When you write a function in the form 
, y is the dependent variable, and x is the independent variable.
So, if b is the independent variable, it means that we have to solve the expression for r.
To do so, we perform the following steps: start with
Add 12 to both sides
Divide both sides by 4:
So, we wrote the expression in the form 
, which means that r is the dependent variable and b is the independent variable, as requested.
Answer:
x=32
Step-by-step explanation:
2x+10=74
2x=64
x=32
Answer:
angle 1 (the last option)
Step-by-step explanation:
hope this helps!
A mountaineer climbed 1000 feet at a rate of x feet/hour
1000 = x ( t 1 ) eq1
5000 = X ( t 2) eq2 ( he climbed additional at different rate )
the rate was 10 feet / hour less than twice the first rate
X = 2x - 10 eq3
take eq1 and eq 2
( total time = t 1 + t 2 = T)
T = 1000/x + 5000/X
but X = 2x-10
T = 1000/x + 5000/( 2x -10)
T = 1000/x + 5000/( 2(x-5))
T = 1000/x + 2500 / (x-5)
Answer: m=1
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
Where
y2=12
y1=9
x2=6
x1=3
so plug in your values in the slop formula:
m=(12-9)/(6-3)
=3/3
=1
