Answer:
f(2) = 36
Step-by-step explanation:
given f(x) = 
To evaluate f(2) substitute x = 2 into f(x)
f(2) = 6² = 6 × 6 = 36
Answer:
5
Step-by-step explanation:
13 = -2(y - 4) + 3y
13 = -2y + 8 + 3y
13 = y + 8
5 = y
y = 5
Answer:
i would say
y = ( 77 - x ) / 2
Step-by-step explanation:
2x + 4y = 123 + 31
2x +4y = 154
4y = 154 -2x
y = ( 154 - 2x ) / 4
y = ( 77 - x ) / 2
Answer:
20=5 because if a =(x+20)° then as my solution b=5
