When x^3 + 2x^2 - 7x + a is divided by (x-2) the remainder is 4. Find the value of a. Please help
12345 [234]

Answer:

a = - 8

Step-by-step explanation:

A polynomial divided by factor (x - h) has a remainder given by f(h)

Here the divisor is (x - 2), thus f(2) gives the remainder, that is

2³ + 2(2)² - 7(2) + a = 4 ← 4 being the remainder

8 + 8 - 14 + a = 4, that is

12 + a = 4 ( subtract 12 from both sides )

a = - 8

How do the average rates of change for the functions f(x) = 2x2 and g(x) = 3x2 over the interval −3 ≤ x ≤ 4 compare?
DedPeter [7]
<h2>Answer with explanation:</h2>

The average rate of change for function f(x) over the interval a ≤ x ≤ b is given by :-

\dfrac{f(b)-f(a)}{b-a}

So, the rate of change for function f(x)=2x^2  over the interval −3 ≤ x ≤ 4 :

=\dfrac{2(4)^2-2(-3)^2}{4-(-3)}=\dfrac{14}{7}=2

The rate of change for function g(x)=3x^2  over the interval −3 ≤ x ≤ 4 :

=\dfrac{3(4)^2-3(-3)^2}{4-(-3)}=\dfrac{21}{7}=3

So, the rate of change for  g(x) is greater than f(x) over the interval −3 ≤ x ≤ 4.

A line passes through (0,4) and (3,0). Which equation does not represent the equation of this line?
Olenka [21]

Answer:

A

Step-by-step explanation:

use both points to find the slope using the equation

y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3

then the y int can be any y point, so either -2 or 4. in this case they used 4.
