Answer:
Statements 2, 4, and 5
Step-by-step explanation:
15≥22+x
okay so that's
22+x≤15
and that is
x≤-7
the graph would not be a closed circle, it is a vertical line.
this means your 3 correct statements would be:
x less-than-or-equal-to negative 7,
–6 is part of the solution.
–7 is part of the solution.
the last two are true based on the inequality.
2/3= 0.6667 which you can figure out by 2÷3
3/4= 0.75 which you can figure out by 3÷4
because 0.75 is greater than 0.6667 she has enough to make the cake.
Answer:
Step-by-step explanation:
Method 1: Taking the log of both sides...
So take the log of both sides...
5^(2x + 1) = 25
log 5^(2x + 1) = log 25 <-- use property: log (a^x) = x log a...
(2x + 1)log 5 = log 25 <-- distribute log 5 inside the brackets...
(2x)log 5 + log 5 = log 25 <-- subtract log 5 both sides of the equation...
(2x)log 5 + log 5 - log 5 = log 25 - log 5
(2x)log 5 = log (25/5) <-- use property: log a - log b = log (a/b)
(2x)log 5 = log 5 <-- divide both sides by log 5
(2x)log 5 / log 5 = log 5 / log 5 <--- this equals 1..
2x = 1
x=1/2
Method 2
5^(2x+1)=5^2
2x+1=2
2x=1
x=1/2
