Katie earned $15 on mowing a neighbor's lawn. She then mows more lawns, charging $10 per lawn. She wants to earn a minimum of $65 for the weekend. Which of the following represents how many lawns she will need to mow to achieve her goal? *

15 + 10m ≥ 65
m ≤ 5
m ≥ 7

Option 4
m > 5

Option 6
(65 - 15) ÷ 10 ≤ m

6 lawns

Step-by-step explanation:

65 - 15 =50

50 / 10 =5

5+1 =6 lawns

The first option.

15 + 10m ≥ 65

Step-by-step explanation:

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

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
