Answer:
y = 9 + 19x
Step-by-step explanation:
To find the equation matching a set of data, you simply try a few values for x and see if by solving that side of the equation you get the value of y. If you do, you found your equation.
You have a big advantage here... since you have the value of y when x = 0.
When x = 0, y = 9, that's a very important data to have to simplify your research.
Let's try the value of 0 for x in each of the given equations:
y = 18 + 10 (0) = 18 --- NO
y = 9 + 19 (0) = 9 --- YES! We can confirm with another value of x:
y = 9 + 19 (1) = 28 --- YES! Confirmed!
y = 9 + 19x is your answer!
No, 0.7 is greater than 0.09
0.70 > 0.09
hope this helps
Answer: number 7. 7
Step-by-step explanation:
Simplifying
7X + 1 + -5X = 15
Reorder the terms:
1 + 7X + -5X = 15
Combine like terms: 7X + -5X = 2X
1 + 2X = 15
Solving
1 + 2X = 15
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + 2X = 15 + -1
Combine like terms: 1 + -1 = 0
0 + 2X = 15 + -1
2X = 15 + -1
Combine like terms: 15 + -1 = 14
2X = 14
Divide each side by '2'.
X = 7
Simplifying
X = 7
<h3>
Answer:</h3>
C. 4(x-3)-x
<h3>
Step-by-step explanation:</h3>
All of the given expressions are equivalent to 3x+12 except selection C. Using that in your equation makes it be ...
... 3(x +1) +9 = 4(x -3) -x
... 3x +12 = 3x -12
... 12 = -12 . . . . . <em>false</em>
There is no value of x that will make this true, hence NO SOLUTION.
_____
<em>Comment on the other choices</em>
3x+12 = 3x+12 has an <em>infinite number of solutions</em>, as <u><em>any</em></u> value of x will make this true.
We can conclude that All the data points are exactly the same. When we calculate one variable statistic and we find that the standard deviation is equal to zero most likely that we can conclude is that all the data points will be exactly the same.
