Answer:
a, y =3/x
x = 0.5 => y = 3/0.5 = 6
x = 1 => y = 3/1 = 3
x = 2 => y = 3/2 = 1.5
x = 3 => y = 3/3 = 1
x = 4 => y = 3/4 = 0.75
b,
y = 3/x passes (0.5, 6) => A is correct
Hope this helps!
Answer:
60
Step-by-step explanation:
180-90-30=60
Answer:
x = 127 degrees
Step-by-step explanation:
By the external angle of a triangle theorem:-
x + 5 = 79 + m < ACB
m < ACB = 180 - x, so:-
x + 5 = 79 + 180 - x
2x = 79 + 180 - 5 = 254
x = 127 ( answer)
Answer:
x = -3
y = -11
Step-by-step explanation:
You want to substitute one of the y's
3x - 2 = 2x - 5
+2 +2
3x = 2x - 3
-2x -2x
x = -3
now that you have x, you need to substitute the x to get y
y = 3x - 2
y = 3(-3) - 2
y = -9 - 2
y = -11
or
y=2x-5
y = 2(-3) - 5
y = -6 - 5
y = -11
*they will both be the same no matter which equation you use
