Answer:
x= 20,y= −36
Step-by-step explanation:
3x+2y=−12
2x+y=4
Subtract 2x
from both sides of the equation.
y=4−2x
3x+2y=−12
Replace all occurrences of y
with 4−2x
in each equation.

−x+8=−12
y=4−2x
Solve for x
in −x+8=−12
.

x=20
y=4−2x
Replace all occurrences of x
with 20
in each equation.

y=−36
x=20
The solution to the system is the complete set of ordered pairs that are valid solutions.
(20,−36)
The result can be shown in multiple forms.
Point Form:
(20,−36)
Equation Form:
x=20,y=−36
Answer:
p = 2a + 2b
Step-by-step explanation:
The perimeter p is the sum of the 4 sides , then
p = a + a + b + b = 2a + 2b
It is always possible for the product of a rational number and irrational number to result in a rational value.
Answer:
(0, 4) (-4, 3) (-4, 4)
Step-by-step explanation:
Translation rules:
Units UP - Add to the y-coordinate.
Units DOWN - Subtract from the y-coordinate.
Units RIGHT - Add to the x-coordinate.
Units LEFT - Subtract from the x-coordinate.
--------------------------------------------------------------------------------------------------------------
In this case, the word problem is asking for the points after a translation of 3 units up.
(x, y+3)
(0,1) → (0,4)
(4,0) → (4,3)
(4,1) → (4,4)
--------------------------------------------------------------------------------------------------------------Now it's time to reflect the new points over the y-axis.
When reflecting over the y-axis, the y-coordinate remains the same, but the x-coordinate becomes the opposite value. (-x, y)
(0,4) → (0,4)
(4,3) → (-4,3)
(4,4) → (-4,4)
