Hi
3x-y = 4
so y = 4-3x = -3x +4
now you just have to remplace X by the first number given.
for 0 you have : y = -3*0 +4 = 4
so it's 0; 4
I let you do the others. No difficulties.
Answer:
Answer is 60 degrees.
Step-by-step explanation:
We know that in a right angled triangle if one leg is 1, and hypotenuse is 2,
then other leg = 
(By using Pythagorean theotrem)
Now consider a right angle triangle with hypotenuse 2 and one leg 1, and the angle between other leg and hypotenuse.
Since sin 30 = 1/2 we have cos 60= sin (90-60) = 1/2
Hence sin 60 = rt 3 /2
Using the above we get sin inverse of quantity square root of three divided by two is 60 degrees.

The age of Blain is 23 years old
<h3><u>Solution:</u></h3>
Let the age of Blain be "a" and age of Jillian be "b"
Given that Blain is two years older than three times Jillians age
So we can frame a equation as:
age of blain = 2 + 3(age of Jillian)
a = 2 + 3b ----- eqn 1
Also given that Jillian is also 16 years younger than Blain
Age of Jillain = Age of Blain - 16
b = a - 16 ---- eqn 2
Substitute eqn 2 in eqn 1
a = 2 + 3(a - 16)
a = 2 + 3a - 48
a - 3a = -46
-2a = -46
a = 23
Thus the age of Blain is 23 years old
