Answer:
Step-by-step explanation: (Equation 2) = 12(-12+9y/4) - 10y = -8
-144+108y/4 - 10y = -8
-144 + 108y - 40y/4 = -8
-144 + 108y - 40y = -32
108y - 40y = -32+144
68y = 112
Y= 1.64
2-4x+9y=14
12x-10y= -8
2-14+9y = 4x
-12 + 9y = 4x ( equation 3)
(Put in equation 2)
Answer:
5 and 4
Step-by-step explanation:
Answer:
- <u>Third choice: {3, 4, 6, 7, 9}</u>
Explanation:
<em>M ∪ N</em> means the union of the segments M and N. That is, the complete list of objects that are either in the set M or N.
The circle on the left of diagram shows that the elements inside the set M are 3, 4, 7 and 9.
The circle on the right of the diagram shows that the elements inside the set N are 4, 6 and 7.
The complete list of the numbers in either M or N is 3, 4, 6, 7, and 9 (you must not repeat the elements that belong to both sets but indicate them just once.
So, the set that represents M ∪ N is the third option {3, 4, 6, 7, 9}.
An arithmetic sequence starts with one number and you add the common difference to the previous term to get the current term
So...
f(x)=mx+b
m=common difference
b=starting point
f(11)=125=11m+b
-
f(1)=5=1m+b
--------
120=10m
Divide both sides by 10
12=m
Your common difference is 12.
For this case we have that by definition, the equation of a line in the slope-intercept form is given by:
Where:
m: Is the slope
b: Is the cut-off point with the y axis
We have the following equation:
We manipulate algebraically:
We subtract 10 from both sides of the equation:
We subtract 3x from both sides of the equation:
We multiply by -1 on both sides of the equation:
We divide between 5 on both sides of the equation:
Thus, the equation in the slope-intercept form is
