Answer:
C. Their slopes are equal.
Step-by-step explanation:
Given : If two lines are parallel.
To find : which statement must be true.
Solution : We have given that If two lines are parallel.
We know that two parallel line have same slope
By rise over run :
Therefore, C. Their slopes are equal
Step-by-step explanation:
0 × <span>0 = 0
0 </span>× <span>1 = 0
1 </span>× <span>1 = 1
Which means multiplication is closed under {0, 1}
</span><span>1 </span>÷ <span>1 = 1
0 </span>÷ <span>1 = 0
</span>
Division is not closed under {0, 1}
1 + 1 = 2
Addition is not closed under {0, 1}
0 - 1 = -1
Subtraction is not closed under {0, 1} either
So it's only A. Multiplication which is closed under {0, 1}
Answer:
comparing both equation we get,
2X+1=X+9
or, X=8
Y=X+9
or, Y=17
therefore the required solution is (8,17)
