X=6
-6+7y=8
The answer is y= 2
A) Solve y=f(x) for x.
This instruction just means to manipulate the equation so that x is all by itself on one side. We can use a mixture of addition/subtraction and multiplication/division to do this with any equation.
f(x)=-3x+7
y=-3x+7
y-7=-3x
(y-7)/-3=x
b) Find the input to f(x) when the output is -8.
This means that it wants us to find the x value that provides a y value of -8. To solve this, we just need to plug -8 in for y and solve for x.
y=-3x+7
-8=-3x+7
-15=-3x
x=5
The decimal degree of the angle 12' 8" is 0.2022
<h3>How to change the decimal degree?</h3>
The angle measure is given as:
Angle = 12' 8"
As a general rule;
- 1 degree = 60 minutes
- 1 minute = 60 seconds
Where:
' represents minutes and " represents seconds.
So, we have:
Angle = 12/60 + 8/(60 * 60)
Evaluate the expression
Angle = 0.2022
Hence, the decimal degree of the angle 12' 8" is 0.2022

Step-by-step explanation:
f(x) = 2x - 5
is a line function.
the transformations are not changing the basic structure, so, also g(x) is a line function.
the negative sign reflected/mirrored the original line across the x-axis.
x+1 as argument translates the line 1 unit to the left.
+3 at the end translates the line 3 units up.
Answer:
10 miles per hour
Step-by-step explanation:
Average velocity=distance covered/time in hours
Distance=2 miles
time=12minute
change minutes to hour=12/60 =0.2hrs
v=2÷0.2
v=10miles per hour
