Step-by-step explanation:
From the image given, we can tell that there are two sides for angle H for the segment IJ. From that we can see that angle H is a supplementary angle. A supplementary angle is an angle whose sum is 180°So: (2m+10)°+(5m+100)° = 180°(7m+110)° = 180°(7m)° = 70m = 10Tommy’s bedroom is in the shape of a square.

make y the subject of the formula x=a-2by squared
Answers
Answer:
y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]
Step-by-step explanation:
Given
x = a - 2by² ( subtract a from both sides )
x - a = - 2by² ( multiply through by - 1 to clear the leading negative )
a - x = 2by² ( divide both sides by 2b )
[tex]\frac{a-x}{2b}[/tex] = y² ( take the square root of both sides )
y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]
Making y the subject of the formula, [tex]x = a - 2by^2[/tex] , the answer would be:
[tex]\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]
Given the formula: [tex]x = a - 2by^2[/tex],
Required:
Making y the subject of the formula
This is done as shown below:
[tex]x = a - 2by^2[/tex]
Subtract a from both sides[tex]x - a = - 2by^2[/tex]
Divide both sides by -2b[tex]\frac{x - a}{-2b} = y^2[/tex]
Take the square root of both sides[tex]\sqrt{\frac{x - a}{-2b}} = y\\\\\\\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]
Therefore, making y the subject of the formula, [tex]x = a - 2by^2[/tex] , the answer would be: [tex]\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]

There is a rectangular pool and small border. The pool and boarder measures x+3 by x-2. The pool alone measures x+2 by x+1. what is the area of the boarder
Answers
Answer:
-2x -8
Step-by-step explanation:
The border area will be the difference between pool+border and pool. The area of each rectangle is the product of its dimensions.
(x+3)(x-2) -(x+2)(x+1) = (x^2 +x -6) -(x^2 +3x +2)
= x^2(1 -1) +x(1 -3) +(-6 -2)
= -2x -8 . . . area of border

Use elimination to solve the system of equations. 2x+y=4 and -4x-2y=8
Answers
Answer: No solution
Step-by-step explanation:
To use elimination method, we need to choose a variable to eliminate. Let's eliminate x. To eliminate x, the x coefficient in both equations must be the same, regardless of the sign. To do so, let's multiply the first equation by 2.
(2x+y=4)2
-4x-2y=8
-------------------------------------------------------------------------------------------------------------
4x+2y=8
-4x-2y=8
Let's add both equations together.
0=8
-------------------------------------------------------------------------------------------------------------
Now that we got this far, we can see that something is wrong. This normally doesn't happen. If you notice, the second equation is the first equation but multiplied by 2. Instead, let's rewrite each equation.
2x+y=4 [subtract both sides by 2x]
y=-2x+4
-4x-2y=8 [add both sides by 4x]
-2y=4x+8 [divide both sides by -2]
y=-2x-4
-------------------------------------------------------------------------------------------------------------
If you analyze both equations, you will see that they are parallel lines. We know this because the slopes are the same, but different y-intercept. from our knowledge of parallel lines, they NEVER touch or cross. This means there would be no solution at all.
