Consider the relationship 7r+6t=14 A. Write the relationship as a function r=f(t)

B. Evaluate f(-7)

C. Solve f(t)=32

9514 1404 393

  A. r = (-6/7)t +2

  B. f(-7) = 8

  C. t = -35

Step-by-step explanation:

A. To solve for r, undo what is done to r.

  7r +6t = 14 . . . . . . given

  7r = -6t +14 . . . . . subtract 6t

  r = -6/7t +2 . . . . . divide by 7

  f(t) = -6/7t +2

__

B. f(-7) = (-6/7)(-7) +2 = 6 +2

  f(-7) = 8

__

C. (-6/7)t +2 = 32

  -6/7t = 30 . . . . . . subtract 2

  -6t = 210 . . . . . . . multiply by 7

  t = -210/6 . . . . . . divide by -6

  t = -35

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

the reporter's right

1/4 = .25 / 25%
