<h2>Answer:</h2>

The statement that is true about the graphs of all nth degree polynomials is:

B.) It goes up and down at most a total of n times.

D.) The number of x-intercepts is at most n.

<h2>Step-by-step explanation:</h2>

We know that the number of times the graph goes up and down depends on the number of distinct zeros of a polynomial and as we know that a polynomial of nth degree may have repetitive zero.

Hence, the graph of nth degree polynomial  goes up and down at most a total of n times.

Also, the number of x-intercept is the x-value of the point where the function is zero i.e. it depends on the number of zeros of polynomial.

Hence,  The number of x-intercepts is at most n.

Also, the end behavior of graph depends on degree as well as sign of the leading coefficient.

       Hence, correct options are:

      Option B and option: D

Give the slope and the y-intercept of the line y = x – 4.
Airida [17]

Given:

The equation of a line is

y=x-4

To find:

The slope and y-intercept of the line.

Solution:

We have,

y=x-4          ...(i)

The slope intercept form of a line is

y=mx+b            ...(ii)

Where, m is the slope and b is the y-intercept.

On comparing (i) and (ii), we get

m=1,b=-4

Slope of the line = 1

y-intercept of the line = -4

The coordinate form of y-intercept is (0,b). So, the y-intercept of the given line is (0,-4).

Therefore, the slope of the line is 1 and the y-intercept is (0,-4).

Shoshanna says that a triangle with side lengths 17m,8m and 15m is not a right triangle because 17 squared plus 8 squared equals
neonofarm [45]
Shoshanna is not correct
to find if a right triangle is actually a right triangle you have to do the two smaller values squared equals the larger value squared
(a²+b²=c²)

correct way to solve this problem:
a²+b²=c²
8²+15²+17²
64+225=289
289=289
so, this triangle is a right triangle

The answer is 40 because you have a ratio of 4:1 (16:4). If you multiply by ten, it becomes 40:10.
