Answer:

Step-by-step explanation:

Reminder: slope-intercept form is y=mx+b where m is the slope and b is the y intercept

There are two points given on the line: (-1, 2) and (1, -4)

First, find the slope

Reminder: slope is y2-y1/x2-x1

Substituting the numbers into the equation gives -4-(-2)/1-(-1) which would make m=-3

Now that the slope is found, we can use slope point form

Reminder: slope point form is y-y1=m(x-x1)

Substituting the numbers would give this equation:

y-2=-3(x-(-1))

Simplifying the equation would give y=-3x-1.

OleMash [197]

To solve part a, do the following.
49.84-44.50=5.34
5.34/44.50=x/100
after solving the proportion, x would be equal to 12.
To solve part b, do the following.
50+12=62
To solve part c, do the following.
The amount of the tip is:
x/57.50=62/100
which is 35.65
The total bill is:
35.65+57.50=93.15

Use the boundedness theorem to determine whether the polynomial function satisfies the given condition. The polynomial f(x) = x4

7nadin3 [17]

Answer:

So f(x) has no real greater than 8. Step - by - step explanation is shown in the attachment.

Step-by-step explanation:

Let f ( x) be a polynomial with real coefficients and with a positive lending coefficient.

If f(x) is divided by x-c and

a) if c>0 and all number in the bottom row of the synthetic division are non negative , then f(x) has no zero greater than c.

b ) if c<0 and the number in the bottom row of the synthetic division alternate in sign then f (x) has no zero less than c

As shown in the figure

Since the number in the bottom row of the synthetic division alternate in sign

So f(x) has no real greater than 8
