Answer:
U (2,-1)
Step-by-step explanation:
if you replace x to 2, your answer will come out to be -1
You are suppose to subtract making it
X+7=13
-7=-7
______
X=6
-2(5y-20) - 5y = -5
-10y + 40 - 5y = -5
-15y + 40 = -5
-15y = -45, y = 3
x = 5(3) - 20
x = 15 - 20, x = -5
Solution: x = -5, y = 3... or (-5,3)
Step-by-step explanation:
The rule for a 90 degree counterclockwise is
(x,y) -> (-y,x)
so
C(-1,2) -> C'(-2,-1)
D(3,5) -> D'(-5,3)
E(1,2) -> E'(-2,1)
Answer:
Option C
-5, -2, 1, 3
Step-by-step explanation:
to get the list that orders the numbers from the least to the greatest, we need to, first of all, know the smallest and the largest numbers.
The largest number is easy to guess - it is undoubtedly 3.
However, the smallest number may be a bit tricky because we are dealing with negative numbers. When dealing with negative numbers, the numbers with greater magnitudes are actually smaller. This means that -5 is less than -3, which is less than -2, and so on.
Coming back to our question, we can now order the numbers as -5, -2, 1, 3 which is option C
