a posteriori means as things are after any event.
Answer:
d. - 15
Step-by-step explanation:
The equation for direct variation is
y = kx
We know y =3 when x = -9
3 = k(-9)
Divide by -9
3/-9 = -9k/-9
-1/3 = k
The equation is then
y = -1/3 x
We know y = 5
5 = -1/3 x
Multiply each side by -3
-3*5 = -3*-1/3x
-15 = x
Hmm I use to know this wait a second I’ll answer it
The answer is -3
You use the formula y1-y2
———
x1-x2
-1 and 8 are your y’s
1 and -2 are your x’s
Your equation should look like this
-1-8 -9
—— = —— = -3
1-(-2) 3
I plugged the y’s and x’s into the formula.
I hope this helps!!
