Use technology to determine an approximate solution to the system y=-0.44x+12.6 and y=-7.21x-55.6. Explain the procedure.

The approximate solution to both systems is y = 17.03256 & x = - 10.074

Step-by-step explanation:

Because we have 2 equations we can simply graph each of them simultaneously and find the answer.

First we are going to graph y = - 0.44x + 12.6

Now.. We are going to graph y = - 7.21x - 55.6

Now that we have graphed both of our functions we know that the locations where the two lines meet otherwise known as the intersect is the solution to the equation.

Now that we know coordinate of x at the intersection point of the two lines is: - 10.074, we can input this number in as a substitute for our x because x = - 10.074

Therefor to verify,

y = - 0.44(-10.074) + 12.6

y = 17.03256

and now we substitute y into the other equation and find for x...

17.03256 = - 7.21x - 55.6

x = - 10.074

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

⭐⭐

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
