‘| |’ means modulus.
It’s turns the internal value positive.
We get a negative answer while finding the area of a triangle because there points in the quadrant other than the 1st quandrant i.e where all values are positive
Area of a triangle can never be negative, so we use modulus
Answer:
y=-6x/square root (4x^2-160
Step-by-step explanation:
hope this helps please mark me brainliest
Both x and y are 79 degrees because vertical angles are congruent.
Answer:
4+5x<50
Step-by-step explanation:
5n < 50 <--- subtracts 4 from both sides
n < 10 <--- divides both sides by 5
Check: testing n=0, we have 4 + 5(0) = 4 + 0 = 4 < 54, so yes it works
testing n=10, 4 + 5(10) = 4 + 50 = 54.
testing n=11, 4 + 5(11) = 4 + 55 = 59 <--- fails as expected.
X < 10, proven, verified, correct
