To find the discriminant of the following equation you have to remember tha main formula : ax^2 +bx + c and the one for discriminant is <span>b^2 -4ac
So, now we can solve it </span>
, so the discriminants is 0 :)
Hope it's clear!
$10.50 gets taken off the original price. I divided $42 by 4 because 25 is 1/4th of 100. This got me $10.50. The original price ($42) minus $10.50 equals $31.50. So the item sells for $31.50!!!!
Because both lines DE and XY are parallel to one another, the 115° will be same for the line segment. XY
And because XY is a flat line, it's a straight angle. Meaning it's an 180° angle.
We need to find a value of x that when added 115° will equal 180°.
We can use this equation: x + 115 = 180
Subtract both sides 115.
x + 115 - 115 = 180 - 115
x = 65
So, x is equal to 65 degrees.
