When solving using Elimination: After multiplying the top equation by -6, what would the equations look like?
x + 2y = 8
6x + 9y = 39
-6 . (x + 2y = 8)
6x + 9y = 39

-6 * (x+2y=8)

Step-by-step explanation:

1.) lost negative sign  

2.) correct

3.) lost negative sign

-6 * (x+2y=8) = (-6x-12y=-48)

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
