What is the slope of the line through (-9, 6) (-3, 9)
Which expression is equivalent to x2 + 2x + 2
a. (x + 1 - i ) (x + 1 + i)
b. (x - 1 + i) (x - 1 - i)
c. (x + 1 - i ) (x + 1 - i)
d. ( x + 2) (x + 1)
The answer is Option A.
x + 1 - i ) (x + 1 + i)
Solution:
x (x+2) +2
(x+1)² + 1
= (x + 1 - i ) (x + 1 + i)
Answer:
Step-by-step explanation:
for the expression you wrote: x2 + 2x + 2 the answer is: none
the expression you have there is: x² + 2x + 2 and the answer is: a
by expanding a:
(x + 1 - i ) (x + 1 + i) = x² + x + xi + x + 1 + i - xi - i + 1
(x + 1 - i ) (x + 1 + i) = x² + x + x + 1 + 1
(x + 1 - i ) (x + 1 + i) = x² + 2x + 2
Simplify and then evaluate the equation
when a = 2 and b = 4.
b2 + 3(b-b2) – 2a = [?]
Help please
solve the equation
-3|3x+6|+2=9
Answer:
x= -0.36
firstly you need to open the brackets
-3(3x +6) + 2=9
-9x -18 + 2=9
secondly join the like terms together
-9x = 9 + 18 - 2
-9x = 25
thirdly you divide both sides by 25
-9x ÷ 25 = -0.36
x= -0.36

Answer:
b = -6.307 or -11.693
Step-by-step explanation:
[tex]b^{2} +9b +13\\[/tex]
This can't be factored so you need to use the quadratic formula which is
-b ± [tex]\frac{\sqrt{b^{2} -4ac}}{2a}[/tex]
Plugging the numbers from the equation in, it's
-(9) ± [tex]\frac{\sqrt{(9)^{2}-4(1)(13) } }{2(1)}[/tex]
This simplifies down to b = -6.307 or -11.693.
These are both real solutions.
Answer:
b = -6.307 or -11.693

pls help I'm confused, oh and can you also explain it. 15pts
Answer:
6
Step-by-step explanation:
This triangle is a special right triangle. In triangles with the angles 30, 60, and 90, the side opposite of the 30 degree angle will always be half the length of the hypotenuse. The hypotenuse is the longest side of a right triangle. In a 30 60 90 triangle, the long side will be equal to the short side multiplied by the squareroot of 3, but that is not needed for this problem. Since the hypotenuse is 12, the side opposite of the 30 degree angle, labeled "s h o r t" will be half of 12. Half of 12 is equal to 6, therefore the short side will be equal to 6.

Answer:
486√3 ft² ≈ 841.8 ft²
Step-by-step explanation:
The area of a regular hexagon with side length s is ...
A = (3√3)/2s²
For the side length of 18 ft, the area is ...
A = (3√3)/2(18 ft)² = 486√3 ft² ≈ 841.8 ft²

What is an equation of the line that passes through the points (-6,-5) and (-3,0)?put your answer in fully reduced form
Step-by-step explanation:
The equation is y = -3x + 6.
Answer:
3y = 5x + 15
Step-by-step explanation:
Slope = Change in y-cordinates
---------------------------------
Change in x-cordinates
= 0 - (-5)/-3 - (-6)
= 5/3
Using point (-3,0)
y - y1 = m(x - x1)
y - 0 = 5/3 (x - (-3))
y = 5/3 (x + 3)
Expand the bracket
y = 5x/3 + 15/3
Multiply through by 3
3y = 5x + 15
A point is reflected in the x-axis. The reflected point is (3,−9). What is the original point? The original point is ( , ). Question 2 What is the distance between the points? The distance between the points is units.
Answer:
The original point is [tex]P(x,y) = (3,9)[/tex].
The distance between the points is 18 units.
Step-by-step explanation:
The reflection of a point with respect to the x-axis is defined by the following operation:
[tex]P(x,y) = (x,y) \to P'(x,y) = (x, -y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Resulting point.
If we know that [tex]P'(x,y) = (3, -9)[/tex], then the original point is [tex]P(x,y) = (3,9)[/tex].
The original point is [tex]P(x,y) = (3,9)[/tex].
The distance between the points ([tex]d[/tex]), in units, is determined vectorially by the following expression, which is equivalent to the Pythagorean Theorem:
[tex]d = \sqrt{[P'(x,y) -P(x,y)]\,\bullet\,[P'(x,y) -P(x,y)]}[/tex]
[tex]d = \sqrt{(0,18)\,\bullet (0,18)}[/tex]
[tex]d = \sqrt{0^{2}+18^{2}}[/tex]
[tex]d = 18[/tex]
The distance between the points is 18 units.
Answer:(3,9) Distance 18 units.
Step-by-step explanation:
Emily walked around 2 parks. One measures 54 feet by 38 feet and other measure 32 feet by 22 feet. How much did she walk?
Answer:
292 feet
Step-by-step explanation:
If Emily walked round the two rectangular parks, she walked round the perimeter of the parks.
the total distance she walked can be determined by calculating the perimeter of each of the park and adding the perimeters together
Perimeter of a rectangle = 2 x ( length + breadth)
Perimeter of the first park = 2 x (54 ft + 38 ft) = 184 ft
Perimeter of the second park = 2x (32 + 22) = 108 ft
Sum of the perimeters = 184 ft + 108 ft = 292 ft
One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble. Each small bubble has a radius of 5 centimeters. What is the radius of the large bubble?
find area of 1 small bubble
πr² = π × 5²
= 78.54
total area of 4 small bubble
78.54 × 4 = 314.16
total area of 4 small bubble = area of big bubble
= 314.16
find it's radius
πr² = 314.16
r² = 314.16 ÷ π
r² = 100
r = √100
r = 10
Answer:
AREA OF LARGE BUBBLE=PI×R^2
AREA OF 1 SMALL BUBBLE =PI×r^2
then area of 4 small bubble =(PI×r^2)×4
now,
area of large bubble =area of 4 small bubble
PI×R^2=4×(PI×r^2)
R= 10 cm

Given that m∠a = 93° and m∠b = 71°, find m∠x and m∠y.
m∠x =
°
m∠y =
°
Step-by-step explanation:
angle b = 71°
so, x + b = 180° ( linear pair )
x + 71° = 180°
x = 180° - 71°
x = 109°
Now, a + y = 180° ( linear pair )
93° + y = 180°
y = 180° - 93°
y = 87°
Hence, the value of x is 109° and y is 87°.
