Answer: Find the discriminant
Check explanation
Step-by-step explanation:
b^2-4ac
if it is equal to 0 there is no solution
Greater then 0 there is 2 real solution
Less then 0 there is 1 real
3^2-4(2*-1)
9-4(-2)
9(8)
72 there is at least one real solution
Answer:
2
Step-by-step explanation:
We can set up equation for this one.
Let's say the number is X.
the sum of X and 14 can be expressed as : X+14
five times the sum of X and 14 can be expressed as 5(x+14)
and 5(X+14) = 80

The number is 2
Answer:
<u>y=90x−410</u>
Step-by-step explanation:
in point-slope form, this would be...
y−130=90⋅(x−6)<-----
If you convert this to slope-intercept form this would be...
y=90x−410
