Answer:
Step-by-step explanation:
X={0,12,23}
Y={3,12,15}
X \ Y = { 0 , 23}
X/Y means the element should be only in X. We have remove the element in X if it is in Y
In this 0 and 23 is only in X
12 is X and Y. So it wont come in X/Y
Answer:
y=7, -3, 3, -9, 1 (in the empty boxes from left to right)
Step-by-step explanation:
Since y=x-2, all you have to do is take an x value from the top box and subtract 2 from that number to find the value of y.
Answer:
To solve linear equations with multiplication, you first determine that division is being used in the linear equation. Multiplication is the inverse (opposite) operation of division, so you can use multiplication to solve equations where you notice that a number divides the variable.
