Here is the equation:
⇒
You need to get "x" by itself so minus 3 from each side
⇒
⇒
Divide 8 by 2
÷
x=4
So each 4 is equivalent to 4
Lets check:
⇒
⇒
So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7
Answer:
Rel. Minimum- -0.3
Rel. Maximum - None
Increasing on: -0.3, infinity
Decreasing on: -Infinity, -0.3
Step-by-step explanation:
f(x) = 3x + 7x2 + x +5
To find the relative minimum, punch the equation into your graphing calculator and you should get -2/7 as your minimum. (Divide it for a decimal number)
There is no relative maximum because of this parent function type.
Increasing on: -2/7, infinity
And Decreasing on: -infinity, -2/7
Answer:
A ∩ Bc
Step-by-step explanation:
Home constructed of brick:
Event A
Home is less than or equal to 30 years old.
Event B is: {The home is more than 30 years old}
So the event home is less than or equal to 30 years old is the negation(complement) of B. So Bc.
And:
And means intersection.
We have the intersection of events A and the complement of event B, which is represented by:
A ∩ Bc
Answer:
10+5x
Step-by-step explanation: First 3x becomes a neggative thus saying there is a minus infront of it then combine the like therms with 8x making it 5x. Once you do that take 7 and add it to 3. Therefore the answer is 5x+10.
