Answer:
B
Step-by-step explanation:
To find the constant of proportionality between y and x, divide
for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
Using the method above, you should get:
Chart A = 2/5
Chart B = 1/5 (Correct Answer!)
Chart C = N/A

Answer:
The number is -2.
Step-by-step explanation:
From the word problem, we can figure out the equation for the unknown number (x).
8x-3=-19
We would then work out the equation to find x.
Add 3 to -19.
8x=-16
Divide -16 by 8.
x=-2
Answer:
The x-values cant repeat... Which is the first number in a ordered pair...
Step-by-step explanation:
L.maooo
we know that
The formula to calculate the slope between two points is equal to

we have

Step 1
<u>Find the slope GH</u>

substitute in the formula



Step 2
<u>Find the slope HJ</u>

substitute in the formula



Step 3
<u>Find the slope JG</u>

substitute in the formula



Step 4
Verify if triangle GHJ is a right triangle
we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

compare slope GH with slope JG
we have


-----> side GH and side JG are perpendicular
The triangle GHJ is a right triangle
