The discriminant is the part under the sqrt in the quadratic formula
for ax²+bx+c, the discriminant is b²-4ac
if the discriminant is
less than 0, then there are non-real roots
equal to 0, then there is a double root
greater than 0, then there are 2 real roots (may be rational or irrational)
so
1x²-5x+7
b²-4ac=(-5)²-4(1)(7)=25-28=-3
less than 0 so it is non real roots
answer is D
Answer:
The missing justification is the transitive property.
Step-by-step explanation:
The missing justification is the transitive property. The transitive property states that: If a = b and b = c, then a = c.
A<span>ngle ADB is 24 degrees and forming triangle BAD, the sum of the angles should be 180.
180- (24+116) = 40 degrees.

Answer:
x = -2
Step-by-step explanation:
Solution:
-5x - 5y = 25 -(1)
3x + 5y = -21 -(2)
Adding (1) and (2),
-5x - 5y + 3x + 5y = 25 - 21
-5x + 3x -5y + 5y = 4
-2x = 4
x = 4 / -2
Therefore, x = -2
PLZ MARK ME AS BRAINLIEST!!!
No. it isn’t. this is not in any form of a linear function
