Answer: B) -48
Step-by-step explanation:
If the system of two linear equations
has infinitely many solutions , then
![\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}=k](https://tex.z-dn.net/?f=%5Cdfrac%7Ba_1%7D%7Ba_2%7D%3D%5Cdfrac%7Bb_1%7D%7Bb_2%7D%3D%5Cdfrac%7Bc_1%7D%7Bc_2%7D%3Dk)
For the given system of linear equations : ![rx-sy=26\\4x+3y=13](https://tex.z-dn.net/?f=rx-sy%3D26%5C%5C4x%2B3y%3D13)
We , will have
![\dfrac{r}{4}=\dfrac{-s}{3}=\dfrac{26}{13}=2\\\\\Rightarrow\ r= 4\times2=8\ \ \&\ \ s=2\times-3=-6](https://tex.z-dn.net/?f=%5Cdfrac%7Br%7D%7B4%7D%3D%5Cdfrac%7B-s%7D%7B3%7D%3D%5Cdfrac%7B26%7D%7B13%7D%3D2%5C%5C%5C%5C%5CRightarrow%5C%20r%3D%204%5Ctimes2%3D8%5C%20%5C%20%5C%26%5C%20%5C%20s%3D2%5Ctimes-3%3D-6)
The value of ![rs=(8)\times-6=-48](https://tex.z-dn.net/?f=rs%3D%288%29%5Ctimes-6%3D-48)
Hence, the value of rs is -48.
Thus , the correct option is B) -48.
Answer:
Well, the only thing you should do is to use the formula.
if the bases are: a, b
and the height is=h
Then, this is your formula, S=½(a+b)×h
Step-by-step explanation:
Aight,
100dm=10m
S=10m
now, the formula
10=½(2.1+1.9)×h===> 20=4h==> h=5m
Answer:
6 pencils
Step-by-step explanation:
divide $3.30 by $0.55 and you get 6.
It's 75. After you wrote down all the possibilities for what G could be, just find the one that has a combination of numbers that add up to 12. 75 is 7+5=12
