At Bombinoes, if he delivers 10 pizzas, he will make $81. y = 2.50x + 56

At Little Squeezers, if he delivers 10 pizzas, he will make $78. y = 3x + 48

At Pizza Tent, if he delivers 10 pizzas, he will make $79.50. y = 2.75x + 52

Little Squeezers would pay him the most if he delivered 20 pizzas. They would pay him a total of $108.

In the system of equations, r and s are constants. If the system has infinitely many solutions, what is the value of rs?

exis [7]

Answer: B) -48

Step-by-step explanation:

If the system of two linear equations $a_1x+b_1y=c_1\ \&\ a_2+b_2y=c_2$ has infinitely many solutions , then

$\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}=k$

For the given system of linear equations : $rx-sy=26\\4x+3y=13$

We , will have

$\dfrac{r}{4}=\dfrac{-s}{3}=\dfrac{26}{13}=2\\\\\Rightarrow\ r= 4\times2=8\ \ \&\ \ s=2\times-3=-6$

The value of $rs=(8)\times-6=-48$

Hence, the value of rs is -48.

Thus , the correct option is B) -48.
