Answer:
The roots of the equation 2m²+3=m are non-real roots.
Step-by-step explanation:
Given equation:
2m²+3=m
2m²-m+3=0
Here, from the equation we can obtain the following values:
a = 2, b = -1, c = 3
Discriminant of an equation is given as:
D = b²-4ac
= (-1)²-4(2)(3)
= 1 - 21
= -20
Discriminant can tell what kinds of roots the equation have.
In our case, the discriminant is less than 0.
When D < 0, the roots of the equation are complex conjugates.(non-real)
Answer:
If there are 2 quarters for every 3 nickels,
then there are quarters.
If there are 2 dimes for every quarter,
then there are dimes.
If the number of pennies and nickels together are equal to the number of dimes, then there are pennies.
Answer:
A
Step-by-step explanation:
I just plugged each variable into the equation. A is the only one that works.
To solve for x, put all of the angle measurements on one side of an equation and set it equal to 360, because the sum of any exterior angles is 360 degrees. hope this helped!
