One meaning of a 'linear' equation is that if you draw the graph
of the equation, the graph will be a straight line.
That's an easy way to test the equation . . . find 3 points on the
graph, and see whether they're all in a straight line.
This equation is y = 4 / x .
To find a point on the graph, just pick any number for 'x',
and figure out the value of 'y' that goes with it.
Do that 3 times, and you've got 3 points on the graph.
Here ... I'll do 3 quick points:
Point-A: x = 1 y = 4 / 1 = 4
Point-B: x = 2 y = 4 / 2 = 2
Point-C: x = 4 y = 4 / 4 = 1
Look at this:
Slope of the line from point-A to point-B
= (change in 'y') / (change in 'x') = -2 .
Slope of the line from point-B to point-C
= (change in 'y') / (change in 'x') = -1/2 .
The two pieces of line from A-B and from B-C don't even have
the same slope, so they're not pieces of the same straight line !
So my points A, B, and C are NOT in a straight line.
So the equation is NOT linear.
Try it again with three points of your own.
Answer: C. LA
Explanation:
Angle W = Angle R (given)
VU = ST (given)
Angle U = Angle T = 90 (right angle of the right triangle)
Then we can say that triangle VWU = SRT (ASA)
It doesn’t have an inverse because it doesn’t pass the horizontal line test
its b because you can round 363 to 400 and 553 to 600 400 + 600 = 1000
QUESTION:- SOLVE THE EQUATION :- 3(x+2)=4x+1
ANSWER:-
STEP BY STEP
=> 3(x+2)=4x+1
Reason :- By multilying
=> 3x +6 = 4x+1
Reason:- By Subtracting with 3x on both sides
=> 6 = x+1
Reason:- By subtracting with 1 on both sides.( distribution property)
=> x = 5
HOPE IT HELPS YOU.
