Answer:
yes
Step-by-step explanation:
A relation is a function in which for each input there is only one output.
In a relation, y is a function of x.
Now we look at the mapping
For input 6, -1 is the output
for input -1, 2 is the output
for input 4, 3 is the output
for input 0, 3 is the output
For each input , there is an output. Input is not repeating. Input is occurring only once.
So this relation is a function.
Answer:
Before anyone gives anyone money, Mario has 24 dollars and Roberto has 12 dollars. After they give each other money, both of them have 18 dollars.
Step-by-step explanation:
Mario has twice as much as Roberto, BUT if Mario gives Roberto 6 dollars, then they have the same amount.
M = 2R
M - 6 = R + 6
To isolate M, you need to add 6 on both sides.
M - 6 + 6 = R + 6 + 6
M = R + 12
M = 2R
Substitute M for the value above that we found.
R + 12 = 2R
Now we subtract R on both sides, so that only one side has the variable R.
R - R + 12 = 2R - R
12 = R
M = 2R
Substitute for the value of R.
M = 2 x 12
M = 24
we are given
quadratic equation as

now, we can find b and c from

we can see that coefficient of x^2 is 1
so, we will have to make coefficient x^2 as 1
so, we divide both sides by 3



now, we can simplify it

now, we can compare it with

we get


so, we get order pair as
