Answer:
2
Step-by-step explanation:
First you need to factor your quadratic equation. You'll get (2x+1)(2x+1). Your two zeroes will be -1/2 and -1/2 with one being a, the other b. So then
a/b = (-1/2)/(-1/2)
and
b/a = (-1/2)/(-1/2)
Both reduce to 1. So a/b + b/a is 1+1=2
which number sentece states that x is at most 50
Answer:
The number sentence which states that x is at most 50 is x < 50.
Step-by-step explanation:
Which is the factored form of x(w – 1) + (W – 1)?
22 pts
Answer:
Solution given:
x(w – 1) + (W – 1)
distribute it:
xw-x+w-1
xw+w-x-1
take common from each term
w(x+1)-1(x+1)
take common again
(x+1)(w-1)
the factored form of x(w – 1) + (W – 1) is (x+1)(w-1).
What is the volume of this shape
Answer:

Answer:
Measure of segment JL is 20 cm.
Step-by-step explanation:
By applying geometric mean theorem in the given right triangle,
[tex]\frac{JM}{KM}=\frac{KM}{ML}[/tex]
[tex](KM)^2=(LM)(ML)[/tex]
[tex]8^2=(JM)(4)[/tex]
[tex]JM=\frac{64}{4}[/tex]
[tex]JM=16[/tex]
Since, [tex]JL=JM+ML[/tex] [By segment addition postulate]
[tex]JL=16+4[/tex]
[tex]JL=20[/tex] cm
Therefore, measure of segment JL is 20 cm.

need to know the answer
Answer:
Please find attached the required graph of the equation, y = x² - 2·x - 8, created using MS Excel
Step-by-step explanation:
The given function required to be plot is y = x² - 2·x - 8
Therefore, the coordinates of the vertex of the parabola formed by the equation (h, k) is given as follows;
h = -(-2)/(2×1) = 1
k = 1² - 2×1 - 8 = -9
The coordinates of the vertex = (1, -9)
The roots of the equation is given when y = 0, as follows;
At the roots, we have;
x² - 2·x - 8 = 0
By factorizing, we get
x² - 2·x - 8 = (x - 4)·(x + 2) = 0
Therefore. the roots of the equation are;
x = 4, and x = -2
The coordinates of the roots are;
(4, 0), and (-2, 0)
Two other points can be found at when x = 3 and when x = 0 as follows;
When x = 3, we have;
y = 3² - 2×3 - 8 = -5
(3, -5)
When x = 0, we have;
y = 0² - 2×0 - 8 = -8
(0, -8)
The five points are;
(1, -9), (4, 0), (-2, 0), (3, -5), (0, -8)
The graph of the equation created using MS Excel showing the five points is attached.
The graph of a linear function is given below.
What is the zero of the function?
A. -3
B. -3/2
C. -2/3
D. -2
A kite is flying on a string that is 73 feet long. The angle
the kite makes with the ground is 51 degrees. How high
is the kite flying?
Answer:
56.73 ft
Step-by-step explanation:
Given:
51° (angle)
73ft (hypotenuse)
With the given information use sin to determine the height of the kite.
sin51° = x/73
solve for x (height)
x= 73*sin51°
x= 56.73ft

Margaret works at a clothing store. Today she has sold only shirt and pants.The ratio of the number of shirts sold to the number of the items sold to 2/5. Which model shows this to ratio
Answer:
Shirt : Pant = 2 : 3 , & Pant : Shirt = 3 : 2 , Linear model can be used.
Step-by-step explanation:
Ratio of ' Number of shirts sold : Number of items sold' = 2 : 5
Let the common ratio be = x
Then, number of shirts sold = 2x. And, number of total items sold = 5x.
So, number of pants sold = Number of items sold - number of shirts sold = 5x - 2x = 3x
So, shirt to pant ratio = 2x / 3x = 2 : 3 .And, pant to shirt ratio = 3 : 2
This model can be shown in linear equation, as all are linear powered.
