Answer:
x = 400 when y = 100
Step-by-step explanation:
This is a question in relation to direct variation.
y ∝
y = k
Given that, y = 45, x = 81. Then;
45 = k
45 = 9k
k =
k = 5
Thus the relationship among the variables is;
y = 5
If y = 100, then;
100 = 5
=
= 20
x =
x = 400
Therefore, x = 400 when y = 100.
Conner is correct because when 2 exponents with the same base are multiplied, you add the exponents (for example, (x^3)*(x^4) = (x^7)
Answer:
<em><u>y</u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>/</u></em><em><u>3</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>-</u></em><em><u>9</u></em>
Step-by-step explanation:
y+6=1/3(x-9)
i.e y=1/3x -3-6
i.e, y=1/3x -9
it's in slope intercept form now,i.e, in form y=mx+c,where m is slope of st. line,here 1/3 is slope!
