If the width of a rectangle is 9 ft less then twice it’s length and the perimeter is 30 feet, what are the dimensions of the rectangle?
The dimension of the rectangle is,
The length of the rectangle is 7 feet.
And the width of the rectangle is 8 feet.
Given that,
If the width of a rectangle is 9 ft less than twice its length and the perimeter is 30 feet,
We have to determine,
What are the dimensions of the rectangle?
According to the question,
Let, the width of the rectangle is W,
And the length of a rectangle is L = 2W - 9,
The perimeter of the rectangle is = 2(L+W)
Where perimeter is 30 feet,
Therefore,
[tex]30 = 2(2W-9+W)\\\\30 = 2(3W-9)\\\\30 = 6W-18\\\\30 + 18 = 12W\\\\48 = 6W\\\\W = \dfrac{48}{6}\\\\W = 8 \ feet[/tex]
And the length of a rectangle is,
[tex]L = 2W - 9, \\\\L= 2(8) - 9\\\\L = 16-9 \\\\L =7 \ feet.[/tex]
Hence, The dimension of the rectangle is, the length of the rectangle is 7 feet, and the width of the rectangle is 8 feet.

The Gonzalez's updated their bedroom by purchasing a new lamp for $89.95 and a comforter set for $239.99. They paid 6.5% sales tax on their purchases. If the Gonzalez's paid $351.72 total, determine if they paid the correct amount.
Answer:
Not exactly
Step-by-step explanation:
Cost lamp = $89.95Cost of comforter set = $239.99Sales tax = 6.5%Total payment:
($89.95 + $239.99)*1.065 = $351.39Total amount is a little different:

Answer:
x=-24
Step-by-step explanation:
Answer:
It is -24.
Step-by-step explanation:
First distribute 2/3 on the left side, and distribute 1/2 on the other side. Now you have 1 /3 x + 8 = 1/ 6 x + 7 + (−3). Now, combine like terms. Now you should have 1 /3 x + 8 = 1 /6 x + 4. Now, subtract 1/6x on both sides. You should now have 1 /6 x + 8 = 4. Subtract 8 from both sides, and you should have 1/6x = -4. Now the last step is to multiply by 6 on both sides. Now you should get -24. Have a good day!

Sindhu’s present age is thrice of Shilpa. If Shilpa’s age three years ago was x, then Sindhu’s present age is
3 (x – 3)
3x + 3
3x – 9
3(x + 3)
Answer:
I think "D"- 3(x + 3)
Step-by-step explanation:
as 3 years ago - x
so present age of shilpa - x +3
~~~~~~~~~~~~~
present age of sindhu - 3 (x+3)
i guess : )
Shilpa's age three years ago
Shilpa's age now = x + 3
Sindhu's age now = 3(x + 3)
What is the value of g(-9) for the function g(x) = x2 - x?
Answer:
72Step-by-step explanation:
Given the function;
g(x) = x^2 - x
We are to find g(-9)
g(-9) = (-9)² - 9
g(-9) = 81 - 9
g(-9) = 72
hence the value of g(-9) is 72

Write an equation in Slope intercept form of the line that passes through the given points (-3,4) (1,4)
The equation for the line that passes through the point A ( -3 , 4 ) and
B ( 1 , 4 ) is y = 4
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the first point be A ( x₁ , y₁ ) = A ( -3 , 4 )
Let the second point be B ( x₂ , y₂ ) = B ( 1 , 4 )
Now ,
The equation for the line is given by
y - y₁ = m ( x - x₁ )
To find the slope of the line ,
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values , we get
m = ( 4 - 4 ) / 1 - ( - 3 )
m = 0
So , the slope of the line is 0
Now ,
The equation of line will be
y - 4 = 0 ( x - ( -3 ) )
y - 4 = 0
Adding 4 on both sides , we get
y = 4
So , the equation of the line is y = 4

-1/2
1/2
Answer:
-2
Step-by-step explanation:
first, you want to graph your points on a graph. A really good online graphing calculator i like is called desmos.
next, slope is rise over run. count how many units up or down from leftmost point to the other. in this case it is -8.
third, find the run part of the slope by counting units right or left from the leftmost point to the other. in this case it is 4.
last, but the two numbers together in a fraction and simplify. rise over run.
-8/4 which simplifies to -2/1 which is the same thing as -2
