a function, we will just obtain one value back, like <em>y = 6, </em>in this context we cannot obtain a different value for <em>y, </em>if that happens it means that the relation is not a function.

So, in this case, Table A fulfil this definition.

Table B violate this functions definition, because <em>x = 5 </em>has to images in the range <em>y = 2 </em>and <em>y = 6</em>, both are image of a single domain value, therefore, it's not a function.

Table C and Table D do the same thing, for one domain value there's two range values.

Therefore, only Table A represents a function.

Factor 200t+83 - 80t2.<br> A. 8t(t - 5)(t + 5)<br> B. 8t(t - 5)2<br> C. -8t(t - 5)(t + 5)
Mashutka [201]

Step-by-step explanation:

8t³-80t²+200t

= 8(t³-10t+25)

= 8t(t²-10t+25)

= 8t(t-5)(t-5)

= 8t(t-5)²

the answer is B.

The price of a $250 item after successive discounts of 20% and<br> 30% is?
Ivan

Answer:

The price of item after successive discounts are 20% and 30% is $140.

Step-by-step explanation:

The marked price of item is $250.

Two successive discounts are 20% and 30%.

Price of item after discounts of 20% is

250-\frac{20}{100}(250)=250-50=200

New price of item after first discount is $200.

Price of item after second discount, i.e., 30% is

200-\frac{30}{100}(200)=200-60=140

Therefore, the price of item after successive discounts are 20% and 30% is $140.

Hoochie [10]

Answer:

C D H

Step-by-step explanation:

The best way to tackle this problem is to put each answer into the equation and evaluate the equation.

for example

-(-3.9) + 6 >= 10

3.9 + 6 >= 10

9.9 >= 10 .this is not true!

be very careful with the signs and evaluate each answer.
