Answer:
In both cases, "the set of all real numbers."
Step-by-step explanation:
y= -2x+3 is a linear function and is also a polynomial. Every polynomial has an unrestricted domain: "the set of all real numbers."
There is no restriction on y where this y= -2x+3 is concerned; y may have any value.
Answer:
-5
Step-by-step explanation:
x=? Y=x+3 ; y=-2
replace -2 with Y
-2 = x + 3
Then subtract 3 from both sides
-2 = x + 3
-3 -3
Then the positive and negative 3 cancels out leaving only
-5 = x
Answer:
20%
Step-by-step explanation:

Answer:
D) 65
Step-by-step explanation:
The formula for direct variation is
y = kx
where k is the constant of variation.
If we know y=32.5 and x=5, we can substitute in to calculate k
32.5 = k * 5
Divide each side by 5
32.5/5 = k
6.5 = k
So the equation is
y = 6.5k
Given x =10
y = 6.5*10
y = 65
Answer:x/4+3
Step-by-step explanation:
