37.4 degrees
because 1.3 times 12 is 15.6 and subtract that from 53
Answer:
$33
Step-by-step explanation:
60x/100 = 20
Cross multiplying 100 and 20
60x= 2000
Make x subject of formula
X = 2000/60 = 33
Hence original price is $33
Answer:
f=2
Step-by-step explanation:
0.3+0.5f-0.7
Move the varibale (0.5f) to the left-hand side and change it's sign to negative.
-0.5+0.3+-0.7
Move the constant to the right hand side and change it's sign
-0.5f=-0.7-0.3
Calulate the differnce
-0.5f=-1
divide both sides by -0.5
F=2
Answer:
1. Not a direct variation
2. Direct variation (constant= -4)
3. Direct variation (constant= -1)
Step-by-step explanation:
A direct variation is a function of the type
y = k*x, where k can be any real number
First case
1. y=4x+9
The term 9 interferes with the expression (it creates an offset for the value)
2. 2y=-8x
It is a direct variation, y = -4x
3. x+y=0
It is a direct variation, y = -x
Answer: 1
--------------------------------------------------------------
The equation y = 1*sin(2x) is in the form y = a*sin(bx-c)+d
where
a = 1
b = 2
c = 0
d = 0
The value of 'a' determines the amplitude
amplitude = |a| = |1| = 1
