Answer:
Step-by-step explanation:
First you add up all the numbers - 8+7+5=20
Then you know 5 is 1/5 of 25
You know 5+5+5+5=20
ANSWER - 4/5
Answer:
<em>x = 1</em>
This is the equation that I interpreted:
6/(x) - 3 = 3/(x)
I have never worked with determining extraneous equations before, so I cannot answer the second part.
2745
Step-by-step explanation:
solve it like simultaneously
180x+120y greater than 5145
180x+120y greater than 2400
eliminate x
y will now be greater than 2745
Answer and explanation:
Given : The position of an object moving along an x axis is given by
where x is in meters and t in seconds.
To find : The position of the object at the following values of t :
a) At t= 1 s




b) At t= 2 s




c) At t= 3 s




d) At t= 4 s




(e) What is the object's displacement between t = 0 and t = 4 s?
At t=0, x(0)=0
At t=4, x(4)=14.24
The displacement is given by,



(f) What is its average velocity from t = 2 s to t = 4 s?
At t=2, x(2)=-1.76
At t=4, x(4)=14.24
The average velocity is given by,




Answer:
Perpendicular lines have a slope that is the negative reciprocal of the given line.
For example, if a given line has the slope 3/2, the the perpendicular line would have the slope -2/3.
For the given line: y = 4x - 7, the perpendicular line would have a slope of -1/4
There isn't enough info in the question to determine the y-intercept. Literally, any y-intercept could work and the line would still be perpendicular. Is the line supposed to pass through a certain point?
Your answer would be something like: y = -1/4 x + b
b is the y-intercept...if your question paper is multiple choice, choose the answer with the slope of -1/4. If it's supposed to pass through a certain point (x,y) replace x and y with the values in that point and solve for b to get the y-intercept.
