option b is ur answer

6 + 2/5b = 12

What does “b” equal?

Answers

Answer:

B = 15

Step-by-step explanation:

Combine multiplied terms into a single fraction

6 + 2b/5 = 12

Subtract 6 from both sides

6 + 2b/5 (-6) = 12 (-6)   = 2b/5 = 6

Multiply all terms by the same value to eliminate fraction denominators

2b/5 ( x 5) = 6 (x 5)

Simplify

2b = 30

What is the equation of the line that passes through the points (20,-3) and (0,2)?
A. Y=4x+2
B. Y=-4x+2
C. Y=-1/4x+2
D. Y= 1/4x+2

Answers

Answer:

C

Step-by-step explanation:

Put the equation in the form y = mx + b where m is the slope and b is the y-intercept

First, find the slope by doing the change in y divided by the change in x for the two points. This would be [tex]\frac{2-(-3)}{0 - 20} = -\frac{5}{20} = -\frac{1}{4}[/tex]. m = -1/4 in the equation.

So far, the equation is y = -1/4x + b

This means the slope is -1/4. Since it give you the y intecept, (0, 2), you know that b is 2 and the equation would be C. y = -1/4x + 2

How can you tell if 2 functions are inverses of each other?

Answers

"We know that for any two inverses f(x) = g(y), meaning that if we take f(x) for any x in the domain of f(x), then g(y), where y is the outcome of f(x), should output x." That is how you test to see if two functions are inverses.
