What is her answer? She needs to have an answer. If she doesn't have an answer, then I can't identify the mistake
Answer:
(4, 5 )
Step-by-step explanation:
Moving 7 left is in the x direction and means subtract 7 from the x- coordinate
Moving 5 down is in the y direction and means subtract 5 from the y- coordinate, that is
(11, 10 ) → (11 - 7, 10 - 5 ) → (4, 5 )
Gradient =
Change in Y
———————
Change in X
Change in Y is 18 - 14 = 4
Change in X is -20 - 30 = -50
Therefore the gradient is 4/-50 which is then simplified to - (2/25)
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
