3. replace x with 4 and solve:
3(4) - 5 = 12 -5 = 7
The answer is 7
4. Replace x with 6 in the equation for g(x) first:
2(6) -5 = 12-5 = 7
Now replace x with 7 in the equation for f(x)
2(7) +1 = 14 +1 = 15
The answer is 15

Hum, this problem was difficult. You use the next expression to solve this problem. \[\cos (A - B) = \cos A \cos B + \sin A \sin B \] \[\cos (A + B) = \cos A \cos B - \sin A \sin B\] \[\cos (A - B ) - \cos (A +B ) =2 \sin A \sin B\] So \[\sin A \sin B = 0.5 \left( \cos(A - B) - \cos(A + B) \right)\] A = 1.8 x, B = 0.5 x \[\sin (1.8x) \sin (0.5x) = 0.5\left( \cos(1.8-0.5)x - \cos(1.8+0.5)x \right)\]\[= 0.5 \left( \cos(1.3x) - \cos (2.3x) \right)\] It's finish !!
The slope intercept form is 
.
Solution:
Given data: slope = 
and y-intercept = –1
y-intercept means (x, y) = (0, –1)
Equation of a line for slope intercept form: 
Here, 
and 
.
⇒ 
⇒ 
Do cross multiplication.
⇒ 
⇒ 
⇒ 
Divide both sides of the equation by 4.
⇒ 
⇒
Hence the slope intercept form is .
