Answer:11
Step-by-step explanation:
First multiply 4 and 2.
Which makes the equation 3+8
Which makes your answer 11
(x+y=31)2
2x-y=11
2x+2y=62
- 2x -y=11
3y=51
y=17
x+17=31
x=14
y-x=3
Answer:
3/2
Step-by-step explanation:
The multiplicative inverse also known as reciprocal implies it is something that is the opposite.
The given value is 2/3, so the opposite would just mean you flip the numerator and denominator. Thus, the reciprocal of 2/3 is 3/2.
Answer:B
Step-by-step explanation:
Answer:
f(g(-4)) = 13.
g(f(-4)) = -3.
Step-by-step explanation:
g(-4) = (-4)^2 + 3(-4) - 1
= 3.
so f(g(-4))
= f(3)
= 2(3) + 7
= 13.
f(-4) = 2(-4) + 7
= -1.
so g (f(-4))
= g(-1)
= (-1)^2 - 3 - 1
= -3.
