15(15b−7)=3b−9 plz help meee
Answer:
B=16over37
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
15(15b−7)=3b−9
(15)(15b)+(15)(−7)=3b+−9(Distribute)
225b+−105=3b+−9
225b−105=3b−9
Step 2: Subtract 3b from both sides.
225b−105−3b=3b−9−3b
222b−105=−9
Step 3: Add 105 to both sides.
222b−105+105=−9+105
222b=96
Step 4: Divide both sides by 222.
222b
222
=
96
222
Then simplify
Answer:
Step-by-step explanation:
15(15b-7)=3b-9
225b-105=3b-9
+105 +105
225b=3b+96
/3 /3
75b=b+96

A. The relation {(−1, 1), (0, 2), (3, −2), (5, 2)} is not a function, but the relation has a domain of {−1, 0, 3, 5} and a range of {1, 2, −2}.
B. The relation {−1, 0, 3, 5} is not a function and has no domain or range.
C. The relation {(0, 1), (0, 2), (0, 3), (0, 4)} is not a function, but the relation has a domain of {1, 2, 3, 4} and a range of {0}.

Pina filled out the following information on the back of her monthly statement:
Ending balance from statement $1,139.78
Deposits outstanding
+ $280.67
Total of checks outstanding
- $656.91
Revised statement balance
Balance from checkbook
$763.54
Find Pina's revised statement balance. Does her account reconcile?
Answer:
yes
Step-by-step explanation:
It is true that Pina's account reconciles.
The monthly statement is given as:
Ending balance from statement $1,139.78 Deposits outstanding + $280.67 Total of checks outstanding - $656.91 Revised statement balance $ Balance from checkbook $763.54Start by calculating the revised statement at the end of the month.
This is calculated using:
[tex]Revised = Ending\ Balance + Deposit\ Outstanding - Checks\ Outstanding[/tex]
So, we have:
[tex]Revised = \$1139.78 + \$280.67 - \$656.91[/tex]
Evaluate the expression
[tex]Revised = \$763.54[/tex]
By comparison, the revised statement equals the balance from the checkbook.
Hence, we can conclude that her account reconciles.

Which relation is a function?
{(1, 2); (2, 3); (3, 4); (1, 5)}
{(1, 2); (1, 3); (3, 2); (4, 2)}
{(1, 2); (2, 5); (3, 2); (4, 5)}
{(1, 2); (2, 3); (3, 4); (2, 5)}
Answer:
the third relation: {(1, 2); (2, 5); (3, 2); (4, 5)}
Step-by-step explanation:
relations can only be a function if the input/x don't repeat at all.
its ok if the output/y repeat though!
{(1, 2); (2, 5); (3, 2); (4, 5)}, best represents the functions. Option C is correct.
Given that,
To determine which relation is a function.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Here,
For a relation to be a function, for two variables only one of the variables can have a repeated value i.e. dependent variable with respect to the others if the value of both variables is repeating then the relation is not a function. So,
{(1, 2); (2, 3); (3, 4); (1, 5)}
X repeated twice its not the function.
Similarly,
{(1, 2); (2, 3); (3, 4); (2, 5)} and {(1, 2); (1, 3); (3, 2); (4, 2)} are not the function.
But,
{(1, 2); (2, 5); (3, 2); (4, 5)} is function because the value of independent variable is not repeating.
Thus, {(1, 2); (2, 5); (3, 2); (4, 5)}, best represents the functions. Option C is correct.

the log ride at an amusement park has a single hill with an incline of 127 feet and a decline of 93 feet. If the total horizontal distance between the start of the incline and end of the decline is 132 feet, find the maximum height of the ride
Answer:
85.02 feet
Step-by-step explanation:
In order to solve this we need to use Herons formula to discover the Area of the triangle and then solving the formula of the area to find the height.
Herons formula starts by calculating the semi-perimeter which is half the perimeter of the Triangle:
[tex]s=\frac{a+b+c}{2}\\ s=\frac{127+93+132}{2}\\s=176[/tex]
Now that we knwo that s= 176 we need to use the second part of the formula:
[tex]A=\sqrt{(S-A)(S-B)(S-C)} \\\\A=\sqrt{(176-127)(176-93)(176-132)}\\A=\sqrt{176(49)(83)(44)} \\A=5612.02[/tex]
So the area is 5612.02, with that we just have to solve the equation for area, which is [tex]A=\frac{B*H}{2}[/tex]
So it would be 2A*B=H
H=2*5612.02*132
H=85.03

What's a better show, Trailer Park Boys or Adventure Time?
Answer:
adventure time 100%
Step-by-step explanation:
Both are the best shown in their place.
Trailer Park Boys:A mockumentary sitcom television series from Canada called Trailer Park Boys was created by Mike Clattenburg. The television series, which is a continuation of Clattenburg's 1999 movie of the same name, chronicles the misadventures of a group of trailer park residents, some of whom are ex-convicts, who reside in the fictitious Sunnyvale Trailer Park in Dartmouth, Nova Scotia. After making its Showcase debut on April 22, 2001, the program initially aired for seven seasons before coming to an end with an hour-long special on December 7, 2008. Three additional movies based on the TV show have been produced: The Movie (October 6, 2006); Countdown to Liquor Day (September 25, 2009); and Don't Legalize It (April 18, 2014).Adventure Time:Pendleton Ward produced the American fantasy animated television series Adventure Time[c] for Cartoon Network. The show centers on the exploits of Finn (Jeremy Shada), a young kid, and Jake (John DiMaggio), a dog with the magical ability to change size and shape at will. They engage with Princess Bubblegum (Hynden Walch), the Ice King (Tom Kenny), Marceline (Olivia Olson), BMO (Niki Yang), and other characters while living in the post-apocalyptic Land of Ooo.
Therefore, there is no comparison between the shows, both are the best shows in their place.

You take a package to the local shipping company. They charge $0.72 per pound, and also has a fixed cost of $5
per package. If P represents the number of pounds of your package, and C is the total cost of shipping your
package, which of these is the correct relationship between P and C?
Answer:
yoy didnt put a picture of the answer choices, so I'm not sure which one this would be, but the answer would be C=5 + .72P
Step-by-step explanation:
C is the total cost, so that would be on the opposite side of the equal sign from P. the 5 would be the constant, since that is the starting price for all packages, and the .72 is the price per pound, so you would have to multiply .72 by P pounds in order to complete the equation.

Enter decimal numbers in the boxes to identify the point in Quadrant III which is 3 units away from point A.
Answer:
(-0.5, -0.5)
Step-by-step explanation:
Let the coordinates of the point P in quadrant 3 are (x, y).
If a point A is 3 units apart, coordinates of point P will be [(x - 3), y].
From the figure attached,
Coordinates of the point A are (2.5, -0.5).
x coordinate of point P → (2.5 - 3) = -0.5
y coordinate of the point P → (-0.5) = -0.5
Therefore, point P which is 3 units apart from A will be (-0.5, -0.5)
