Answer:
and
Step-by-step explanation:
First of all, even if the system is of 4th degree, by looking at the shape of the equations I am expecting up to 2 solutions.
The easiest way to solve it, since both equation are in the form y= something, is to equate both RHSs.
which tells us that either or
Now we can replace these value of x in one of the two to finish our work:
Answer: D: 2 1/2
Step-by-step explanation:
Answer:
2(1.25)+1.99+x≤5
Step-by-step explanation:
Because it says "at most $5" that means it would be either 2(1.25+1.99)−x≤5
or 2(1.25)+1.99+x≤5, which narrows it down to two. The reason it is the second option is because she is only buying two cards that cost $1.25, hence this part of the equation: <u>2(1.25)</u> +1.99+x≤5.
If you would illustrate the problem, you will be able to
formulate a triangle with the measurement of the hypotenuse (distance between
the two shops) to be missing. Using the Pythagorean Theorem, the formula to
compute for the hypotenuse is:
c = √a^2 + b^2
c = √(20)^2 + (13.5)^2
c = √400 + 182.25
c = √582.25
c = 24.13 km
Therefore, the distance between the two shops
is approximately 24.13 km.
