Answer:

(x + 2) is a factor of f(x)

Step-by-step explanation:

Using the remainder theorem to divide f(x) by (x - h)

Evaluate f(h) and if equal to 0 then (x - h) is a factor

f(- 3) = (- 3)³ - 7(- 3)² + 36 = - 27 - 63 + 36 ≠ 0

f(- 2) = (- 2)³ - 7(- 2)² + 36 = - 8 - 28 + 36 = 0

f(- 6) = (- 6)³ - 7(- 6)² + 36 = - 216 - 252 + 36 ≠ 0

f(2) = 2³ - 7(2)² + 36 = 8 - 28 + 36 = 16 ≠ 0

Hence (x + 2) is a factor of f(x)

Given Below.

Step-by-step explanation:

(a)

$\left(-5y^2-9y-4\right)-\left(-2y^2-y+8\right)$

$\left-5y^2-9y-4\right+\left2y^2+y-8\right)$

$-3y^2 -8y -12$

(b)

$\left(3x-2\right)\left(5x^2-7x+2\right)$

$15x^3-21x^2 +6x - 10x^2 +12x - 4$

$15x^3-31x^2+20x-4$

two solutions of salt water contain 0.1% and 0.22% salt respectively. A lab technician wants to make 1 liter of solution which c

Mkey [24]

Answer:

0.25 L at 0.1% and 0.75 L at 0.22%

Step-by-step explanation:

We have to:

percent quantity

Salt solution # 1 0.1 x L

Salt solution # 2 0.22 (1 - x) L

Mixture 0.19% 1

We are left with the following equation:

0.1 * x + 0.22 * (1-x) = 0.19 * 1

solving:

0.1 * x + 0.22-0.22 * x = 0.19

0.1 * x- 0.22 * x = 0.19 - 0.22

-0.12 * x = -0.03

x = -0.03 / -0.12

x = 0.25

Which means

Salt solution # 1 0.1% 0.25 L should be used and for salt solution # 2 0.22% 0-75 (1 - 0.25) L
