D: All real numbers except x=-1 and x=1
Step-by-step explanation:
Step-by-step explanation:
The domain of the rational expression is when the denominator is defined. (non-zero)
When the denominator is 0,
4x² - 4 = 0.
=> x² - 1 = 0, (x + 1)(x - 1) = 0, x = -1 or x = 1.
Hence the answer is all real numbers except x = -1 and x = 1.

Step-by-step explanation:
4(5x+2)=14x+32
20x+8 = 14x+32
20x-14x+8=14x-14x +32 (Both side +14x)
6x+8=32 (cancel 14x -14x)
6x+8-8=32 -8(both side -8)
6x=24 (both side divide 6)
6x/6=24/6

The factors of a given cubic polynomial function are
( x-1) (x -2 ) and (x +3)
Step-by-step explanation:
Step(i):-
Given that x³ - 7x + 6=0
f(x) = x³ - 7x + 6=0
put x=1
f(1) = 1 -7 +6 =0
(x -1 ) is one factor of given polynomial
By using synthetic division
x³ x² x constant
x=1 ║ 1 0 -7 6
║ 0 1 1 -6
1 1 -6 0
The polynomial ( x² + x - 6) =0
Step(ii):-
The factors of
x² + x - 6=0
x² + 3x -2x - 6=0
x ( x +3 ) - 2( x +3) =0
(x -2 ) ( x+3 ) =0
x = 2 and x =-3
Final answer:-
The factors of a given cubic polynomial function are
( x-1) (x -2 ) and (x +3)

Answers
Given :
A crafter is making a triangular flag.
She has two sides of length 24 inches and 36 inches.
To Find :
The length possibilities (in whole inches) for the third side.
Solution :
We know, the sum of two sides of any triangle is always greater than the length of the third side.
Let, third side is d.
So, d is always less than the sum of other sides i.e. ( 24 + 36 ) = 60 .
d < 60
Also, difference between the difference of length is always less than the side.
So, d > 36 - 24
d > 12
Therefore, the length possibilities for the third side is between 13 inches and 59 inches.

Which inequality is shown in this graph? (0, 2) (-1,-2)
A. y2-4x+ 2
B. yz 4x + 2
C. ys - 4x + 2
D. y = 4x+2
Answers
Answer:
D) y = 4x + 2
Step-by-step explanation:
Explanation:-
Given ( 0, 2) ( -1 , -2 )
Given in equalities y = 4x + 2
put point (0,2) in equation y = 4x +2
2 = 4(0) +2
2 = 2
Therefore satisfies the point (0,2) equation y = 4x +2
put point (-1,-2) in equation y = 4x +2
-2 = 4(-1)+2
-2 = -2
Therefore satisfies the point (-1,-2) equation y = 4x +2

with a circle drawn on the map. The center of the lake is 19 miles east and 3 miles south of the town hall, and the
radius of the lake is 0.5 miles.
If the positive x-axis represents east and the positive y-axis represents north, which equation represents the lake?
O (x + 19)2 + (y - 3)2 = 0.5
O (x – 19)2 + (y + 3)2 = 0.5
O (x + 19)2 + y - 3)2 = 0.25
O (x - 19)2 + ( + 3)2 = 0.25

The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
The equation for a circle is given as:
(x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle and r is the radius.
The center of the lake is 19 miles east and 3 miles south, i.e. (-19, -3) and the radius is 0.5 miles.
The equation of the lake is:
(x - (-19))² + (y - (-3))² = 0.5²
(x + 19)² + (y + 3)² = 0.25
The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25

Answer: D. [tex](x-19)^2+(y+3)^2=0.25[/tex]
Step-by-step explanation:
Let's review what we know:
the lake is circularthe town hall is at the originthe center of the lake is 19 miles east of the origin and3 miles south of itthe radius of the lake is 0.5 milesA circle can be depicted on the coordinate plane with the equation [tex](x-h)^2+(y-k)=r^2[/tex], where:
(h, k) is the center of the circleand r is the radius of the circle19 miles east of the origin would be 19 units to the right of the origin on the coordinate plane, as east is the rightwards direction in real life. In short, h = 19.
Let's plug in that value: [tex](x-(19))^2+(y-k)^2=r^2[/tex].
So we know that the x-coordinate defining part of the equation would have to be [tex](x-19)^2[/tex].
Meanwhile, 3 miles south of the origin would be modeled as three units underneath it, because south would be considered "downwards". The y-value (k) would be negative 3.
Putting what we have so far together, the center of the circle would be (19, -3).
Therefore, the y-coordinate defining part of the equation would be [tex](y+3)^2[/tex].
Here's what the equation looks like with the work we've completed so far: [tex](x-19)^2+(y+3)^2=r^2[/tex]
Finally, let's plug in the radius value 0.5.
0.5 * 0.5 = 0.25
Ailani would use the equation [tex](x-19)^2+(y+3)^2=0.25[/tex] to model the lake in relation to the town hall. I hope that makes sense!
