4. 1/12
5. still 1/12
Step-by-step explanation:
<span>The order was just switched around, and it is multiplication, so we can conclude that it is the "Commutative Property of Multiplication"</span>
An infinite amount seeing as you can have infinite of each number
Answer:
(f+g) (x) =0 for x=-2
Step-by-step explanation:
f(x) = x^2 – 2x, g(x) = 6x + 4,
(f+g) (x) =f(x) +g(x) =
(x^2 – 2x) + (6x + 4) =
x^2 – 2x+ 6x + 4=
x^2 +4x+4
(f+g)(x) =x^2 +4x+4=0 (quvadratic equation)
x^2 +4x+4=x^2 +2x*2+2^2=(x+2)^2
then
(x+2)^2 =0
x+2=0
x=-2
(f+g) (x) =0 for x=-2
Answer:
33 °C
Step-by-step explanation:
The bigger number is the <em>maximum</em> temperature.
Let’s call it T₂.
Then T₂ = 31 °C
=====
The smaller number is the <em>minimum</em> temperature
Let’s call it T₁.
Then T₁ = -2 °C
=====
The difference be the maximum and minimum temperature is
Diff = T₂ -T₁ Insert the values
Diff = 31 – (-2)
When you see a minus sign followed by a negative sign, turn them both into plus signs.
Then
Diff = 31 + (+2)
Diff = 31 + 2
Diff = 33 °C
