Answer:
Step-by-step explanation:
x = -2
so 0.5 x (2-(-2)) = 0.5 x 4 = 2
Answer:
y=4
Step-by-step explanation:
first you that the number outside of the parenthesis and multiply it by the numbers inside 3x3y (ignore the y for right now) and 6x3 now we have 9y-18=18 now we move the 18 so the y is by itself now we have 9y=36 divide both by 9 and you get your answer y=4
Answer: C
Step-by-step explanation: you just multiple 40 by 4
Answer:
D
Step-by-step explanation:
A sin 2.355/2.355 =0.01745240644 cos -2.355/2.355 root square
=180 so untrue not-1
B. sin =0.01745240644 cos = 0 so untrue not 1.
C sin = 0.01745240644 cos = 180 so untrue not 1
D = - 2.355/2.355= 0.01745240644 cos = 0.01745240644 = -1 so true.
As if we divide 1 into -1 = 1
When we divide 0.01745240644 / 0.01745240644 = will also = 1
The answer is -1 as inverse.
