L+S=8, L=8-S
500L+200S=2200, using L from above in this equation gives you:
500(8-S)+200S=2200
4000-500S+200S=2200
4000-300S=2200
-300S=-1800
S=6, and since L=8-S:
L=2
So Rita bought 2 large packets and 6 small packets.
With exponential functions of the form y equals short dash a times b to the power of x, as x goes to positive infinity, the y-values tend towards <u>negative infinity</u>.
The correct option C.
<h3>What is negative infinity?</h3>
The number's value. The global object's Infinity property has a negative value, which is the same as NEGATIVE INFINITY. It acts a little differently from mathematical infinity in the following ways: NEGATIVE INFINITY is the result of multiplying any positive value by NEGATIVE INFINITY, including POSITIVE INFINITY.
<h3>What is exponential functions?</h3>
F(x)=exp or e(x) is a mathematical symbol for the exponential function. Unless otherwise stated, the term normally refers to the positive-valued function of a real variable, though it can be extended to the complex numbers or adapted to other mathematical objects like matrices or Lie algebras.

a.) positive infinity
b.) zero
c.) negative infinity
d.) one
Answer:
a quadratic function
Step-by-step explanation:
A quadratic function is a second-degree polynomialfunction, and when graphed is called a parabola.
For this case we propose a rule of three:
foot -------------> 
hour
x -----------------------------------> 1 hour
Where "x" represents the amount of foot in one hour.
So, we have
foot every hour.
Answer:
foot every hour
Answer:
D
Step-by-step explanation:
A function is written in slope intercept form (y = mx + b)
so we first have to find the y-intercept or "b" in the question it states that they started off 400 miles away so that would be the "b" then you would need to find the m or slope and in the question it says after seven hours they where 50 miles away and 400 minus 50 is 350 so they traveled 350 miles in 7 hours so you then have to divide 350 by 7 and you get the slope 50 but since it is to find out how far away they are we make it negative giving you the equation y = -50 +400. Hope you found this helpful :D
