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:
Step-by-step explanation:
Given that at a hockey game, a vender sold a combined total of 204 sodas and hot dogs.
The number of sodas sold was three times the number of hot dogs sold.
Let no of hot dogs be sold be x then no of sodas sold will be 3x
Total number of sodas and hot dogs 
the number of sodas =153
and the number of hot dogs sold=51
Answer:
true
Step-by-step explanation:
1 pt = 16 fl oz
Multiply both sides by 20.
20 pt = 320 fl oz
320 fl oz = 20 pt, so 320 fl oz is greater than 18 pt.
Answer:
- The angles do not share a special relationship.
Step-by-step explanation:
Angles 13 — 20 are right angles. Angle 12 is complementary to given angle 7, so is 90°-72° = 18°. Angle 10 is vertical with angle 12, so is also 18°.
There is no special relationship between right angle 14 and acute angle 10.
