A.
Why: you'd move the decimal four places to the right. when you move the decimal to the left the number on the top right will be negative, to the left, positive.
Solve for x in -7x - 8y = 9
x = -9 + 8y/7
Substitute x = -9 + 8y/7 into -4x + 9y = -22
4(9 + 8y)/7 + 9y = -22
Solve for y in 4(9 + 8y)/7 + 9y = -22
y = -2
Substitute y = -2 into x = -9 + 8y/7
x = 1
Thus,
<u>x = 1</u>
<u>y = -2</u>
The answer to your question would be -2
Answer:
EG
Step-by-step explanation:
We automatically know that this is false because if we take the whole numbers in front of the numbers and do the operation
125-(-1)=1
125+1=1
126=1
very far
therefor since the decimals are less than 1 and the distance is more than 3, we conclude that this is false
