Answer:
x = -9/2
Step-by-step explanation:
Substitute y = -6 in the second equation.
y = 4x + 12
-6 = 4x + 12
Subtract 12 from both sides.
-18 = 4x
Divide by 4.
-9/2 = x
Answer:
-1.17 volts
Step-by-step explanation:
The difference between "a" and "b" generally means "a-b". Here, the difference between the potentials is ...
-0.41 V - 0.76 V = -1.17 V
_____
Sometimes, when we talk about the difference, we mean the positive difference. If that is what is intended here, it is 1.17 volts.
F(2) = 3(2)^2 + 2(2) + 4
= 3(4) + 4 + 4
= 12 + 8
f(2) = 20
f(a+h) = 3(a+h)^2 + 2(a+h) + 4
= 3(a^2 + 2ah + h^2) + 2a + 2h + 4
f(a+h) = 3a^2 + 6ah + 3h^2 + 2a + 2h + 4
