You have the following equation:
|n| = 8 the two vertical bras | | means absolute value of variable n
when you have an equation with an absolute value you consider that n could be negative or positive, because the absolute value of a number always results in a positive number. Then, n can be 8 or -8, because |-8| = |8| = 8. Hence, you have
n = ±8
Answer:
X=2
Y=8
Step-by-step explanation:
Since both equations are equal to y we can equal both equations
2x+4=x+6
x=2
y=2(2)+4
y=8
Answer:
sin R = 20 / 29
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin R = opp / hyp
sin R = 20 / 29
