What's the operation between 2x and 4

Hello from MrBillDoesMath!



Answer:

x = -11, y = 6


Discussion:

I don't understand the answer shown -- "Doesn't Exist" -- especially as part of the problem statement is not displayed,  BUT

-6x + 3y = 84     =>    divide both sides by 3

-2x + y = 84/3= 28

-2x + y = 28          (A)


Multiply X = -23 + 2Y by 2 to get

2x = - 46 + 4y      (B)

Adding (A) and (B) gives


(-2x + y ) + (2x) =  28 + (-46 + 4y) =>

y = 28 -46 + 4y =>                                      as -2x + 2x = 0

y = -18 + 4y =>

18 = 3y =>

y = 6

From (A)    -2x + (6) = 28 or -2x = 28 -6 = 22 so x = -11



Thank you,

MrB

A triangle has vertices at B(−3, 0), C(2, −1), D(−1, 2). Which series of transformations would produce an image with vertices B″
vichka [17]

We must apply the <em>transformation</em> rules (x, y) → (- x, y) and (x, y) → (x + 1, y + 1) to generate the vertices B''(x, y) = (4, 1), C''(x, y) = (- 1, 0), D''(x, y) = (2, 3). (Right choice: B)

<h3>How to determine the right transformation rules for a set of three points</h3>

In this question we have three points on a <em>Cartesian</em> plane: B(x, y) = (- 3, 0), C(x, y) = (2, - 1), D(x, y) = (- 1, 2). First, we proceed to apply the <em>transformation</em> rule (x, y) → (- x, y):

B'(x, y) = (3, 0), C'(x, y) = (- 2, -1), D'(x, y) = (1, 2)

Then, we use the <em>transformation</em> rule (x, y) → (x + 1, y + 1):

B''(x, y) = (4, 1), C''(x, y) = (- 1, 0), D''(x, y) = (2, 3)

Then, we must apply the <em>transformation</em> rules (x, y) → (- x, y) and (x, y) → (x + 1, y + 1) to generate the vertices B''(x, y) = (4, 1), C''(x, y) = (- 1, 0), D''(x, y) = (2, 3).
