This Question: 1 pt Solve the system of equations by the substitution method.
12x + 3y = 22
- 4x = y + 8
Soloct the correct choice helow and if necessary fill in the answer box to complete your choice

no solution

Step-by-step explanation:

use the second equation because y is already by itself

-4 x = y + 8

y = -4x - 8

substitute:

12x + 3(-4x - 8) = 22

distribute the 3:

12x -12x - 24 = 22

0 - 24 = 22

-24 ≠ 22

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).
