Use synthetic division to find P (-10) for P(x)=2x^3+14x^2-58x
Savatey [412]
The polynomial remainder theorem states that the remainder upon dividing a polynomial p(x) by x-c is the same as the value of p(c), so to find p(-10) you need to find the remainder upon dividing

\dfrac{2x^3+14x^2-58x}{x+10}

You have

..... | 2 ...  14  ... -58
-10 |    ... -20  ... 60
--------------------------
..... | 2 ...  -6  ....  2

So the quotient and remainder upon dividing is

\dfrac{2x^3+14x^2-58x}{x+10}=2x-6+\dfrac2{x+10}

with a remainder of 2, which means p(-10)=2.

What is the equation of the line that passes through the points (-1,3) and (1,11)?
marta [7]

Answer:

y=4x+7

Step-by-step explanation:

You can find the slope of the line by using the formula of change and y over change in x. ∆y/∆x OR (y2-y1)/(x2-x1)

11-3=8

1--1=2

8/2=4

Let's plug in a y value 3.

3=4*-1+b

b=7

Once you found b rewrite your equation in slope intercept form.

y=4x+7

You can check this equation by plugging in the unused coordinate (1,11) and find it balances.

Give the answer of in the lowest terms 26/25 •15/28•8/39
DIA [1.3K]
(26/25) x (15/28) x (8/39)

Divide top and bottom by 3 :

(26/25) x (5/28) x (8/13)

Divide top and bottom by 5 :

(26/5) x (1/28) x (8/13)

Divide top and bottom by 4 :

(26/5) x (1/7) x (2/13)

= 52 / 455 = 0.11429... (rounded)
