Answer:
A system of linear equations will have exactly one point of intersection, for example:
2x+y=5
-x+y=2
However, a system of linear equations with no solution will have no points of intersection, for example:
-4x+10y=6
2x-5y=3
Sorry about c. though I'm confused on how a pair of equations can have infinite points of intersection unless x or y equals all real numbers which could happen if x or y both equaled all real numbers maybe
And the point of interesection for the system of equations in the problem you attached as an image is (2,-1)
I attached a photo below, and one of how to graph it
Luis is finding 5 because 9 minus 6 is 3. 3 plus 2 equal 5 easy
Let's break down all the information we receive from the question.
One pair of shoes= three times as much as a scarf
One pair of shoes and one scarf= $32
We need to make an equation where 3s= pair of shoes and s=scarf. We then need to put one pair of shoes + one scarf = 32.
3s+s=32
Now add.
4s=32
You could use 4s=32 (or 32÷4=s).
Answer:
5%
Step-by-step explanation:
The question showing a growing function that commonly used in compound interest calculation. The formula for compound interest is:
A = P (1 +r) ^ t
A= amount of the balance after a period of t
P= principal, the initial money deposit
r= rate
t= time
The percent of balance increase should be represented by the rate(r). In this equation, the principal will be 130, (1+r) will be 1.05, and time will be x.
The value of rate (r) will be:
(1+r) = 1.05
r= 1.05-1= 0.05 = 5%
