If the discriminant of a quadratic equation is positive, which of the following is true of the equation?
Yanka [14]
For this case suppose that we have a quadratic equation of the form:
 ax ^ 2 + bx + c

 The solution to the quadratic recuacion is given by:
 x =  \frac{-b +/-  \sqrt{b^2 - 4ac}}{2a}
 Where,
 The discriminant is:
 b ^ 2 - 4ac

 When the discriminant is greater than zero, then the root is positive, and therefore, we have two positive real solutions.
 Answer:
 
B. it has two real solutions

If the measure of angle 5 is (11 x minus 14) degrees and x = 6, which expression could represent the measure of angle 2? 3 lines
g100num [7]

Answer:

The measure of angle 2 is 52°.

Step-by-step explanation:

Consider the below figure attached with this question.

It is given that

m\angle 5=(11x-14)^{\circ}

and x=6.

From the below figure it is clear that Lines 1,2 and 3 intersect each other at a point and form 6 angles.

It is clear that angle 2 and angle 5 are vertical opposite angles because these angles created by intersection of line 2 and line 3.

If two lines intersect each other then vertical opposite angles are congruent.

m\angle 2=m\angle 5                   (vertical opposite angles)

m\angle 2=(11x-14)^{\circ}

Substitute x=6.

m\angle 2=(11(6)-14)^{\circ}

m\angle 2=(66-14)^{\circ}

m\angle 2=52^{\circ}

Therefore, the measure of angle 2 is 52°.

One-half m minus three-fourths n equals 16, when n equals 8?
Cloud [144]

Hey!

------------------------------------------------

Expression:

0.5m - 0.75n = 16 (1/2m - 3/4n = 16)

------------------------------------------------

Solution:

0.5m - 0.75n = 16

0.5m - 0.75(8) = 16

0.5m - 6 = 16

0.5m - 6 + 6 = 16 + 6

0.5m = 22

0.5m/0.5 = 22/0.5

m = 44

------------------------------------------------

Answer:

\boxed{ \bf m~=~44}

------------------------------------------------

Hope This Helped! Good Luck!
