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
Answer:
The answer is 30.
The least common denimonataor is 30 since 5 * 6 = 30, and there are no overlapping positive numbers before that.

Answer:
y = (2x/9) + 1
Step-by-step explanation:
Solving for y we get 3(-2y+x) = 5(-3y+x)+9
Expand the above we get -6y+3x=5(-3y+x)+9
which is -6y+3x = -15y+5x+9
then 9y = 2x+9
which y = (2x/9) + 1
⓵ You need to solve the left side first in order to isolate the × and find it’s value :
-7× + 6 = 27
-6 -6
↓
-7× = 21
÷-7 ÷-7
↓
× = -3
If you find it too difficult to divide a number by a negative, just divide 21 by 7 and always remember that when dividing, when the signs are different the answer is negative. So knowing that you could just divide 21 by 7, which is 3, and add a negative sign in front!

Answer:
You can use the Law of Sines for this problem, but what makes it tough at first glance is that they put a step in before you can use it directly. That first step is to get m∠C. When solving a triangle, always get the third angle if you know the other two so that you can use the Law of Sines (or Law of Cosines) more directly.
The sum of the angles of any triangles is 180°. We know the measures of the two other angles. So we subtract them from 180° to find that third angle.
180° - 76° - 66° = 38°
Now we can use the proportion from the picture. Angle B measures 76°, side b is our unknown, Angle C measures 38°, and side c measures 3 units.
sin 76° sin 38°
----------- = -----------
b 3
Cross multiply to find b (the side). We carry out five places in these calculations to get more accuracy.
3 * sin 76° = b * sin 38°
b = 3 * sin 76° 3 * 0.56611 1.69832
--------------- = --------------- = ---------------- = 5.73044
sin 38° 0.29636 0.29636
To the nearest tenth, b - 5.7 units.
