Answer:
200
Step-by-step explanation:
(80×20)/8
y is equal to 200
Well 42 divided by 2 is 21. than to double check you can do 21 plus 21 equals 42.
Answer:
the slope is 1
Step-by-step explanation:
The linear equation is y=x+2
<u>Given</u>:
The given inequality is 
We need to determine the solution of the inequality in interval notation.
<u>Solution of the inequality:</u>
The solution of the inequality can be determined by simplifying the inequality.
Thus, we have,


Subtracting both sides by 3, we get;

Subtracting both sides by 2u, we have;

Dividing both sides by 4, we get;

Writing it in interval notation, we get;

Thus, the solution of the inequality is
