Answer:
620
Step-by-step explanation:
selling 400 doughnuts means selling 800 £ worth of doughnuts. 800 x 0.4 ( to find 40 percent) = 320, + 300 because the the fixed cost = 620. :)
One equation with 3 variables cannot be solved in the sense that you can find "the" 3 values for x, y and m. You can observe that this equation represents a family of straight lines with varying slope (depending on m).
Answer:
-5x ≤ 6x - 11
Step-by-step explanation:
Solving inequalities involves the same steps as equations with the exception that when multiplying or dividing by a negative coefficient of the variable, the inequality sign will flip. The solution to one of the inequalities given must be x ≥ 1. Given this answer, you can solve each to find the matching inequality:
-5x ≥ 6x - 11 or -11x ≥ -11 or x ≤ 1 (flip the sign due to negative coefficient)
-5x ≤ 6x - 11 or -11x ≤ -11 or x ≥ 1 (flip the sign)
5x ≤ 6x + 11 or -x ≤ 11 or x ≥ -1
-5x ≤ 6x + 11 or -11x ≤ 11 or x ≥ -1
Answer:
B: y= -2/7 x - 1/5
Step-by-step explanation:
Slope-Intercept Form equation: y=mx+b
m = slope
b = y-intercept
y = mx + b
y = -2/7 x + (-1/5)
