Answer:
Option 3rd is correct
The equation has no real number solutions because the discriminant is less than 0
Step-by-step explanation:
Discriminant(D)of a quadratic equation
is given by:

- If D = 0 , real zero of multiplicity 2.
- If D < 0, two zeros that are complex
- if D > 0, then two real zeros that are distinct.
As per the statement:
Anderson uses the discriminant to correctly find the number of real solutions of the quadratic equation:

On comparing the given equation with
we have;
a = 1, b = 4 and c = 8
then;

⇒
By definition;
Discriminant is less than 0
equation does not have real roots
Therefore, the equation has no real number solutions because the discriminant is less than 0
Verbal model: mile/inch=mile/inch
Proportion: 7/8÷3/10=x/1
Solve= 7/8*10/3=x/1
70/24=x/1
70=24x
x=35/12
The unit rate must be
Answer:
1/r^56
Step-by-step explanation:
Not sure if you did a typo there or what cus 7 x 8 should be 56
Whenever the power of a number is negative, you flip. So r^-7 becomes 1/r^7
Remove the bracket and distribute 8 to the power of 1 and r^7
1 to the power of 8 will still be 1, r^7 x 8 = r ^ 56
