I think it would be C because if you rotated it 90 degrees counter clockwise the A of X of x, y would then become negative

-y varies inversely with x. When y = 9.6, x = 12. What is the value of k, the constant of inverse variation?

alisha [4.7K]

Question 1:

For this case we have an equation of the form:

$y = \frac {k} {x}$

Where,

<em>k: inverse variation constant. </em>

Then, substituting values we have:

$y =\frac {k} {x}$

From here, we clear the value of k.

We have then:

$k = 9.6 * 12\\k = 115.2$

Answer:

the constant of inverse variation is:

$k = 115.2$

Question 2:

For this case we have:

$y = \frac {k} {x}$

Where,

<em>k: constant of variation. </em>

Then, substituting the value of the constant we have:

$y =\frac {5.6} {x}$

We now substitute the value of x:

$y = \frac {5.6} {4}\\y = 1.4$

Answer:

the value of y when x = 4 is: $y = 1.4$

<Q and <R are complementary angles. If m<Q = (31 - 3x)° and m<R = (19x - 5)°, find m<R

Sergio [31]

31-3x+19x-5=90

26+16x=90

-26 -26

--------------------

16x= 64

16x/16= 64/16

x=4

m <R=19 (4)-5= 71.
