Answer:
-25
Step-by-step explanation:
Essentially, y is your output and x is your input.
Here's your base equation: y = 2x + 5
Knowing the information above, let's plug it in:
-45 = 2x + 5
(Subtract 5 from both sides)
-50 = 2x
(Divide both sides by 2 to isolate x)
-25 = x
And there you go.
Answer:
input is -25
Step-by-step explanation:
y = 2x + 5
The output is -45 which is y
-45 = 2x + 5
Subtract 5 from each side
-45-5 = 2x
-50 = 2x
Divide each side by 2
-50/2 = 2x/2
-25 = x
