Step-by-step explanation:
x² + 2x - 24 = (x + 6)(x - 4) = x² - 4x + 6x - 24 = x² + 2x - 24
True.
x² - 8x + 15 = (x + 5)(x +3) = x² + 3x + 5x + 15 = x² + 8x + 15
False.
3x² + 4x + 1 = (3x + 1)(x + 1) = 3x² + 3x + x + 1 = 3x² + 4x + 1
True.
5x² - 2x - 3 = (5x + 3)(x - 1) = 5x² - 5x + 3x - 3 = 5x² - 2x - 3
True.
4x² - 49 = (2x - 7)(2x + 7) = 4x² + 14x - 14x - 49 = 4x² - 49
True.

The distance y (in miles) that Train A travels in x hours is represented by the equation y=68x . The graph shows the distance that Train B travels. (0, 0) and (1, 64).
Answers
Answer:
For train A, the distance traveled as a function of time in hours is written as:
y = 68*x
For train B, we know that it's equation passes through the points (0, 0) and (1, 64)
Remember that:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then the slope for the equation of train B is:
a = (64 - 0)/(1 - 0) = 64
Then equation of train B is something like:
y = 64*x + b
Now, we know that it passes through the point (0, 0), this means that when x = 0, we also have y = 0, then if we replace these two values in the equation we get:
0 = 64*0 + b
0 = 0 +b
then b = 0
This means that the equation for train B is:
y = 64*x
Where again, y is the distance in miles and x is the time in hours.
If we look at both equations, we can see that train A has a larger slope, which means that for each unit of time, train A travels a larger distance, then we can conclude that train A is faster than train B.
In 1-4 match each scatter plot to the equation that could represent the equation of its trend line. (Not all of the choices will be used)

20% of $30 = $24
30% of $24 = 16.8
40% of $35 = $21
Explanation:
0.2 x 30 = 6
30 - 6 = 24
0.3 x 24 = 7.2
24 - 7.2 = 16.8
0.4 x 35 = 14
35 - 14 = 21

JKLM is a rectangle. if JL = 4x - 12 and MK = x, what is the value of x? what is the length of each diagonal?
Answers
Answer:
x = 4
The diagonals are both 4
Step-by-step explanation:
The fact that the two sides have no letter in common indicates that they are opposite each other or a diagonal. In this case the length is a diagonal. Diagonals in a rectangle are equal.
4x - 12 = x Add 12 to both sides
4x - 12 + 12 = x + 12 Subtract x from each side
4x - x = 12
3x = 12 Divide by 3
3x/3 = 12/3
x = 4
One of the diagonals = 4 because it is x.

What is the sum of the geometric sequence 1, -6, 36, ... If there are 6 terms? (1 point)
Answers
Answer:
-6665
Step-by-step explanation:
The given GP is :
1, -6, 36, ...
Number of terms = 6
The sum of n terms of a GP is given by :
[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]
Here,
a = 1, n = 6, r = 36/-6 = -6
So,
[tex]S_6=\dfrac{1((-6)^6-1)}{(-6)-1}\\\\=-6665[/tex]
So, the sum of th GP is -6665.

Answer:
x = 2.5
y = 5
Step-by-step explanation:
2x + 3y = 20
2x + y = 10 then y = 10 - 2x
substitute for y:
2x + 3(10 - 2x) = 20
2x + 30 - 6x = 20
reduce:
-4x = -10
divide both sides by -4:
x = 2.5
y = 10 - 2(2.5) = 5
check:
2(2.5) + 3(5) = 20
20 = 20
and
2(2.5) + 5 = 10
10 = 10
