AlladinOne [14]
No, the answers are incorrect.
When reflected over the y-axis, if the x is positive, then it becomes negative, but if the x is negative, then it becomes positive. Also, the y will not change.
The answer should be 
X prime: (0,-6)
Y prime: (10,4)
Z prime: (-3,-1)

Answer:

$(10, 0)$

Step-by-step explanation:

Let's try all the options:

$\left \{ {{2x + y = 20} \atop {4x-2y = 40} \right. $

Considering $(10, 0)$:

$\left \{ {{2(10) + 0 = 20} \atop {4(10)-2(0) = 40} \right. $\\

$\left \{ {{20 + 0 = 20} \atop {40-0 = 40} \right. $

$\left \{ {{20= 20} \atop {40 = 40} \right. $

Considering $(0, 10)$:

$\left \{ {{2(0) + 10 = 20} \atop {4(0)-2(10) = 40} \right. $\\

$\left \{ {{0 + 10 = 20} \atop {0-20 = 40} \right. $

$\left \{ {{10= 20} \atop {-20 = 40} \right. $

$\left \{ {{10\neq  20} \atop {-20 \neq 40} \right. $

Considering $(4, 2)$:

$\left \{ {{2(4) + 2 = 20} \atop {4(4)-2(2) = 40} \right. $\\

$\left \{ {{8 + 2 = 20} \atop {8-4 = 40} \right. $

$\left \{ {{10= 20} \atop {4 = 40} \right. $

$\left \{ {{10\neq  20} \atop {4 \neq  40} \right. $

Considering $(10, -10)$:

$\left \{ {{2(10) -10 = 20} \atop {4(10)-2(-10) = 40} \right. $\\

$\left \{ {{20 -10 = 20} \atop {40+20 = 40} \right. $

$\left \{ {{10= 20} \atop {60 = 40} \right. $

$\left \{ {{10\neq  20} \atop {60 \neq  40} \right. $

Jackson has 4 1/4 cups of chocolate. How can you write his amount of chocolate as a fraction greater than one
Zinaida [17]
If this is asking how to write this as a complex fraction, here's how:

First, do the whole number (4) multiplied by the diameter (4) to get 16. Then you take 16 and add this to the numerator (1) to get 17. Then your final answer is this number (17) over the original denominator (4), or 17/4

Hope this helps :)
