Answer:
It will take 100 additional minutes for the two plans to cost the same.
Step-by-step explanation:
Tim is choosing between two cell phone plans, Cingular and Verizon. They offer the same amount of free minutes.
Cingular's plan charges $39.99 per month with additional minutes costing $0.45.
Verizon's plan costs $44.99 with additional minutes at $0.40
Let a = the number of additional units that it will take the two plans to cost the same.
This means total cost of Cingular's plan additional minutes will be 0.45a and total cost of Verizon's plan additional minutes will be 0.4a
For the two plans to cost the same,
39.99 + 0.45a = 44.99 + 0.4a
0.45a - 0.4a = 44.99 - 39.99
0.05a = 5
a = 5/0.05 = 100

(1) 4mn × 6mp × 3mnp
= 4 × 6 × 3 ( mn × mp × mnp)
= 72 × (m³n²p²)

Answer: I think this is how we do it but i am not sure the answer is 48
Step-by-step explanation:
if the price increase by 3/4 then that mean it total will be 7/4 as 4/4 is it original price add so 7/4=84/x 84x4 is 336 336 divide by 7 is 48 to check 48 x 7/4 or 48 x 3/4 and add 48 if u math is correct than u should get 84
We have that
<span>y=-1/3(x+2)</span>²<span>+5
using a graph tool
see the attached figure
we know that
1) the graph open downward
2) the vertex of the graphic is the point (-2,5)
3) the axis of symmetry of the graph is x=-2
4) the x intercept values are (-5.873,0) and (1.873,0)
5) the y intercept value is (0,3.667)
