Write an inverse variation equation that relates x and y if y=-7 when x=-3 find y when x=-3

-7

Step-by-step explanation:

Inverse variation is characterized by the equation: y = k/x, where k is a constant.

Here, we're given values of y and x, so let's use them to find k:

y = k/x

-7 = k/(-3)

k = (-7) * (-3) = 21

Our equation is now: y = 21/x

Finally, plug in -3 for x:

y = 21/(-3) = -7

The answer is -7.

y = 21/x

y = -7

Step-by-step explanation:

y = k/x

-7 = k/-3

k = -7×-3 = 21

y = 21/x

y = 21/-3

y = -7

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
