X=15
3x+7+10x-22=180
13x-15=180
13x=195
X=15
Answer:
no, this is not a function.
Step-by-step explanation:
Since set A consists of inputs, an input has more than one output (set b), proving this is not a function.
I can't fill in the blanks since you did not show them in the picture.
However, I hope this helps :)
Answer:
The wording seems a bit off, I usually see it as deductive reasoning but yes, you take what you know and use that to "deduce", or find out something
Here is the correct format for the question
At 2:00 PM a car's speedometer reads 30 mi/h. At 2:15 PM it reads 50 mi/h. Show that at some time between 2:00 and 2:15 the acceleration is exactly 80 mi/h².Let v(f) be the velocity of the car t hours after 2:00 PM.Then . By the Mean Value Theorem, there is a number c such that 0 < c < with v'(c) = . Since v'(t) is the acceleration at time t, the acceleration c hours after 2:00 PM is exactly 80 mi/h^2.
Answer:
Step-by-step explanation:
From the information given :
At 2:00 PM ;
a car's speedometer v(0) = 30 mi/h
At 2:15 PM;
a car's speedometer v(1/4) = 50 mi/h
Given that:
v(f) should be the velocity of the car t hours after 2:00 PM
Then will be:
= 20 × 4/1
= 80 mi/h²
By the Mean value theorem; there is a number c such that :
with
Answer:
greater.
Step-by-step explanation:
7/8 divided by 3/4 is equals to 7/6, therefore it is greater than 3/4
