Practice translating figures. A triangle is drawn on the coordinate plane. It is translated 4 units right and 3 units down. Whic

h rule describes the translation? (x, y) → (x + 3, y – 4) (x, y) → (x + 3, y + 4) (x, y) → (x + 4, y – 3) (x, y) → (x + 4, y + 3)

When transforming right, y+. When transforming left, y-. When transforming up, x+. When transforming down, x-.

Since the transformation was r4 and d3, y+4 and d-3.

Therefore, the answer is (x, y) → (x + 4, y – 3).

Math help is this a inverse (show work) k(x)=3x^2-12

Paul [167]

Answer:

sqrt(1/2x+6) = h^-1 (x)

Step-by-step explanation:

To find the inverse, we exchange x and y and then solve for y

y = 2x^2 -12

Exchange x and y

x = 2y^2 -12

Solve of y

Add 12 to each side

x+12 = 2y^2

Divide by 2

(x+12) /2 = 2y^2/2

(x+12)/2 =y^2

1/2 x+6 = y^2

Take the square root of each side

sqrt(1/2x+6) = sqrt(y^2)

sqrt(1/2x+6) = y

This is the inverse

6 divided by $\frac{8}{9}$ is the same as 6/1 multiplied by 9/8, which gives us 7 as the whole answer. therefore, I think number 1 and 4 are the correct selections

Answer:

2.(b) w= 3

3. x= -3 or x= 3

Step-by-step explanation:

2.(b) <u>Method 1:</u>

$\frac{2w - 1}{5} + w + 2 = 2w \\ \frac{2w - 1}{5} = 2w - w - 2 \\$

Simplify:

$\frac{2w - 1}{5} = w - 2$

×5 on both sides:

$2w - 1 = 5(w - 2)$

Expand:

$2w - 1 = 5w - 10$

Bring constants to 1 side, w terms to the other:

$5w - 2w = 10 - 1$

Simplify:

$3w = 9$

Divide both sides by 3:

$w = 9 \div 3 \\ w = 3$

<u>Method 2:</u>

$\frac{2w - 1}{5} + w + 2 = 2w$

Multiply by 5 throughout:

$2w - 1 + 5(w + 2) = 5(2w)$

Expand:

$2w - 1 + 5w + 10 = 4w$

Simplify:

$7w - 9 = 4w$

+9 on both sides:

$7w = 4w + 9$

-4w on both sides:

$7w - 4w = 9$

Simplify:

$3w = 9$

Divide by 3 on both sides:

$w = 3$

3. $\frac{6x - 12}{3} + 4 = \frac{18}{x}$

Multiply by 3x on both sides:

$\frac{3x(6x - 12)}{3} + 3x(4) = \frac{3x(18)}{x} \\ x(6x - 12) + 12x = 3(18)$

Expand:

$x(6x) - x(12) + 12x = 54 \\ 6x^{2} - 12x + 12x = 54 \\$

Simplify:

$6 {x}^{2} = 54$

Divide by 6 on both sides:

${x}^{2} = 9$

-9 on both sides:

${x}^{2} - 9 = 0$

Factorise:

*Since a²-b²= (a +b)(a -b),

${x}^{2} - {3}^{2} = 0 \\ (x + 3)(x - 3) = 0$

Thus,

x +3= 0 or x -3= 0

x= -3 or x= 3
