Answer: I'm not sure exactly how you want this answered.
Step-by-step explanation:
Just by simplifying the expression, I got 
Triangle angles add to 180 degrees.
25+30=55 degrees, so x=180-55=125 degrees and y=180-x=55 degrees.
Decimal= a number that uses place value and decimal point to show part of a whole
tenth= one part of ten equal parts
hundredth=one part of one hundred equal parts
Answer: The solution is where both lines intersect. First find the x-coordinate which we will find by going to the left two units. That means x = -2. Now going up one unit, which gives us y = 1
(-2, 1)
Step-by-step explanation:
Answer:
Discriminant = 93, two real roots/solutions
Step-by-step explanation:
Discriminant = b² - 4ac = (9)² - 4(3)(-1) = 81 + 12 = 93
Since 93>0, the quadratic equation has two real roots/solutions.
