Answer:
f(x)=-1 and 15
Step-by-step explanation:
What you do is you put -2 and 2 into the x.
f(x) = -4(-2) + 7 = -1
f(x) = -4(2) + 7 = 15
f(x)=-1 and 15 are your answers.
Answer:
x = 
, y = 6
Step-by-step explanation:
5x + y = 7 → (1)
20x + 2 = y → (2)
Substitute y = 20x + 2 into (1)
5x + 20x + 2 = 7
25x + 2 = 7 ( subtract 2 from both sides )
25x = 5 ( divide both sides by 25 )
x = 
=
Substitute this value into (2) and evaluate
20( ) + 2 = y
4 + 2 = y , so
y = 6
Answer:
y = 7/3x + 2/3
Step-by-step explanation:
-7x + 3y = -10
3y = 7x - 10
y = 7/3x - 10/3
-4 = 7/3(-2) + b
-4 = -14/3 + b
2/3 = b
