The Vega family has a cell phone plan that costs $75 per month including taxes and fees. The plan lets the 5 members of the Vega family share 1,000 minutes of talk time per month and 400 text messages per month. Any minutes over 1,000 cost $1 per minute, and any texts over 400 cost $2 per text. Because of a family emergency, the family uses 1,040 minutes and 425 texts in March. Complete the example of an expression you could use to find the amount of the Vega's cell phone bill for March. 75 + 1 × ( − 1,000) + × (425 − 400)

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

d. all of the above

step-by-step explanation:

7x7=4 so if u carry the 9 it will be 33
