Answer:
(2.25,-0.5)
Step-by-step explanation:
If you were to graph the equations, they intersect at the points 2.25, and -0.5.
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:
The difference in unit prices of Jayden and Tia’s pack is $0.15
Step-by-step explanation:
Here in this question, we are interested in writing a statement describing the unit prices of both purchases.
For Jayden, 24 pack cost $7.20, thus one pack will cost 7.20/24 = $0.30
For Tia, the united price will be 2.70/6 = $0.45
So the difference in the unit prices of both will be $0.45-$0.30 = $0.15
Answer:
They are supplementary.
Step-by-step explanation:
If two angles form a linear pair, the angles are supplementary.
