it has no root
first make it common quadratic form
y = 5x² - 3x + 8
we take
a = 5
b = -3
c = 8
the to prove it doesn't have root. we using discriminant
D = b² - 4ac
D = (-3)² - 4*5*8
D = 9 - 160
D = - 151
D > 0 means the equation has 2 roots
D = 0 means the equation has 1 root
D < 0 do not have root because it doesn't have intercept on x-axis
Answer:
Step-by-step explanation:
4) parallel because 118° is a supplement to 62° and the corresponding angles are both 118°
5) NOT parallel. The labeled angles sum to 120° and would sum to 180° for parallel lines.
6) NOT parallel. see pic.
If parallel, extending a line to intersect ℓ₁ makes an opposite internal angle which would also be 48°. The created triangle would have its third angle at 180 - 90 - 48 = 42° which is opposite a labeled 48° angle, which is false, so the lines cannot be parallel
7)
b = 78° as it corresponds with a labeled angle above it
a = 180 - 78 = 102° as angles along a line from a common vertex sum to 180
f = is an opposite angle to 180 - 78 - 44 = 58° as angles along a line from a common vertex sum to 180
e = 180 - 90 - 64 = 26° as angles along a line from a common vertex sum to 180
c = 58° as it corresponds with f
d = 180 - 58 = 122° as angles along a line from a common vertex sum to 180
You divide the denominator into the numerator and that will get your answer which is 7.
