Answer:
x = 2
y = 3
Step-by-step explanation:
Measures of opposite sides of a parallelogram are equal.
Therefore,
PQ = SR
2y + 2 = y + 5
2y - y = 5 - 2
y = 3
QR = PS
2x + 3 = y + 4
2x + 3 = 3 + 4 (y = 3)
2x = 7 - 3
2x = 4
x = 4/2
x = 2
Thus, for x = 2 and y = 3, PQRS is a parallelogram.
Answer:
H=horse
H=4(21-7)
Step-by-step explanation:
H=4(21-7)
H=4(14)
There were 56 horses.
Answer:
y =34.5
Step-by-step explanation:
9 times 2.50 = 22.5 + 12 = 34.5,
so y =34.5
16, add 16 to 8 and then the rest is simple
Answer:
B
Step-by-step explanation:
the standard form of a sine wave is
y = asinbx + c
where a is the amplitude , period = 
and c is the vertical shift
a = 
= 
= 1
period = 
b = 
= 3 , c = 0
hence y = sin 3x is the equation of graph
