Answer:
B. -21
Step-by-step explanation:
The keyword we have is "below zero". When using the term "below zero" to describe an integer, this means the integer would be a NEGATIVE number. The temperature is 21 degrees below zero meaning its integer form is -21.
For starters, v(x) is the same as y If you know how to graph a line in the form of y=mx+b you can graph this. By putting it in the order it becomes: y=2x-5. Slope of 2 and y intercept of -5. that's to graph it
Answer:
Third choice
Step-by-step explanation:
They are asking us to find the inverse of y=5x. To do this you just switch x and y and then remake y the subject of the equation (solve for y.)
y=5x
x=5y (I switch x and y)
x/5=y ( I divided both sides by 5)
Then you just replace y with the f^-1(x) thing
f^-1(x)=x/5
or
f^-1(x)=1/5x
