7+4b = 11b

= 11(6)

=66

From given,

Lina has a total of 7 + 4b beads

Emma buys and sells truck parts. She bought two tires for $35 each and later sold them for $65 each. She bought three rims for $75 each and later sold them for $136 each. She bought five headlight covers for four dollars each and later sold them for $15 each what is Emma’s total profit

Answers

Let us see her money earned first

65 * 2 + 136 * 3 + 15 * 5 = 613

versus how much she spent

35 * 2 + 75 * 3 + 5 * 4 = 315

613-315 = 298

Please help!! 10 pts.

Answers

Finally figured it out :D

The function rules is:
y = -5x - 1  


9 = -5(-2) - 1
4 = -5(-1) - 1
-1 = -5(0) - 1
-6 = -5(1) - 1
-11 = -5(2) - 1
