If you decompose 9 you will get 3*3 so 9=3*3
If you decompose 12 you will get 2*6,then you can decompose 6 which 2*3 so 12=2*2*3
If you decompose 6 you will get 2*3 so 6=2*3
What do all of these numbers have in common?The 3.
So 3 is the greatest common factor.Now you just put the 3 in front and then open the bracket and divide each of the number by 3.
9/3=3
-12x/3=4x
6y/3=2y
So,this will be your answer 3(3-4x+2y)
It will never be the same, it is impossible.
Solution:
Here we have 2 system:
1. x + y = 42
2. 13x + 18y = 666
From equation 1.:
3. y = 42 - x
Substitute equation 3 into equation 2.:
13x + 18(42 - x) = 666
-5x + 756 = 666
5x = 90
x = 18
Since we got the value of x, then we will find the value of y. Substitute x into Equation 3:
y = 42 - 18 = 24
Answer:
Option B will be the correct one.
Step-by-step explanation:
See the attached graph.
Here, the graph of f(x) = |x - 7| - 3 is plotted.
Now, from the definition of the absolute value function
f(x) = x - 7 - 3 = x - 10, for x ≥ 7 ............ (1) and
f(x) = - x + 7 - 3 = - x + 4, for x < 7 ............. (2)
Now, for x ≥ 7, the plotted graph passes through the points (7,-3) and (10, 0) and equation (1) satisfies the points.
Again, for x < 7, the plotted graph passes through the points (4,0) and (0,4) and equation (2) satisfies the points.
Hence, option B will be correct one.
