1 → B
multiply each term in the parenthesis by the 6 outside
6(b-7) = 6b - 42
2 → D
multiply each term in the parenthesis by the 3 outside
3(4x+6y+2) = 12x+18y+6
3 → A
the value outside the parenthesis is -1, hence each term inside is multiplied by -1
-1(6x+5y) = -6x -5y
Answer:
Yes
Step-by-step explanation:
After solving for the two values of a, the second inequality gives a value inside the range of the first inequality.
Answer:
Step-by-step explanation:
a.10^4=10000
b.10×9×8×7=5040
Answer:
The relation is 
Step-by-step explanation:
x and y are directly proportional:
This means that the equation is given by:

In which a is the multiplier that relates these two variables.
x= -4, y =6
We use this to find a. So




So
The relation is
