Answer:
Step-by-step explanation:
I'm going to write 105 as a sum of numbers on the unit circle.
If I do that, I must use the sum identity for sine.
Plug in the values for sin(60),cos(45), sin(45),cos(60)

Answer:
Step-by-step explanation:
The slope intercept form is .
The "" is the slope; which in this case is -3. So
.
The "" is the y-intercept, which is this case is the -8 because it is the 2nd number in the coordinate point.
This is why the answer is .
Cross-multiply so that 8(3x + 1) = 14(2x)
Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x
Subtract 24x from both sides:
8 = 4x
Divide both sides by 4:
x = 2
Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x
Subtract 24x from both sides:
8 = 4x
Divide both sides by 4:
x = 2
