Answer:
B
Step-by-step explanation:
The graph shows 3 spaces up every our on the y axis I hope this helped you! im very good at these so I can help is u have more questions! can I have brainliest? I was the first
a number can be written a "x".
"minus" is a key word for subtraction.
"is" is a key word for =.
So if we put that all together, we have
x-3=5
To solve it, we have to add 3, to cancel it out, and add 3 to 5.
x-3=5
+3 +3
x=8

hope it helps
Answer:
The length of the segment AB is √48
Step-by-step explanation:
Given the two equations, the idea is to find the solution to the system
y = x² + 9
y = 2x² - 3
you can use the equality method to find the "x" and "y" of the solution.
x² + 9 = 2x² - 3 ⇒ x² - 2x² = -3 - 9 ⇒ -x² = -12 ⇒ x² = 12 ⇒ x = ±√12.
With this value we return to the original equations and replace it to find "y" values.
y = (±√12)² + 9 ⇒ y = 21
The solutions to the system are (-√12, 21) and (√12, 21). Now you need to find the distance between this points.
d= √[(x2-x1)² + (y2-y1)²] ⇒ d = √48.
The length of the segment AB is √48.
Answer: 1.25
Step-by-step explanation: $15/$12= $1.25
$25/$20= $1.25
$35/$28=$1.25
To find constant proportionality you do your x value divided by your y value hoped this helped!
