There are many ways to check if the point (1,3) is a solution to the linear equation
.
Let us check it by expressing y in terms of x.
The given expression is 5x-9y=32. If we add -5x to both sides we will get:

Multiplying both sides by -1 we will get:

In order to isolate y, we will divide both sides by 9 to get:

Now let us plug in the given value of x=1 from the point (1,3). This should give us y=3. Let us see if we get y=3 when we plug x=1 in the above equation.


Thus, we see that when x=1, y=-3 and that
and hence we conclude that the point (1,3) is not a solution to the original given linear equation 5x-9y=32.
For a better understanding of the explanation given here a graph has been attached. As can be seen from the graph, (1,3) does not lie on the straight line that represents 5x-9y=32, but (1,-3) does lie on it as we had just found out.
Answer:
sparky 4 years older than cookie
Step-by-step explanation:
s=c+4
since there nothing to add or subtract. you are just gonna take that 4 and since there is a plus sign you are gonna say older than.
hope this helps
The formula for finding time is the distance divided by the velocity.So the answer is 100÷30=3.3333...
Answer:
-15x - 5
Step-by-step explanation:
5x - 15 - 20x + 10
5x - 20x - 15 + 10
-15x - 5
Step-by-step explanation:
diameter= 8
radius=diameter/2
=8/2
=4
height=2
Volume =r2h
=4*2*2
=16
therefore the volume of the cylinder is 16 cm^3
