Answer:
The length of the rectangle is 15 inches and the width is 33 inches
Step-by-step explanation:
The dimensions for the rectangle are as follows:
L=L and W=2L+3
The equation for perimeter of a rectangle is:
P=2l+2w
To Solve:
1. Plug values into perimeter equation
96=2(L)+2(2L+3)
2. Simplify the equation above.
96=2L+4L+6
3. Combine like terms:
96=6L+6
4. Solve for L by subtracting 6 from both sides:
90=6L
5. Solve for L by dividing both sides by 6:
15=L.
6. Plug 15 into the equation for the width:
2(15)+3=w
30+3=w.
The mean of 20 observations is 12.5. By error, one observation was noted as (-15) instead of 15. Then the correct mean is ___?
Answer:
The correct mean is -12.5.
Step by step explanation:
If one of the 20 observations is a negative number, then the mean would be negative. This is because, when a negative number is in contact with (meaning added, subtracted, multiplied by) a positive number, the whole answer is negative, because it's opposite signs.

What is the coefficient of x 8+5x-y
Answer:
The coefficient is 5.
Step-by-step explanation:
The coefficient is the number that comes before the variable, 8 wouldn't be a coefficient because it doesn't have a variable, so therefore the correct answer is 5.
I hope I could help :)
The solution is 5
The coefficient of the equation A = 8 + 5x - y is 5
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
The value of A is
A = 8 + 5x - y be equation (1)
Let the coefficient be = c
The coefficients are the numbers by which the variables in an equation are multiplied
So , the coefficients of the equation is 5
Therefore , the value of c = 5
Hence , the coefficient of the equation is 5

Answer: 44.5
Hope this helps :)
In an isosceles triangle, the measure of a base angle is (2x+5)° . At the vertex the measure of an exterior angle is (5x-3)°
There will be an extention at the vertex
Answer:51.14
Step-by-step explanation:since its an isosceles triangle all interior angles are gonna be equal the exterior angle plus interior angle is will be kept equal to 360
2x+5+5x-3=360
7x+2=360
7x=358
x=51.14
The measure of each angle is 31, 31 and vertex angle is 118.
What is Exterior angle Property?If a triangle side is created, the outside angle that results is equal to the product of the two opposite internal angles.
Given:
Base angle = (2x+ 5) and Vertex = (5x- 3)
So, We know that the exterior angle is equal to sum of opposite interior angle
5x- 3 = 2x+ 5 + 2x + 5
5x - 3= 4x + 10
x= 13
Thus, Each angle measure 2(13)+ 5 = 31 and
third angle = 180 - (5x- 3) = 180- 62 = 118
Hence, the measure of each angle is 31, 31 and vertex angle is 118.

Answer
A y = 3x + 2
B 3y - I= -21
Cy- 2 = {(x + 1)
Dy - 3x = -7
Answer:
Choice C
Step-by-step explanation:
First when we are looking for a system of equations that has no solution we are looking for two lines that won't intersect and the only lines that would never intersect are parallel lines.
Ok so what we are looking for is an equation with the same slope but different y-intercept. A parallel line should go at the same rate like the other line but shouldn't start at the same point.
[tex]y=\frac{1}{3}x-7[/tex]
Analysing Choice A:
[tex]y=3x+2[/tex]
We just said that the slope has to be the same so this one can't be it.
Analysing Choice B:
For this one we have to put it in slope-intercept-form.
[tex]3y-x=-21\\3y=x-21\\y=\frac{1}{3}-7[/tex]
So we see that the slope is the same for this one and and the y-intercept is also the same which is NOT what we need so on tho the next one.
Analysing Choice C:
For this one we also have to put it in slope-intercept-form.
[tex]y-2=\frac{1}{3}(x+1)\\y-2=\frac{1}{3}x+1\frac{1}{3}\\y=\frac{1}{3}x-\frac{2}{3}[/tex]
We see that the slope are the same and the y-intercept are different so this is the one we are looking for.
Sorry but for the sake of time I won't analyze choice D.
Please help!!! thank you!!! *will give brainliest*
Answer: Choice C
[tex]y = x^2+2, \ x \ge 0[/tex]
=============================================
Work Shown:
[tex]f(x) = \sqrt{x-2}\\\\y = \sqrt{x-2}\\\\x = \sqrt{y-2} \ \text{ swap x and y}\\\\x^2 = y-2 \ \text{ square both sides}\\\\y = x^2+2\\\\f^{-1}(x) = x^2+2\\\\[/tex]
Since the range of f(x) is [tex]y \ge 0[/tex] this means the domain of the inverse will be [tex]x \ge 0[/tex]
The domain and range swap when you go from the original function to the inverse, or vice versa (due to x and y swapping)
So we must state the inverse is [tex]y = x^2+2 , \ x \ge 0[/tex]
