18/27 is the fraction you just said it
Answer:
The corresponding point is (1,-4)
Step-by-step explanation:
we know that
The point (1,-8) is on the graph of f(x)
so
that means
For 
therefore
For the function 1/2f(x)
For 
The corresponding point is (1,-4)
Answer:
What
Step-by-step explanation: I really knowing
12, 13, 15, 17, 17, 20 are the numbers in order
The median (middle number) would be 15 and 17
If there are 2 medians, you need to add both of them and divide by 2
15 + 17 = 32
32/2 = 16
So the median is 16
A) Jamar rewrote the first equation as -2x + 10y = -4. He had justification for doing this because he multiplied all parts of the expressions on both sides of the equation by the same factor, -2.
B) Jamar combined -2x + 10y = -4 with the other equation, 3x-10y=11, to get x=7. To do this, Jamar used combination, combining each of the different parts of the equations together. The y variables cancel out, and the x variables leave 1x, and we subtract 4 on the right side of the equation, leaving x = 7.
C)The solution of the system in an ordered pair (x,y) is (7, -1). You can get the y variable by substituting the x variable that we know equals 7, back into either of the beginning equations, to get the y value.
D) You know, without graphing, that the graph of 4x-15y=13 passes through the point whose coordinates are the solution of the system, because if we plug in the ordered pair (7,-1) into the equation it is a true statement, meaning that the variables are a solution this equation too. Therefore, if it <em>were</em> to be graphed, it would go through the point (7, -1).
