Answer:
Solution set of the quadratic equation is, Empty set
Step-by-step explanation:
Given the quadratic equation:
Subtraction property of equality states that you subtract the same number to both sides of an equation.
Subtract both sides by 1 we get;

Simplify:

Division property of equality states that you divide the same number to both sides of an equation.
Divide both sides by 6 we get;

Simplify:

For any x in real number there does not exist any number x which satisfy
, therefore, there is no solution for this set of the quadratic inequality or in other word we can say that set of the solution is Empty set.
Hi,
I think this is the table, correct?
Number of Tubes 3 5 7
Cost ($) 12 20 28
we can calculate the prize as the number of tubes multiplied by 4:
3*4=12
5*4=20
7*4=28
which means that one tube costs 4 dollars!
However, in the store A two tubes cost 7, which means that one costs half of this -3.5
So Store B is more expensive (4 dollars per 4 rather than 3.5 as in Store A).
Distribute the -4. Then combine like terms.
24 - 4(5y - 6z) + 3y - 7z =
= 24 - 20y + 24z + 3y - 7z
= - 20y + 3y + 24z - 7z + 24
= -17y + 17z + 24
