Answer:
Step-by-step explanation:
Begin to factor by using GCF by finding the greatest common factor. Here it is k.
We will rearrange and factor the trinomial.
Answer: Third Option
yes; k = 4 and y = 4x
Step-by-step explanation:
Observe in the values of x and y given that when x decreases the variable-y also decreases.
Then the variation is direct.
Then, if between any two points of the function, the rate of variation k remains the same then the variation is constant.
We can test whether these conditions are met by using the given points.
(-2, -8) and (-4, -16)
The rate of variation k for these points is:
Now we calculate the variation rate for the points
(-4, -16) and (-6, -24)
The rate of variation is constant and equal to 4.
Then the answer is yes; k = 4 and y = 4x
Answer:
False
Step-by-step explanation:
They both have 1 solution
15x + 4 = 3(6x +5)
15x +4 = 18x + 15 Multiple everything in the parentheses by 3.
4 = 3x + 15 Subtract 15 x from both sides
-11 = 3x Subtract 15 from both sides
-11/3 = x Divide both sides by 3
There is only one solution for this equation.
2x -8 = 8x + 36
-8 = 6x + 36 Subtract 2x from both sides
--44 = 6x Subtract 36 from both sides
-44/6 = x Divide both sides by 6.
There is only one solution for this equation.
Answer:
1. range is about 2 times or double the interquartile range.
2. 2.7222
Step-by-step explanation:
Mean: 15.9583
Median: 17
Range: 12
Lower quartile: 13
Upper quartile: 18.75
Interquartile range: 5.75
<u>2. Is also know as the (MAD) or Mean Absolute Deviation of a data set.</u>
I'm not sure if that's what you mean, but the difference between 6010 and 5060 is 950, so to find a number in a halfway between them I divided 950 by 2 (which is 475) and added it to 5060 (or substracted from 6010 - it's the same). Next I added the same number (475) to 6010. So finally it would like like this:
6,485 ; 6,010 ; 5,535 ; 5,060
