alisha [4.7K]

Answer:

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

Step-by-step explanation:

  • Math session = 45 min = 3/4 hr
  • French session = 30 min = 1/2 hr
  • Number of math sessions = m, total math hours = 3/4m
  • Number of French sessions = f, total French hours = 1/2f

<u>Total hours constraint:</u>

  • 3/4m + 1/2f ≤ 30

<u>Number of session constraint:</u>

  • f ≤ 30

<u>So the system is:</u>

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

A line with a slope of 8 passes through the points (-1,1) and (0,k). What is the value of k?
Diano4ka-milaya [45]

Answer:

k = 9

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 8

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)

m = \frac{k-1}{0+1} = k - 1 = 8 ( add 1 to both sides )

k = 9
