Answer: The required example is x = 5.

Step-by-step explanation: Given that if x is a prime nu mber, then x+1 is not a prime number.

We are to give a counterexample for this.

Let us consider that

$x=5.$

Then, we know that x is a prime number.

But, we get

$x+1=5+1=6,$ which is not a prime number.

Thus, the required example is x = 5.

Find the x intercept and the y intercept of the graph of the equation <br> 2x+4y=8

maksim [4K]

Answer:

x-intercept: 4

y-intercept: 2

Step-by-step explanation:

finding the x-intercept:

first, substitute y = 0.

2x + 4 x 0 = 8

then, remove the 0.

2x + 0 = 8

then, divide both sides. 2x = 8

so, x = 4.

finding the y-intercept:

first, substitute x = 0.

then, solve.

2 x 0 + 4y = 8

so, y = 2.
