Answer:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Answer:
Rx)=1/3x^2
Step-by-step explanation:
A horizontal stretch is simply making the parabola of the parent function wider, it's kind of like changing the slope of a line to make it less steep.
In the graph, the red line is the parent function and the blue line is the horizontally stretched function. See how the blue line appears to be stretched (horizontally).
Answer:
b ≤ 50
Step-by-step explanation:
Since no more than 400 pounds of b number of 8 pound boxes can be taken off to ensure that the plane is in balance, this can be represented by the inequality:
8b ≤ 400
b ≤ 400/8
b ≤ 50
This means that a maximum number of 50 8 pounds boxes can be taken off the plane for a 600 pound crate to be put on ensuring that the plane is in balance.
Patriciana has (20/9) nickels and (80/9) dimes of coins .
<h3>Evaluation for the number of dimes and nickels.</h3>
There are 5 cents in a nickel and 10 cents in a dime.
Let the number of number of nickels be represented by the letter x, so that the number of dimes Patriciana has will be 4x.
So, 5x cents + 10 × 4x cents = 100 cents
5x cents + 40 cents = 100 cents
45x cents = 100 cents
divide through by the coefficient of x
x = 100cents/45cents
x = 20/9 by simplification,
and the number of dimes is calculated by putting 20/9 for x in 4x.
Hence, the number of dimes is 4(20/9) = 80/9 and that of nickels is 20/9.

Well first we need to find how we can turn 25 into 100
Well one way would be to multiply by 4
25 x 4 = 100
Since we multiplied the bottom number by 4 we should multiply the top number by 4.
So..
19 x 4 = 76
So our new fraction is..
76
-----
100
Now we can easily turn this into a decimal.
76/100 = 0.76
Answer = 0.76
Good Luck! :)
