Okay so here we have the function f(x)=3x-6 if you plug in -2 to x you get -12 if you plug in -1 you get -9 and if you plug in 0 you get -6 add three each time
Answer:
X
Step-by-step explanation:
one is going vertical and the the other is horizontal
Answer:
13 3/4
Step-by-step explanation:
2 3/4 is 11/4 when converted into an improper fraction.
5 is 5/1 when converted into a fraction.
11*5 is 55 (numerators)
4*1 is 4 (denominators)
55/4 is 13 with 3/4 remaining
13 3/4
Answer:
-2 (negative 2)
Step-by-step explanation:
8÷2 =4
4-6 = -2
hope this helps
Answer:
There are 10⁻⁷ hydrogen ions in one-liter water
Step-by-step explanation:
Hi there!
a. If the pH = 7.0, then:
-log(H) = 7.0
multiply both sides of the equation by -1
log(H) = -7.0
Apply 10ˣ to both sides
10^(log (H)) = 10⁻⁷
(H) = 10⁻⁷
There are 10⁻⁷ hydrogen ions in one-liter water.
Why 10^(log (H)) = (H)?
Let´s consider this function:
y = 10^(log x)
(Apply log to both sides)
log y = log 10^(log x)
(Apply logarithmic property: log xᵃ = a · log x)
log y = log x · log 10
(log 10 = 1)
log y = log x
y = x
(since y = 10^(log x) and y = x):
10^(log x) = x
That´s why 10^(log (H)) = (H)
