Answer:

2) D, 3) A, 4) A, 5) B

Step-by-step explanation:

2) We proceed to demonstrate the statement algebraically:

(i) 3\cdot (m+2)-4\cdot (2\cdot m -9) Given.

(ii) 3\cdot m + 6 + (-4)\cdot (2\cdot m) +(-4)\cdot (-9) Distributive property.

(iii) 3\cdot m +6 +[(-4)\cdot (2)]\cdot m + (-4)\cdot (-9) Associative property.

(iv) 3\cdot m + 6 -8\cdot m + 36 (-a)\cdot b = -a\cdot b/(-a)\cdot (-b) = a\cdot b

(v) -5\cdot m +42 Distributive property/Definition of addition/Result.

Answer: D

3) We proceed to demonstrate the statement algebraically:

(i) -2\cdot (4\cdot x -5\cdot y - 5\cdot x ) Given.

(ii) -2\cdot [(4-5)\cdot x - 5\cdot y] Associative and distributive properties.

(iii) -2\cdot (-x-5\cdot y) Definition of addition.

(iv) (-2)\cdot (-x) + [(-2)\cdot (-5)]\cdot y Distributive and associative properties.

(v) 2\cdot x + 10\cdot y (-a)\cdot (-b) = a\cdot b/Result

Answer: A

4) We proceed to demonstrate the statement algebraically:

(i) -\frac{8}{9}\cdot \left(27+\frac{2}{3}\cdot x \right) Given.

(ii) \left(-\frac{8}{9} \right)\cdot (27) + \left[\left(-\frac{8}{9} \right)\cdot \left(\frac{2}{3} \right)\right]\cdot x Distributive property.

(iii) -24-\frac{16}{27}\cdot x \frac{a}{b}\cdot c = \frac{a\cdot c}{b}/(-a)\cdot b = -a\cdot b/Associative property/\frac{a}{b}\cdot \frac{c}{d} = \frac{a\cdot c}{b\cdot d}/\frac{a\cdot c}{b\cdot c} = \frac{a}{b}/Result

Answer: A

5) We proceed to demonstrate the statement algebraically:

(i) -\frac{1}{3}\cdot \left(3\cdot x -\frac{1}{2} \right) Given.

(ii) \left[\left(-\frac{1}{3} \right)\cdot 3\right]\cdot x +\left(-\frac{1}{3} \right)\cdot \left(-\frac{1}{2} \right) Distributive property.

(iii) -x +\frac{1}{6} (-a)\cdot b = -a\cdot b/(-a)\cdot (-b) = a\cdot b/\frac{a}{b}\cdot \frac{c}{d} = \frac{a\cdot c}{b\cdot d}/\frac{a\cdot c}{b\cdot c} = \frac{a}{b}/Result

Answer: B

What is the equation of the line that passes through the point (2,-4) and has a slope of -2
kvv77 [185]

Answer:

The answer is

\huge y =  - 2x

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

From the question we have

y + 4 =  - 2(x - 2) \\ y + 4 =  - 2x + 4 \\ y =  - 2x + 4 - 4

We have the final answer as

<h3>y = -2x</h3>

Hope this helps you
