Every real number is irrational this is true
Answer:
Problem 13: yes
Problem 14: no
Step-by-step explanation:
Problem 13:
Plug the values of x and y to solve.
-23 = -7(5) + 12
-23 = -35 + 12
-23 = -23
The values are equal, so the coordinates <u>do</u> solve the equation. It's a yes.
-----------------------------------------------------------------------
Problem 14:
Plug the values of x and y to solve.
-9 = -7(-3) + 12
-9 = 21 + 12
-9 = 33
The values are not equal, so the coordinates <u>do not</u> solve the equation. It's a no.

Answer:
4 + 13y
Step-by-step explanation:
The concept to answer this question can be bought from physics.
The Snell's law of refraction says that, the ration of sine of angle of incidence to the the sine of angle of refraction is constant for a given media.
This means;
(sinθ1)/(sinθ2) = k
Where θ1 = angle of incidence and
θ2 = angle of refraction
k = constant
(sinθ1)/(sinθ2) = k
sinθ2 = k/sinθ1
= k/sin25
= k/0.422618261
= 2.366k
The angle of refraction, θ2 = anti-sin(2.366k)
