Answer:

a = 5

Step-by-step explanation:

According to the factor theorem, if x + 2 is a factor, then by dividing the polynomial by the binomial, we are meant not to have a remainder

In this case, the remainder would be zero

So, if we set the binomial equals zero and substitute the x-value into the polynomial, we are supposed to have 0

So we have this as;

x + 2 = 0

x = -2

-2^3 -2(-2)^2 -2(a) + 6 = 0

-8-8-2a + 6 = 0

-16 + 2a + 6 = 0

2a -10 = 0

2a = 10

a = 10/2

a = 5

What is the slope of the line that passes through the points (-10, 9)(−10,9) and (-12, 7) ?(−12,7)? Write your answer in simples
Mashutka [201]

Answer:

I Had A Problem In This Too Lol Here Was Correct For Me

Step-by-step explanation:

Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Durante a distribuição de bombons para seus netos, vovó Cláudia percebeu que, se distribuísse 11
Aleksandr [31]
<span>During the distribution of bonbons to her grandchildren, Grandma Claudia realized that if she distributed 11 chocolates for each of them, 10 candies would remain. In the meantime, distribute 13 chocolates each of his grandchildren, would lack 6. Based on this information, it is CORRECT to state that the difference between the number of candies and the number of grandchildren is A) 90. B) 30. C) -90. D) -30.

Let n=number of candies,
and c=number of grandchildren
The story expressed in modulo gives the two following equations:
then
mod(n,11)=10  (ten left if each given 11).............(1)
mod(n,13)=-6, or
mod(n,13)=7  (7 left if each given 13)

By enumerating (1), we have
10,21,32,43,54,65,76,87,98,109...
=> 8*11+10=98
By enumerating (2), we have
7,20,33,46,59,72,85,98,101...
=> 8*13-6=98
Hence there are 8 grandchildren and 98 candies.

The difference of the number of candies and the number of grandchildren is therefore 98-8=90.


Another way to get the number of grandchildren is
c=(10-(-6))/(13-11)=8
