Answer:

n=11

Step-by-step explanation:

In order to solve this equation, we need to find out what n is. We have to get n by itself on one side of the equation. Perform the inverse operations to both sides of the equation.

19+n=30

19 is being added to n. The inverse of addition is subtraction. Subtract 19 from both sides.

19-19+n=30-19

n=30-19

n=11

Let's check out solution. Plug 11 in for n in the original equation.

19+n=30

19+11=30

30=30

The statement above is true, so we know our solution is correct.

Answer:

(3,0), (4,0), (5,0)

on the x-axis at 3, 4 and 5

Step-by-step explanation:

This function is a lovely swoopey cubic curve. If we finish factoring it, it's not to hard to see the x-intercepts. You set it equal to zero and solve it. The solutions are the x-intercepts (are the "zeros")

0=(x-5)(x^2-7x+12)

0=(x-5)(x-3)(x-4)

0=x-5, 0=x-3 & 0=x-4

x=5, x=3, x=4

This is where the graph crosses the x-axis.
