You are choosing between 3 phone plans, Utalk, myfone and Hello. The rates are as follows: Utalk - phone rental 16.50 with 9 cents a minute 52.5 Myfone - $12.99 with 10 cents a minute 52.99 Hello - $18.75 with 6 cents a minute. 42.75 This is the best plan You used 400 minutes in September. Find the bill for each phone plan and determine which plan is best for you.

Utalk: $36 dollars + 16.50 = 52.50. Myfone: $40 dollars + 12.99 = 52.99 or 60. Hello: $24 dollars + 18.75 = 42.75.

So you would have the best plan with Hello.

Step-by-step explanation:

0.09 x 400 = 36$

0.10 x 400 = 40$

0.06 x 400 = 24$

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
