Answer:
C. two real solutions
Step-by-step explanation:
Your quadratic matches the form ...
ax^2 +bx +c = 0
for the values a=2, b=7, c=-15.
The discriminant is ...
d = b^2 -4ac
For your values of a, b, c, the discriminant value is ...
d = 7^2 -4(2)(-15) = 169
The discriminant is positive, indicating there are two real solutions.
_____
When the discriminant is negative, there are no real solutions, only complex solutions.
When the discriminant is zero, there is one real solution.
__
This equation factors as (2x-3)(x+5) = 0 and has solutions x=3/2, x=-5.
Hey there!
If he has 24 cattle that eat 12 pounds of grain every day, then the amount of grain that they eat every day can be represented by the following equation:
p = 24 x 12 Multiply the two together, and the amount eaten each day is 288 pounds.
We can divide 10656 by 288 to figure out how many times 288 will go into 10656, which tells us how many days the supply will last.
10656 ÷ 288 = 37
So this means the food supply will last 37 days.
Hope this helps!
