So the whole goal of this is to get the variable (z) all by itself on one side with a coefficient (the number in front of the variable (z)) of one. All you have to do is add seven to each side to get z alone and then divide by two:
2z-7< or equal to 1
+7
2z< or equal to 8
/2
z< or equal to 4
The correct answer is y=3/2x-7 :)
Answer:
Ans: 0.0014
Step-by-step explanation:
-----------
Yes, because 11 2/3 is rounded to 12. and 2 5/6 is rounded to 3. 12 divided by 3 is 4. 4 2/17 is rounded to 4. 4 =4
Answer:
(x, y) = (3, 26)
Step-by-step explanation:
I like to solve systems of equations like this by graphing. A graphing calculator easily shows the solution for both x and y.
(x, y) = (3, 26)
__
As an alternative, here, the equations can be subtracted.
y = f(x)
y = g(x)
0 = f(x) - g(x) . . . . subtract the second equation from the first
0 = 11x -7 -(3x +17)
0 = 8x -24 . . . . simplify
0 = x -3 . . . . . . .divide by 8
3 = x
Now, we can substitute into either equation:
y = g(x) = 3(3) +17 = 26
The solution is (x, y) = (3, 26).
