There's no if about it,

has a zero

so

is a factor. That's the special case of the Remainder Theorem; since

we'll get a remainder of zero when we divide

by

At this point we can just divide or we can try more little numbers in the function. It doesn't take too long to discover

too, so

is a factor too by the remainder theorem. I can find the third zero as well; but let's say that's out of range for most folks.
So far we have

where

is the zero we haven't guessed yet. Again we could divide

by

but just looking at the constant term we must have

so

We check

We usually talk about the zeros of a function and the roots of an equation; here we have a function

whose zeros are
Answer:
Dori:3x+3y=11.25
Nemo:4x+2y=10
Step-by-step explanation:
Let x and y represent tacos and double Deckers respectively.
For three tacos and three double Deckers, Dori pays $11.25
Writing an equation the statement, we obtain
3x+3y=11.25
Also,for four tacos and two double Deckers, Nemo pays $10
This implies
4x+2y=10
Answer:
step1 - distributive property
step2 - associative property
step3 - cumulative property
step4 - associative property
Step-by-step explanation:
Answer:
Step-by-step explanation:
Standard form: Ax+By=C
Change C to 53
Ax+By=53
He could have added a combination of $1 bills and $5 bills or just $1 bills.
I hope this is right
