This is in the fourth quadrant where the cosine is positive
By pythagoras the hypotenuse is 5
so the cosine is 3/5 B
Answer: the correct answers is 0.35 or 7/20
Step-by-step explanation:
The x intercept of the line is at x = 10.
The x intercept is always the value of x when all other values are equal to 0. So in this case, we put 0 in for t and then solve.
-2x + 5t = -20
-2x + 5(0) = -20
-2x = -20
x = 10
Performing the indicated multiplication on the left side gives you:
8x-24=8x-24,
8x=8x
1=1
These expressions are true for any real value of x and thus has infinitely many solutions...
The answer would be 2010 I think! im SO sorry if its wrong! :3
