Answer:
(x,y)→(y,-x)
Step-by-step explanation:
Parallelogram ABCD:
A(2,5)
B(5,4)
C(5,2)
D(2,3)
Parallelogram A'B'C'D':
A'(5,-4)
B'(4,-5)
C'(2,-5)
D'(3,-2)
Rule:
A(2,5)→A'(5,-2)
B(5,4)→B'(4,-5)
C(5,2)→C'(2,-5)
D(2,3)→D'(3,-2)
so the rule is
(x,y)→(y,-x)
Answer:
16: 0.5, 5, 7.5
17: 62, 434, 682
18: 12.3, 62.5, 10
19: 1, 75, 300
Step-by-step explanation:
16: 9/18=0.5 so halve the numbers
17: 186/3=62 so multiply numbers by 62
18: 24.6/2= 12.3 so multiply by 12.3 and divide for the last one
19: 125/5=25 so for the first one divide by 25 and for the last two times by 25
Hello from MrBillDoesMath!
Answer:
-3x - 7
Discussion:
The order of operations states that multiplication and division are done before addition\subtraction. So
-2x +5/-5x - 7 =
-2x + (5/-5x) - 7 -
-2x -x -7 =
-3x - 7
Thank you,
MrB
The ladder and the wall form a right triangle.
The length is the hypotenuse = 15.
The base = 2*(15/5) = 2*3 = 6
Use pythagorean theorem to find other side of triangle:
