Answers
Answer:
1 3/8 inches
Step-by-step explanation:
Total Length after adding 2 meteors of equal length = 16 inches
Let the length of the added meteor = x
To obtain the total length, we sum of each meteror multiplied by its frequency is obtained ;
(2/8)(1)+(3/8)(3)+(4/8)(2)+(6/8)(2)+(10/8)(1)+(11/8)(2)+(14/8)(2)+(15/8)(1) + 2x = 16
13.25 + 2x = 16
13.25 + 2x = 16
2x = 16 - 13.25
2x = 2.75
x = 1.375
1.375 = 1 3/8

Line l passes through point (0, -1) and is parallel to the line whose equation is y = -2x + 7. Which equation best describes the graph of line l? a) y = -2x + 6, b) y = 2x + 6, c) y = 1/2x - 1, d) y = -2x - 1
Answers
Answer:
[tex]y = -2x -1[/tex]
Step-by-step explanation:
Given
Passes through: (0, -1)
Parallel to: y = -2x + 7
Required
Determine the line equation
If the line is parallel to y = -2x + 7, then it has the same slope as y = -2x + 7.
For an equation of form: [tex]y = mx + b[/tex]
The slope is m
By comparison:
[tex]m = -2[/tex]
So, the slope of the extorted is -2.
The equation is then calculated using:
[tex]y = m(x - x_1)+ y_1[/tex]
[tex]y = -2(x - 0)-1[/tex]
[tex]y = -2(x )-1[/tex]
[tex]y = -2x -1[/tex]

Answers
Answer:
1) Function
2) Set Notation
3) Domains: {-4, -2, -1, 1, 3, 4}
4) Ranges: {-3, -2, 0, 2, 3}
Step-by-step explanation:
1) This is a function because the x-values are NOT repeated, and it passes the vertical line test.
2) This is a set notation because it has the symbol --> { } and it is "help define the elements of a set." You can search up "set notation" and you would get the idea. However, this is not an inequality because in inequality you would have, ex: x < 4 ≤ x
3) Domains mean the x-intercept. Remember to list domains from least to greatest!
4) Range means y-intercept. Remember to list the ranges from least to greatest! If a range is repeated then you do NOT need to re-write that number again.
factorize by splitting the middle term 6x-11x+4
Answers
Answer: (2x - 1)(3x - 4)
(split -11x as -8x and -3x)
Step-by-step explanation:
I am assuming that it is actually 6x^2 - 11x + 4
To find out how to split the middle term: The two numbers should multiply to a*c (6*4 = 24) and add to b (-11)
-8, -3 works
(6x^2 - 8x) + (-3x + 4)
2x(3x - 4) + -1(3x - 4)
(2x - 1)(3x - 4)

If you drive 5 miles east and then 4 miles south, how far are you, to the nearest tenth
of a mile from your starting point?
Answers
Answer:
6.4 miles
Step-by-step explanation:
5^2 + 4^2 = d^2
25 + 16 = d^2 = 41
d = 6.40 miles
The nearest tenth of a mile from your starting point is 6.4.
What is Pythagoras theorem?The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.
How to write nearest tenth?To round a number to the nearest tenth, we need to look to the right of the tenths place, which is the hundredths place. If the digit in the hundredths place is 5 or greater than 5, we need to add one to the digit in the tenths place. If it is 4 or less than 4, the tenths place digit remains the same. All the digits to the right of the tenths place should be changed to 0. That means, while rounding off a number to the nearest tenth, we will stop the rounding at the tenths place.
According to the question
If you drive 5 miles east and then 4 miles south
We have to find the nearest tenth of a mile from your starting point
From the diagram, we have to use Pythagoras theorem
D = [tex]\sqrt{4^{2} +5^{2} }[/tex]
D = [tex]\sqrt{16+25}[/tex]
D = [tex]\sqrt{41}[/tex]
D = 6.40312
Round 6.40312 to the required nearest tenth
D = 6.4
Hence, The nearest tenth of a mile from your starting point is 6.4.
