This system has one solution y=8x+9, y=x^2+4x+13. What is the y coordinate
Digiron [165]

This system has one solution y=8x+9, y=x^2+4x+13. What is the y coordinate

y=8x+9<= y=8x+9 <== 8x+9: m=8

y=x^2+4x+13<= y <==x^2+4x+13: minimum (-2,9)

y=8x+9 and y.No solution

Question:

A sample of cans of peaches was taken from a warehouse, and the content of each can mearsed for weight. the sample means was 486g with stand deviation 6g. state the weight percentage of cans with weight:

Draw normal curve to help - split into 8 section ( i can't draw it here)

a) 34.13% of cans will be between 480g and 486g.

b) 13.59 + 2.15 + 0.13= 15.87% of cans greater than 492g.

Look at the Stand Dev Graph where the give you the number

Step-by-step explanation:

Let me give you a different question and i will answer it, which you help you answer your question.

Use the substitution method to solve the system of equations. <br> x+y=11<br> -x=-y-9
allochka39001 [22]
<h2>Answer:</h2>

Like you said, we need to use <u><em>substitution</em></u> to solve for y.

x + y = 11\\-1(-x = -y - 9)\\\\x + y = 11\\x = y + 9\\\\y + 9 + y = 11\\\\2y + 9 = 11\\\\2y = 20\\\\y = 10

Now that we've solved for y, we can plug in the number we got into one of the <u><em>original</em></u> equations. (You can choose either equation, but I will use the first one.)

x + 10 = 11\\\\x = 1

Now we have the solution of this system.

(1, 10)
