Is this 2 different questions?
To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
Answer:
1. $60
2. 600 Calories were burned
3. D
Step-by-step explanation:
1. $75 x .20=$15
75-15=$60
2. What I started with is 200/40=5 calories burned per min
60 plus 60=120
5x120=600
3. It's the only option that has something decreasing. and there is a -5 which means it's getting subtracted or its decreasing.
Answer:
91
Step-by-step explanation:
12∣∣−x+3∣∣−5
Let x = 11
12∣∣−11+3∣∣−5
Do the absolute value first
12∣∣-8∣∣−5
Taking the absolute value, which means making it positive
12* 8 -5
Multiply and divide
96 -5

Answer:
y = -x +5
Step-by-step explanation:
Solving the given equation for y, we have ...
y = x +4
The slope of this line is the coefficient of x: 1. The slope of the perpendicular line will be the opposite reciprocal of this: -1/1 = -1. The y-intercept of the perpendicular line can be found from ...
b = y -mx = 8 -(-1)(-3) = 5
The perpendicular line has equation ...
y = -x +5
