Answer:

The answer is C.

Step-by-step explanation:

In order to find the value of expression, you first have to solve x by substracting 6 to both sides then divide it by 5 :

$5x + 6 = 10$

$5x + 6 - 6 = 10 - 6$

$5x = 4$

$5x \div 5 = 4 \div 5$

$x = \frac{4}{5}$

Next, you have to substitute the value of x into the expression :

$let \: x = \frac{4}{5}$

$10x + 3$

$= 10( \frac{4}{5} ) + 3$

$= 8 + 3$

$= 11$

Factor the following equation to find its zeros.

Thepotemich [5.8K]

Answer:

A| 12, 3

Step-by-step explanation:

The polynomial can be factored by looking for factors of 36 that sum to -15. The sum being negative while the product is positive means both factors will be negative. The answer choices suggest ...

y = (x -12)(x -3)

A quick check shows this product is ...

y = x^2 -12x -3x +36 = x^2 -15x +36 . . . . as required

The factors are zero when x is either 12 or 3.

The zeros of the equation are 12 and 3.

Once you realize the constants in the binomial factors both have a negative sign, you can immediately choose the correct answer (A).

Or, you can use Descartes' rule of signs, which tells you that the two sign changes in the coefficients (+-+) mean there are 2 positive real roots.

If a,b,c,d, and e are non negative such that x^6-289x^4-x^2+289=(x-a)(x+b)(x_c)(x+d)(x^2+ex+1), what is the value of a+b+c+d+e?

Irina18 [472]

Answer:

Step-by-step explanation:

Hello,

If $X=x^2$ it becomes

$X^3-289X^2-X+289=(X^2-1)(X-289)$

and $289=17^2$

$X^2-1=(X-1)(X+1)=(x^2-1)(x^2+1)=(x+1)(x-1)(x^2+1) \\\\x^2-289=x^2-17^2=(x-17)(x+17)$

So,

$x^6-289x^4-x^2+289=(x^2-1)(x^2+1)(x^2-289)=(x-1)(x+1)(x+17)(x-17)(x^2+1)$

a = 1

b = 1

c = 17

d = 17

e = 0

Then a + b + c + d + e = 36

Thanks

A female cockroach can produce 80 offspring at a time. If half are female, and each female produces 80 offspring, how many cockr

IRINA_888 [86]

Ok if half are female that means 40 than 80 more for each of them because they all produce 80 so 80 times 40 = 3200 your gonna do the same 2 more times because of 3 generations so 3200 times 3 = 9600 in total
