Answer:
B (-2, 0)
Step-by-step explanation:
put the first equation in for y in the second equation - watch the negative
2x - (x +2) = -4
2x - x -2 = -4
x = -2
plug this x back in to find y
y = -2 + 2 = 0
Answer:
B
Step-by-step explanation:
plug in the answers given into both equations to see if the statements true
y=x+2
0=(-2)+2
0=0
2x-y=-4
y=2x+4
0=2(-2)+4
0=0

Answer:
1. B 2. D
Step-by-step explanation:
so it is compounded 4 times in a year in 4 years we can take it as 16 terms
a=6700(1+3.3/100)^16
a=6700(1+33/1000)^16
a=6700(1000/1000 + 33/1000)^16
a=6700(1.033)^16
a=6700*1.681144887891022
a=6700*1.6811
a=11263.23
Answer:
B. 1.17
Step-by-step explanation:
The z-score is:
z = (x − μ) / σ
z = (67.1 − 64.4) / 2.3
z = 1.17
we are given
radius is 8
![r=8](https://tex.z-dn.net/?f=%20r%3D8%20)
length of arc is 2pi
![l=2\pi](https://tex.z-dn.net/?f=%20l%3D2%5Cpi%20)
now, we can use formula
![\theta=\frac{l}{r}](https://tex.z-dn.net/?f=%20%5Ctheta%3D%5Cfrac%7Bl%7D%7Br%7D%20%20)
where
theta is central angle
![\theta=\frac{2\pi}{8}](https://tex.z-dn.net/?f=%20%5Ctheta%3D%5Cfrac%7B2%5Cpi%7D%7B8%7D%20%20)
