Answer: x = 0 y = –3
Step-by-step explanation:
We can solve this system by substitution.
use the second equation as a value for x.
Then substitute that value in place of x in the first equation and solve for y.
6x - 5y = 15 becomes
6(y + 3) - 5y = 15 Distribute 6 × parentheses
6y + 18 - 5y = 15 combine like terms
6y -5y + 18 = 15
y + 18 = 15 Subtract 18 from both sides.
y =15 -18
y = –3
Use this value for y in either equation to solve for x
6x - 5(-3) = 15
6x + 15 = 15 Subtract 15 from both sides, divide by 6 (seems silly!)
x = 0
OR in he second equation,
x = -3 + 3
Again, x = 0

Knowledge point: Trigonometry - tangent concept
Answer:2x
Step-by-step explanation:
Just plug in the domain values in the equation to find y.
f(x)=-x+4
f(-3)=-(-3)+4=3+4=7
f(-2)=-(-2)+4=2+4=6
f(-1)=-(-1)+4=1+4=5
f(1)=-1+4=-1+4=3
So the range is Option B : {7, 6, 5, 3}
