Answer:
Domain: c)
Range: d)
Step-by-step explanation:
The domain means all of the possible x-values. To find the domain, find the leftmost and rightmost value of x. They are 0 and 8.5.
The range means all of the possible y-values. To find the range, find the lowest and higher values for y. They are 0 and 12.5.
"All numbers" means x or y can be any number, decimal decimal numbers. "Whole numbers" mean x or y can only be numbers that don't have decimals.
Both x and y can be decimal numbers because the graph is not broken up. If it could only be whole numbers, the graph would be dots.
Solve inequalities the way you would solve an equation except for this rule-
If you multiply or divide a negative, the sign must be switched.
Do the inverse of everything like in an equation-
4x-1> -9
+1 +1 (Add 1)
4x>-8
/4 /4 (Divide 4)
You are not dividing a negative number from another number. So keep the sign.
x>-2
Your answer is C.
6+y
Since increased (key word) means addition.
