Answer:
#43: D
#44: 11
Step-by-step explanation:
#43-
1. 2x + 4 =K= 2x+22
place function together
2. combine like terms
2x+4=k=2x+22
-2x -2x
4=K= 22
-4 -4
3. gives you the answer
which is K = 18
#44 f(x) = 2/3x + 3 .....f(12)
1. place 12 un the equation
f(12) = 2/3 × 12 +3
2. f(12) = 8+3
3. f(12)= 11
This is the best I can do
It should be C. I think the inverse is the completely mirrored/flipped one and if you took the coordinates of the original and C a d plotted them on a graph you'd get a mirror image, right? Don't hurt me if I'm wrong please
Answer:
gavin gets £51
sarah gets £34
pip gets £51
Step-by-step explanation:
3 + 2 + 3 = 8
136 ÷ 8 = 17, so 1 = 17
gavin = 3 x 17 (51)
sarah = 2 x 17 ( 34)
pip = 3x17 (51)
51+51+34= 136
Answer:
-15.96
Step-by-step explanation:
A conjugate is a binomial with the sign inside changed. So the conjugate of (1/5 + 4i) is (1/5 - 4i)
Set the original and the conjugate next to each other and F.O.I.L. Multiply the first numbers of each binomial, the 1/5 and the 1/5 to get 1/25. This is the "F."
Multiply the outer members, the 1/5 and the 4i to get - 60i. This is the "O."
Multiply the inner numbers ( the + 4i and the 1/5) to get + 60i. This is the "I."
Multiply the positive 4i and the negative 4i to get 16i squared
The positive 60i and the negative 60i cancel each other out.
The i squared changes into - 1. This makes the 16 negative.
Add 1/25 to - 16 to get - 15.96
