the selling price of an item is $650 marked up from the wholesale cost of $450. Find the percent markup from wholesale cost to selling price

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

i think the answer is 90 hope this

answer: the answer to this problem is yes because 4n + 4 does equal 2m - 6

step-by-step explanation: first you have to calculate 2m - 6 second you have to calculate 4n + 4 finally you have to get your answer

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
