Money is earned by the hour.
Therefore all you have to do is divide the second column by the first column.

Caleb: 36.25/5; or $7.25 an hour.
Jeremy: 65.25/7.5; or $8.70 an hour.
Maria: 34.00/4.25; or $8.00 an hour.
Rosa: 54.00/8; or $6.70 an hour

This can be solved by using a simple algebraic equation.

For example, in the first column, Caleb worked 5 hours. We do not know how much he makes per hour, so let that be x. He earned a total of $36.25, so the equation can be written as 5x=36.25.

Divide by 5 on both sides, and you get x= 7.25

He earns $7.25 per hour of work.

Repeat this for all the workers:

Jeremy: 7.5x=65.25

x= $8.70

Maria: 4.25x=34.00

x= $8

Rosa: 8x=54.00

x= $6.75

Jeremy has the greatest hourly rate

X2 + 8x + 19 = 0 What is the equivilent that results from completing the square?

IrinaVladis [17]

Answer:

$(x+4)^2+3=0$

Step-by-step explanation:

Hey there!

Standard form is what this equation is in

Standard form is this: $ax^2+bx+c$

So order to complete the square, you need to take the $b$ term out of the equation, divide it by two, and then square it

In this case, the $b$ term is 8

We need to divide 8 by 2 ---> 4

Then square 4 ---> 16

So now you should add 16 to both sides

$x^2+8x+16+19=16$

Now you can simplify the LHS

$(x+4)^2 +19=16$

Now you subtract 16 from both sides

$(x+4)^2+3=0$

So this is as far as you can go since you cannot take the square root of a negative number
