Answer:
C=14
Step-by-step explanation:
To find the minimum value, graph each of the inequalities. After graphing each inequality, test a point and shade the region that satisfies the inequality. Once all inequalities have been shaded, find the region where they all overlap. The region will be bounded by intersection points. Test each of these points into C=x+3y. The least value for C is the minimum.
(14,0) (0,17.5) (3.08,3.64)
C=14+3(0) C=0+3(17.5) C=3.08 + 3(3.64)
C=14 C=52.5 C=14
Answer:
BC = 25
Step-by-step explanation:
Since AB = AC, then substituting values gives
4x + 1 = 2x + 23 ( subtract 2x from both sides )
2x + 1 = 23 ( subtract 1 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Hence
BC = 3x - 8 = (3 × 11) - 8 = 33 - 8 = 25
