Option C. (x,y) → (x-7,y+5) is the correct answer

Further explanation:

Given

C(5,-4) — C'(-2, 1)

We will apply each translation rule one by one to check the correct algebraic rule.

A. (x,y) → (x - 2,y+1)

C(5, -4) → (5-2, -4+1) → C'(3,-3)

B. (x,y) → (x+7,y-5)

C(5, -4) → (5+7, -4-5) → C'(12,-9)

C. (x,y) → (x-7,y+5)

C(5, -4) → (5-7, -4+5) → C'(-2,1)

Hence, option C. (x,y) → (x-7,y+5) is the correct answer

3(x+y)=y

andrew-mc [135]

3(x+y)=y

y is not equal to zero

*Solution

1. The given equation is 3(x+y) = y and we are tasked to find the ratio between x and y. Distributing 3 to the terms in the parenthesis,

3(x+y) = y

3x + 3y = y

Transposing 3y to the right side OR subtracting 3y from both the left-hand side and the right-hand side of the equation would give

3x = -2y

Dividing both sides of the equation by 3,

x = (-2/3)y

Dividing both sides of the equation by y,

x/y = -2/3

Therefore, the ratio x/y has a value of -2/3 provided that y is not equal to zero.

Jill sold half of her comic books and then bought sixteen more. She now has 36. With how many did she begin?

Alex777 [14]

Answer:

$\frac{1}{2}x + 16 = 36$

40 comic books

Step-by-step explanation:

Let x be the Jill comic books.

Given:

Jill sold half of her comic books and then bought sixteen more. She now has 36.

$\frac{1}{2}\ (Jill\ books) + 16\ more\ books = 36$

$\frac{1}{2}\ (x) + 16 = 36$

$\frac{1}{2}x + 16 = 36$

Therefore the algebraic equation of the given statement.

$\frac{1}{2}x + 16 = 36$ --------(1)

Now we solve above equation for x.

Subtract by 16 both side of the equation 1.

$\frac{1}{2}x + 16 -16 = 36 -16$

$\frac{1}{2}x = 20$

Multiply by 2 both side of the above equation.

$2\times \frac{1}{2}x =2\times 20$

$x = 40$

Therefore, Jill had 40 comic books.
