Step-by-step explanation:
yes it is
this table shows direct proportion
-7÷1
-14÷2
-21÷3
all give the same answer
if u look closely the constant is -7.if u times x by -7 it gives u y
y=-7x
pls mark me brainliesttt
15 you split it in half as it goes down
Did you get the answer me and you need help and no one dont want to help i hope you found the answer because i really need it math is very hard.
Answer:
see the explanation
Step-by-step explanation:
<u><em>The correct question is</em></u>
Use the discriminant to determine how many solutions are possible for the following equation (show work).
5x^2-3x+4=0
we know that
The discriminant for a quadratic equation of the form
is equal to
If D=0 then the equation has only one real solution
If D>0 then the equation has two real solutions
If D<0 then the equation has no real solutions (two complex solutions)
in this problem we have
so
substitute
so
The equation has no real solutions, The equation has two complex solutions
therefore
I know there are___No____
real solutions to the equation in problem 4 because ___the discriminant is negative___
