Answer:
k(- 1) = 7
Step-by-step explanation:
Locate x = - 1 on the x- axis, go vertically up to meet the graph at (- 1, 7 )
then when x = - 1 , y = 7 , that is
k(- 1 ) = 7
0.8 is greater than 0.08, the reason for that is that 0.8 is equal to 8/10=80/100 and 0.08 is equal to 8/100. As a percentage, 0.8 would be 80% and 0.08 would be equal to 8%.
Answer:
Talking 65 minutes, $ 6.50 must be paid.
Step-by-step explanation:
Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:
0.10 x M = A
0.10 x 65 = A
6.50 = A
The vertex would be (-6,15)
