Answer 1

Answer:

192 minutes

Step-by-step explanation:

if 100% is 8 hours

50% is 4 hours

75% is 2 hour

then 60% = 60/12.5 = 4.8 hours left

8-4.8 = 3.2 hours there

3.2x 60 = 192 minutes

calculate the coefficient b in the function f (x) = - x + b for which it holds that the graph passes through the point (-1,3)
Need if fast!

Answers

Answer:

b = 2

Step-by-step explanation:

For the graph to pass through the point, we have it that the coordinates of the point will work in the equation of the line

Hence, by substituting the x value, we can get the y value and by substituting the y value, we can get the x value

where f(x) is same as y in this case

Thus, we have it that;

3 = -(-1) + b

3 = 1 + b

b = 3-1

b = 2

Step-by-step explanation:

I used a calculator and paper and a pencil d---------b yeah :D yr welcome

Ok, so you would want to simplify both sides of the equation

(-1/3)(-12) + (1/3)(-12c)=-20 (here you distribute)

4+4c=-20

Then, subtract 4 from both sides

4c+4-4=-20-4

4c=-24

Then divide both sides by 4

4c/4=-24/4

c=-6
