Answer:
(x + 1)(x - 7) is the odd one.
Step-by-step explanation:
1) sum= 8
Product = 7
Factors = 1 , 7 {1*7 = 7 & 1+7 = 8}
x² + 8x + 7 = x² + x + 7x + 7
= x(x + 1) + 7(x + 1)
=(x +1 )(x + 7)
2) x² - 8x + 7 = x² -x -7x + (-1)*(-7)
= x(x - 1) - 7(x - 1)
=(x - 1)( x - 7)
3)Sum = 6
Product = -7
Factors = (-1) , 7 { -1 + 7 = 6 & (-1)*7 = -7}
x² + 6x - 7 = x² - x + 7x - 7
= x(x - 1) + 7(x - 1)
= (x - 1)(x + 7)
Answer:
(x+1)(x-7) is the odd one out

Step-by-step explanation:
y = x ^ 3 - 5x ^ 2 + 6x
Answer:
Step-by-step explanation:
y = x(x^2 -5x + 6) Factor out a common term (GCF)
y = x(x - 2) (x - 3) Factor the trinomial
(x - 2) = 0 (x - 3) = 0 x = 0
Therefore x = 2, 3, or 0

Dominic jumped from a height of 14.3 feet above the surface of a pool. He traveled 18.7 feet straight down into the water. From there he traveled up 25.55 feet to the top of the biggest water slide at the pool. What is the height of the tallest waterslide?
Answer:
21.15 ft
Step-by-step explanation:
18.7 - 14.3 = 4.4 = pool depth
25.55-4.4 = 21.15 = slide height
Answer:
The height of the tallest water slide is 58.55 feet.
Step-by-step explanation:
To find the height of the tallest waterslide, we need to add the height from the surface of the pool to the point where Dominic reached before going down the water slide and the height of the water slide itself.
Dominic jumped from a height of 14.3 feet above the surface of the pool and traveled 18.7 feet straight down into the water, so his total distance from the surface of the pool to the point where he started going up the water slide is:
14.3 feet + 18.7 feet = 33 feet
From there, he traveled up 25.55 feet to the top of the water slide, so the height of the tallest water slide is:
33 feet + 25.55 feet = 58.55 feet
Therefore, the height of the tallest water slide is 58.55 feet.

Explain how you can take an imaginary number and multiply it by another imaginary
number and get a real number.
Answer:
When you multiply two imaginary numbers, you are essentially multiplying them by itself or squaring them. If we recall, an imaginary number is the square root of -1. By squaring this number, you're eliminating the square root, ending up with -1 (aka a real number).

A rectangular water tank has the following dimension:
Length = 3 feet, Width = 2 feet, Height = 2.5 feet. Find the amount of water it can hold in cubic centimeter.
Answer:
424,752.7 cm³
Step-by-step explanation:
Since you need to convert from English units to Metric units, you can do that first.
Convert each measurement to centimeters instead of feet since your final answer is in cubic centimeters.
1 foot = 30.48 centimeters
Length = 3 ft 30.48cm
----- x ------------ = 91.44 cm
1 1 ft
Width = 2 ft 30.48cm
------- x ------------- = 60.96 cm
1 1 ft
Height = 2.5 ft 30.48cm
-------- x ------------ = 76.2 cm
1 1 ft
The volume is equal to L x W x H
91.44cm x 60.96cm x 76.2cm = 424,752.7 cubic centimeters

a) Find the center-radius form of the equation of the circle with center (0,0) and
radius 16.
Answer:
x^2+y^2=256
Step-by-step explanation:
The general formula for a circle is (x - h)^2 + (y - k)^2 = r^2; where (h , k).
Thus, (x - 0)^2 + (y - 0)^2 = (16)^2 is x^2 + y^2 = 256

8x − 7y = –5
–x + 4y = –15
Answer:
Therefore, the values of "x" and "y" are -1000/312 and -115/39 respectively.
Step-by-step explanation:
★ Solution :-[tex] \sf \leadsto 8x - 7y = -5 - - - (i)[/tex]
[tex] \sf \leadsto -x + 4y = -15 - - - (ii)[/tex]
By first equation,
[tex] \sf \leadsto 8x - 7y = -5[/tex]
[tex] \sf \leadsto 8x = -5 + 7y[/tex]
[tex] \sf \leadsto x = \dfrac{-5 + 7y}{8} [/tex]
Now, we can find the original value of y.
[tex] \sf \leadsto -x + 4y = -15[/tex]
[tex] \sf \leadsto \bigg( \dfrac{-5 + 7y}{8} \bigg) + 4y = -15[/tex]
[tex] \sf \leadsto \dfrac{-5 + 7y}{8} + 4y = -15[/tex]
[tex] \sf \leadsto \dfrac{-5 + 7y + 32y}{8} = -15[/tex]
[tex] \sf \leadsto \dfrac{-5 + 39y}{8} = -15[/tex]
[tex] \sf \leadsto -5 + 39y = -15(8)[/tex]
[tex] \sf \leadsto -5 + 39y = -120[/tex]
[tex] \sf \leadsto 39y = -120 + 5[/tex]
[tex] \sf \leadsto 39y = - 115[/tex]
[tex] \sf \leadsto y = \dfrac{ - 115}{39} [/tex]
Now, we can find the original value of x.
[tex] \sf \leadsto 8x - 7y = -5[/tex]
[tex] \sf \leadsto 8x -7 \bigg( \dfrac{ - 115}{39} \bigg) = -5[/tex]
[tex] \sf \leadsto 8x + \dfrac{805}{39} = -5[/tex]
[tex] \sf \leadsto \dfrac{312x + 805}{39} = -5[/tex]
[tex] \sf \leadsto 312x + 805 = -5(39)[/tex]
[tex] \sf \leadsto 312x + 805 = -195[/tex]
[tex] \sf \leadsto 312x = -195 - 805[/tex]
[tex] \sf \leadsto 312x = -1000[/tex]
[tex] \sf \leadsto x = \dfrac{-1000}{312} [/tex]

Answer:
c
Step-by-step explanation:
smart boi
Step-by-step explanation:
A = (3, 6)
B = (6, 9)
C = (9, 3)
first scaled down (dilated) by the factor of 1/3 in the direction of the origin = point (0, 0).
then moved left by 2 units and down by 3 units.
the dilation about the origin simply multiplies each coordinate by the scale factor.
Ad = (3×1/3, 6×1/3) = (1, 2)
Bd = (6×1/3, 9×1/3) = (2, 3)
Cd = (9×1/3, 3×1/3) = (3, 1)
to move 2 units to the left means to subtract 2 from the x coordinates.
to move 3 units down means to subtract 3 from the y coordinates.
A' = (1-2, 2-3) = (-1, -1)
B' = (2-2, 3-3) = (0, 0)
C' = (3-2, 1-3) = (1, -2)
therefore, B is the right answer option.
A bird park has black and white birds in the ratio of 8 to 2 as shown below:
What is an equivalent ratio for black birds to white birds? Explain how you arrived at your answer in complete sentences.
Answer:
4:1
Step-by-step explanation:
So, although the ratio 8:2 is technically correct, it is not in its simplest form. To get it into its simplest form you need to find the largest multiplying factor that is the same for both numbers. In this case, 2 is the largest factor because it goes into both 2 and 8. Now, you need to divide the entire ratio by 2 the reach the simplest form, so 8 divided by 2 equals 4, and 2 divided by 2 equals 1. This gives us our final ratio of 4:1.
