1 21v - 21
2 3n - 12
3 48x + 18
4 -3b + 9
Answer:
y = -3x - .25 or y = -3x + -.25
Step-by-step explanation:
y = slope (x) + y-intercept
-4 = -3(1.25)+b
-4 = -3 .75 + -.25
-4 = -4

Step-by-step explanation:
For a line you would draw a straight line with arrows on each end and for a ray you would draw a straight line with an arrow on only one end (depends on which way ray is pointing)

Answer:
No answer as written. 16 if we add an equals sign.
Step-by-step explanation:
As written, there is no "=" sign in either expression. That means they are only expressions, not equations. x can be anything. 10, 12345, 0.00000343345567788, etc. There is nothing that restricts the value of x.
If we set the two expressions equal to each other, we can calculate a value of x:
(2x + 30) = (5x - 18)
3x = 48
x = 16
