Answer:An ordered pair is a set of inputs and outputs and represents a relationship between the two values. A relation is a set of inputs and outputs, and a function is a relation with one output for each input.
Step-by-step explanation:
Which of the following is the restricted value of (x-5)/(〖3x〗^2-10x-25) ? *
Given:
The expression is
[tex]\dfrac{x-5}{3x^2-10x-25}[/tex]
To find:
The restricted value of given expression.
Solution:
We have,
[tex]\dfrac{x-5}{3x^2-10x-25}[/tex]
Equate the denominate equal to 0, to find the restricted value.
[tex]3x^2-10x-25=0[/tex]
[tex]3x^2-15x+5x-25=0[/tex]
[tex]3x(x-5)+5(x-5)=0[/tex]
[tex](x-5)(3x+5)=0[/tex]
Using zero product property, we get
[tex]x-5=0\text{ and }3x+5=0[/tex]
[tex]x=5\text{ and }x=-\dfrac{5}{3}[/tex]
Therefore, the restricted values are [tex]x=5\text{ and }x=-\dfrac{5}{3}[/tex].

Answer:
Step-by-step explanation:
Given the equation y = 4 + 2x find the values for y given the value x
If x = 3 then y =
If x = -3 then y =
If x = 4 then y =
If x = -2 then y =
Answer:
If x = 3 then y = 10
If x = -3 then y = -2
If x = 4 then y = 12

which of the following pairs of functions are inverses of each other
Answer:
c would be the answer you are looking for and please mark brainliest
Step-by-step explanation:
Options A and D have functions that are inverses of each other.
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
To check whether two functions are inverses of each other, we need to check if the composition of the functions in both orders results in the input value.
Here, we need to check if f(g(x))=x and g(f(x))=x for all values of x in their domains.
A. f(x) = 7/(x-9) and g(x) = (x+9)/7
f(g(x)) = f((x+9)/7) = 7/((x+9)/7 - 9) = 7/(x/7) = x, so f and g are inverses of each other.
B. f(x) = x/6 + 8 and g(x) = 6x - 8
f(g(x)) = f(6x-8) = (6x-8)/6 + 8 = x/6 + 8/6 = x/6 + 4/3, which is not equal to x. Therefore, f and g are not inverses of each other.
C. f(x) = 2 + ∛x and g(x) = 2 - x³
f(g(x)) = f(2 - x³) = 2 + ∛(2 - x³) ≠ x, so f and g are not inverses of each other.
D. f(x) = 5x - 11 and g(x) = (x+11)/5
f(g(x)) = f((x+11)/5) = 5((x+11)/5) - 11 = x, and g(f(x)) = g(5x-11) = (5x-11+11)/5 = x/5, so f and g are inverses of each other.
Therefore, only options A and D have functions that are inverses of each other.

Reed is purchasing an X-Box One. He made an initial payment of $75 to the store, and will pay $15 each month until the system is paid off. Which equation represents the relationship between x, the number of monthly payments Reed has paid, and t, the total amount that Reed has paid the store?
A. t = 75x + 15 C. t = 15x + 75
B. t = 15x - 75 D. Not Here
C.) T=15x+75
its 15 dollars each month and since you don't know the number of months the variable would correspond with 15 and you just need to add 75 onto it
Answer:
C. t = 15x + 75
Step-by-step explanation:
since you already payed the 75 dollars you add it and you multiply 15 by x because x is the number of months you pay

Sign up cost = 0
1 Month = 125
2 Months = 150
3 Months = 175
4 Months = 200
Step-by-step explanation:
For every option simply write what the starting cost is in the top box for every option. Then multiply the monthly cost by how many months for each box and then add the starting cost. The result of the multiplication and addition will be what you put in each box.

help. please. i have to type 20 things.
Answer:
Top Left: Acute Top Right: Acute Bottom Right: Obtuse Bottom Left: Right
Step-by-step explanation:
The top left and right have all angles less than 90 degrees which makes them acute. The Bottom right has an angle over 90 degrees which makes it obtuse, and the last one has a right angle 90 degrees.
Round off 13,486 to the nearest hundred.
Answer:
13,500
Step-by-step explanation:
Answer: 13,500
Step-by-step explanation:
So the 4 is in the hundred place than u look to the right where the next digit is which is 8. If its 5 or more u round up but if its 5 or less it stays the same. So 8 is 5 or more than u round up the 4 to 5 and leave the rest of the digit 0's. but u leave the 13 the same. If that makes sense.

Step-by-step explanation:
Molly is painting her bedroom walls, and the paint costs $24 per gallon. How much does the paint cost per quart?
$3 per quart
$6 per quart
$48 per quart
$96 per quart
$6 per quart.
A quart is 1/4 of a gallon.
Answer:
$6 per quart
Step-by-step explanation:
Since we are trying to find out how much money a quart of paint will cost, we need to find out how many quarts are in one gallon.
There are 4 quarts in a gallon, therefore we take $24 divided by 4 and get $6 per quart.

The table represents some points on the graph of a linear function. What is the slope of the line?
Answer:
-9/2!
Step-by-step explanation:
For this one, It's a bit hard! But, using the process of elimination, you can tell, that since the Y's are going down, this is a negative slope. Since there was only two answers, and only one was negative, it's -9/2!
I really hope this helped... I know it wasn't the best, but I graphed it for you!
