Answer: v = 2
Step-by-step explanation:
30-48v+12 = -54
-48v = -54-30-12
= ![\frac{-96}{-48}](https://tex.z-dn.net/?f=%5Cfrac%7B-96%7D%7B-48%7D)
v = 2
Answer:
![\frac{3}{b^{0}b^{4} }](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bb%5E%7B0%7Db%5E%7B4%7D%20%20%7D)
Step-by-step explanation:
Move
to the denominator in ![\frac{3b^{-4} }{b^{0} }](https://tex.z-dn.net/?f=%5Cfrac%7B3b%5E%7B-4%7D%20%7D%7Bb%5E%7B0%7D%20%7D)
using the negative exponent rule ![b^{-n} =\frac{1}{b^{n} }](https://tex.z-dn.net/?f=b%5E%7B-n%7D%20%3D%5Cfrac%7B1%7D%7Bb%5E%7Bn%7D%20%7D)
D. 20 it's a 30-60-90 degree triangle so because the length of the hypotenuse is twice the length of the shortest leg
Answer:
The second choice ![(7.6,8.8)](https://tex.z-dn.net/?f=%287.6%2C8.8%29)
Step-by-step explanation:
The missing image is attached
We use the section formula:
![(x,y)=(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%28%5Cfrac%7Bmx_2%2Bnx_1%7D%7Bm%2Bn%7D%2C%5Cfrac%7Bmy_2%2Bny_1%7D%7Bm%2Bn%7D%29)
We substitute
and m=5, n=9
![(x,y)=(\frac{5*16+9*3}{5+9},\frac{5*21+5*2}{9+5})](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%28%5Cfrac%7B5%2A16%2B9%2A3%7D%7B5%2B9%7D%2C%5Cfrac%7B5%2A21%2B5%2A2%7D%7B9%2B5%7D%29)
We simplify to get:
![(x,y)=(\frac{80+27}{14},\frac{105+10}{14})](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%28%5Cfrac%7B80%2B27%7D%7B14%7D%2C%5Cfrac%7B105%2B10%7D%7B14%7D%29)
This simplifies to:
![(x,y)=(\frac{107}{14},\frac{125}{14})](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%28%5Cfrac%7B107%7D%7B14%7D%2C%5Cfrac%7B125%7D%7B14%7D%29)
In decimals we get:
![(x,y)=(7.6,8.8)](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%287.6%2C8.8%29)
